This charges real funds. Paid calls can take several seconds, including payment verification, service work and settlement; longer tasks can take more. Call `get_service` FIRST: its `requestShape.endpoints[]` lists the callable paths with their HTTP method and price, and each `payServiceArgs` is the `slug`/`path`/`method` to pass here, after replacing any `pathParams` placeholder in `path` with a real value. A bare slug reaches the service base URL, which for a multi-endpoint API answers 404 instead of a payment challenge; only a single-endpoint service is called by slug alone. Send the endpoint's `payServiceArgs`: they carry an example only when it is `paid-run` or `challenge`. A `docs` example (and its `invokePath`) is unverified — use it only deliberately, filling any path parameter with the entity you want; otherwise build `body` from the endpoint description or the provider's docs. `method` may be omitted: it is taken from the catalog endpoint matching `path` (POST when the catalog names none) and echoed back under `request`. To accept a live quote, pass its `quoteId` before `expiresAt` with the exact same call arguments; the Router uses that cached challenge and exact fee-inclusive total. Keep `maxTotalCents` as an independent ceiling. Repeating an identical call (same arguments, no `fresh`) charges nothing new: on a deployment running API 1.48 or later it is answered within 24 hours from the first call's stored result, or its `pending` answer; on an older deployment it comes back as `already_paid`. For an ASYNC service, where you submit once and then poll a status endpoint with the same id, set `fresh: true` on every poll INCLUDING THE FIRST: otherwise each later poll reuses the first poll's idempotency key and gets the first poll's stored answer (or `already_paid`) back, so the status never advances. `fresh` makes each poll a distinct, separately billed call (the merchant charges per status call). Leave `fresh` off the submit and off any retry of a call whose outcome is unsure, because with `fresh` a retry is not de-duplicated and is charged again. A completed call returns `paid`, `upstreamStatus` (the vendor's HTTP status) and `response` (its body). `paid: true` means a payment was attempted, not that it settled, so read `payment.status` (`Settled`, `Issued` or `Failed`): `Issued` is not confirmed yet, which is neither a failure nor a reason to retry, and `Failed` does not prove nothing was charged, so check `deliveryStatus` in `list_payments` before paying again. With a non-2xx `upstreamStatus` it may still have cost the merchant price. Outcomes to act on: `{\"status\":\"pending\"}` means a payment was attempted and the service is still working, so whether it went through is not known yet; call `get_payment_result` with its `paymentId` every few seconds instead of calling pay_service again. `{\"status\":\"already_paid\"}` means this call's idempotency key already carries a payment whose result is not replayed here (the original call failed, its 24-hour result expired, the `requestId` was reused for a different request, or the deployment predates result replay, API 1.48); nothing new was charged, and it does not by itself say whether the original succeeded. Read the original with `get_payment_result` (`paymentId`) or `list_payments` (pass its `requestId`). A new `requestId` starts a separate, separately charged purchase: use one only after that read shows the original failed and the human still wants the result. `{\"error\":\"payment_indeterminate\"}` means the charge may or may not have landed: check `list_payments` first, and to retry reuse the returned `requestId` verbatim without `fresh` so the retry stays idempotent. `{\"error\":\"per_call_max_exceeded\"}` means no charge; raise `maxTotalCents` only after a deliberate decision and retry with the same requestId. `quote_not_found`, `quote_expired`, and `quote_mismatch` are named no-charge quote refusals; quote again rather than paying unpinned. `{\"error\":\"payment_failed\"}` is a definite decline (see `code`, `message` and `retryable`). These charge nothing: `{\"payable\":false}` (not payable via the Router; no upstream URL is ever returned), `service_not_found` (wrong slug), `catalog_unavailable` and `delegation_lookup_failed` (transient; retry later), `payment_not_started` (too little time remained to start a payment; retry with the same arguments), `no_delegation` (call `setup_delegation`), `router_controls_unavailable` (the API behind this server is too old to enforce `search`, `quoteId` or `maxTotalCents`; tell the human instead of retrying without them) and `credential_refused` (re-authorize). A paid result also carries `delegationId` and `budget`, the spending budget after this call (`capCents`/`spentCents`/`remainingCents`, cents with up to four decimals), so to say what has been spent or what is left, repeat `budget` rather than adding up your calls yourself; `budget: null` means it could not be read this time, not that it is zero (call `get_budget`). FUNDING (`funding`): omit it and the call is paid with your Nevermined credits when you hold credits that can pay it (a Nevermined Subscription allowance, welcome or top-up credits) and the endpoint carries a credits tariff (Nevermined pays the merchant; the call costs the tariff in credits, returned if the service does not answer successfully), otherwise from your delegation; pass `\"subscription\"` or `\"delegation\"` to choose. The price ceiling, and the credits left of a subscriber in good standing, are checked only when the call is made: a credits call refused for them (`insufficient_credits`, `subscription_cap_reached`, `subscription_ceiling_exceeded`) charges nothing and is NOT switched to your delegation, so follow its `alternative`. Without a subscription in good standing, your spendable credits are checked before the call, and a call they cannot cover (when no automatic credit pack would) is paid from your delegation, with `fundingCode` saying why. Every result that mentions funding states which funding was chosen: a subscription call returns `funding: \"subscription\"` with `creditsCharged`, `creditsStatus` and `creditsLeft` (a digit string read after the call; null means unavailable, not zero) (`Committed` = spent, `Reserved` = held or marked for refund, `Refunded` = returned) and no `budget`, plus `topUp` (`credits`, `amountUsd`) and `topUpMessage` when the call ran out of credits and charged one credit pack to the saved card to cover itself (credit top-ups on, and only on a call made with your own API key: a call made through an OAuth connection never charges a pack) — relay `topUpMessage` to the user, since their card was charged (it comes alone, without `topUp`, when the pack could not be read); `quoteId`, `maxTotalCents` and `delegationId` apply only to a delegation. `already_paid` states no funding: it answers for an earlier payment, which may have been funded either way, and a retry that lands on the other funding gets it even when the original succeeded and its result is still kept. To see which funding that payment used, read `fundingSource` from `list_payments` with its `requestId`. Subscription refusals charge nothing and no credits (unless they carry `topUps: \"bought\"`, below): `subscription_unavailable`, `no_active_subscription`, `subscription_not_eligible` (see `reason`), `subscription_rail_unsupported`, `subscription_ceiling_exceeded`, `insufficient_credits`, `credits_frozen` (every credit frozen by a card dispute; on a call with `funding` omitted and no delegation it names `setup_delegation`), `subscription_cap_reached`, `credit_daily_limit_exceeded` (wait until midnight UTC or ask the human to change their limit), `credit_budget_unavailable` (retry later) and `subscription_payment_refused`. Neither daily-budget refusal switches to a delegation; `credit_daily_limit_exceeded` carries `dailyLimitCredits` (number), `usedCredits`, `remainingCredits` (digit strings) and `resetsAt`. Other refusals say in `alternative` when the delegation can pay instead. With credit top-ups on, `insufficient_credits` on a call made with your own API key carries `topUps`, and a credit pack may have been charged even though the call was refused (no credits were spent on it); on a call made through an OAuth connection it carries none and no pack was charged: `paused` (a pack was declined; buying one from the Nevermined dashboard resumes them), `limitReached` (the monthly top-up limit), `pending` (a pack is being charged and may already be; retry in a moment), `unavailable` (no pack was charged; retry later) or `bought` (this call charged a pack but other calls spent it first; on `code` `BCK.SUBSCRIPTION_ROUTER.0009` retry, otherwise follow `message`). `credits_frozen` can carry `topUps: \"bought\"` too: a pack was charged, then frozen with the rest by a dispute. Any refusal with `topUps: \"bought\"` also carries `topUpMessage` and the pack’s `purchaseId`: relay `topUpMessage` to the user, since their card was charged.

Pass exactly what you would pass to `pay_service` (the same `slug`, `path`, `method`, `search`, `headers`, `body` and `delegationId`): the Router sends that request to the service unpaid, reads the price it asks for, and returns an opaque `quoteId`, its short `expiresAt`, the rail (`protocol`), the network and merchant amount (`settlement`) and the fee-inclusive total (`fee.capChargedCents`, whole cents rounded up; `fee.capChargedMicros` exact, in 1/10,000 of a cent). Unlike the `quote` on a get_service endpoint (the last merchant price the catalog observed, routing fee excluded), this is priced live for your exact request and includes the fee. Because the request really reaches the service, a service that does not charge for it performs it, so take care quoting a method with side effects; and a quote spends the same per-service rate limit as a payment, so quote once per decision rather than polling. It prices the delegation pay_service would charge (`optionSet: \"delegation\"`, naming its `delegationId`), or, with no delegation set up, what a personal crypto delegation would select (`optionSet: \"deployment\"`); in that case `nextTool` is `setup_delegation`: set one up and quote again before paying, since the delegation you create can select a different rail and price. It checks neither your remaining budget nor your wallet balance (see get_budget and wallet_balance). Next step (`nextTool: \"pay_service\"`): if `fee.capChargedCents` fits what you planned to spend, call `pay_service` before expiry with the same arguments, the quoted `delegationId`, `quoteId`, and `maxTotalCents` set to that figure as a number. The quote id fixes the exact challenge and fee-inclusive total while `maxTotalCents` remains an independent ceiling. `paymentRequired: false` means the service did not ask for payment for this request; `upstreamStatus` is its answer, and a non-2xx usually means the path, method or body is wrong. The service response itself is never returned. Outcomes, all charging nothing: `{\"payable\":false}`, `service_not_found`, `catalog_unavailable` and `delegation_lookup_failed` as in pay_service; `quote_unavailable` (no quote can be made here and retrying will not change that, so bound the price with pay_service `maxTotalCents` instead); `quote_failed` (the Router refused to price the call, or did not answer; see `code`, `message` and `retryable`); `credential_refused` (re-authorize). FUNDING (`funding`): chosen as pay_service would choose it. When you hold Nevermined credits that can pay it (a Nevermined Subscription allowance, welcome or top-up credits) and the endpoint carries a credits tariff the answer is `{\"funding\":\"subscription\",\"credits\":…,\"tariffVersion\":…}`: the credits one call costs from the published tariff (the service is not contacted, and there is no `quoteId` or cent total); then call pay_service with the same arguments. The price ceiling, and the credits left of a subscriber in good standing, are checked only when pay_service makes the call, so this answer does not promise the call will be paid with credits. Pass `funding: \"delegation\"` to price the delegation instead. Subscription refusals are named as in pay_service. When `settlement.scheme` is `session`, the merchant is paid out of a deposit in a payment channel, and `sessionDeposit` says what this call would do to it: `action` is `open` (the first call locks a deposit), `top_up` (it locks more), `none` (no new money leaves the wallet), `closing` (the call would be refused, nothing moves; quote again once it has closed) or null (what the call would do could not be stated, and pay_service may refuse it); `approxCents` is how much would move into the deposit, in cents, the network fee not included, and `basis` says whether that is `sized` for this budget and wallet or an `upper_bound`. That money can far exceed the price.

Money is in CENTS: `capCents` is whole cents; `spentCents` and `remainingCents` can carry up to four decimals because the budget is charged per call at 1/10,000 of a cent (e.g. `\"1.632\"` = 1.632¢), and `spentCents + remainingCents = capCents` while the budget is within its cap.

It is that WALLET's total, shared by every budget paying from it, not a figure of this budget's own: it is NOT spent and NOT charged to this budget, it can pay further calls only to the merchant holding each channel, and what is unused comes back to that wallet when the channel closes, after 15 minutes without use; `message` then says so. An empty list means nothing is locked; `null` means it could not be read, and `message` then says that too. `sessionChannels`, when present, is the history behind that: each payment channel this budget used, newest first, with the `merchant`, its `status`, what was deposited (`deposit`, or `depositAtomic` in raw units when `symbol` is null), what came back (`refund`, null until the channel has closed and the refund is confirmed) and `openedAt`/`closedAt`. It is what explains money leaving the wallet and coming back when no payment shows it: a payment record carries one call's price, never the deposit. `sharedWithOtherBudgets` means the wallet's channel also served another budget, so its figures are not this budget's alone, and `depositConfirmed: false` means the open is not confirmed, so the deposit may not have landed. `sessionChannelsTruncated: true` means the list holds only the newest channels and older ones exist; `message` then says so.

WHAT IT DOES NOT COVER, so you do not mis-diagnose: a delegation backed by an ORGANIZATION wallet is paid from that wallet, not this one; and a CARD delegation has no wallet at all — there `BCK.ROUTER.0009` is the card ISSUER declining, with nothing to top up, so this tool does not apply and the answer is a different card. BY RAIL: on MPP the wallet is checked BEFORE anything is signed, and the `BCK.ROUTER.0009` you get back already names the wallet and the chain — what it never says is HOW MUCH is there, which is what this tool supplies. On x402 there is NO balance pre-check and `BCK.ROUTER.0009` is never raised: the credential is minted, budget is reserved, and a short wallet only surfaces when the merchant's on-chain transfer fails — by which point your budget is already committed, and the reserve comes back only once the reconciler has seen the authorization expire unconsumed. So on that rail read the balance BEFORE you pay, not after. By default this reports EVERY network this deployment settles on, and you must read the one the merchant quoted: a healthy balance on one chain says NOTHING about the other, and most services settle on only one of them. Pass `network` (a chain id) to read a single chain. A token whose `atomic`/`formatted` is `null` was NOT READ (the on-chain read failed) — that is not a zero balance, and reporting it as empty is wrong; a chain that could not be read at all comes back as an entry with `error` instead of `balances`. This tool diagnoses and fixes nothing: there is no on-ramp and you cannot top your own wallet up, so a genuine shortfall is a stop condition — report the network and the amount to your human, and do not retry the payment. Each entry with `balances` also carries `lockedInChannels` when the API reports it, per token (`atomic` in the token's smallest unit, `formatted`, `symbol`): money your payer wallet (the one the Router signs MPP payments with, which is this wallet once your account is migrated) has deposited into payment channels with merchants that charge per call over an MPP session, held in the channel's escrow. It is NOT part of `balances` and it is NOT spent: it is still the human's. It can pay further calls only to the merchant holding that channel, never anyone else, and what is unused comes back to that wallet when the channel closes, after 15 minutes without use. Report it beside the balance, never as spending, and never count it toward paying any other merchant. Here a null `symbol`/`decimals`/`formatted` means a token Nevermined does not recognise, NOT an unread amount: report `atomic` as raw units of `token`. An empty list means nothing is locked; `lockedInChannels: null` means it could not be read, which is not the same as nothing locked. When you have a Nevermined Subscription the result also carries `subscription` (the credits left, reset date and plan, as in get_budget), and whenever you hold credits, subscribed or not, `credits` (total, spendable and by kind and expiry, as in get_budget): credits are not held in this wallet and are not money; calls paid with credits are paid by Nevermined, not from this wallet.

Nothing was called. No status page is linked from the site, the footer, llms.txt or the guides, and no status host was checked (0). With no readable incident history the record takes the default (5). Listing pages show a health count with no history, such as '10/10 endpoints healthy' on Minifetch. No rate limit with numbers was found in llms.txt, the guides or the CLI help. The only cap is a per-key spending limit (0). The Balance guide says to retry a 503 shortly without minting a new credential, replays of a settled top-up `finalize` call are idempotent, a failed order answers 409, and the card flow says 'a retry is a new order'. No 429 or Retry-After guidance was found. Termix earned 8 for the same kind of guidance with idempotency keys on writes (7 of 15). No SLA was found, and the terms supply the service 'as is' (0). The about page labels the product 'v.01 / Beta' (0). Total 12.\n- Nevermined API + MCP (63): Hosted lines, graded on the Catalog MCP server (which carries the Router's route_by_intent, quote_service and pay_service) and the REST API, the surfaces both graders used. status.nevermined.ai is an Upptime page built from the public nevermined-io/uptime repository, with history for five root URLs (website, app, docs, and the sandbox and live API roots). It doesn't monitor mcp.live.nevermined.app or any Router route. At 16:50 UTC on 17 October 2026 the repository's newest commit was the daily summary of 6 October, and its daily response-time records stop on 5 September, so the page had recorded nothing for 11 days. Snipcart earned 15 for an Upptime page that checks root URLs and is still running, and Brave's page earned 10 with its components unmonitored (10 of 20). The record from 28 July (when the API monitors started) to 6 October shows both APIs clean and one docs outage, 502s from 20:09 UTC on 2 September to 05:39 UTC on 3 September, about 9.5 hours. The docs aren't a surface an agent calls, so minor incidents only (20). The Router documents per-key, per-slug and IP-keyed global 429 buckets without request-rate numbers, plus a default of 10 concurrent routed requests per user and about 60 device-flow polls a minute per IP. Paid earned 7 for limits described without numbers, and the published figures add 1 (8 of 15). 429s carry Retry-After, the global bucket adds Retry-After-short, Retry-After-long and RateLimit headers, every error carries a retryable flag, and payments take a requestId, with documented handling of indeterminate and duplicate payments (15). No SLA in the terms or on the pricing page (0). The Catalog MCP and the Router carry no beta or preview label (10).\n\n### Transparency \u0026 trust: Nevermined API + MCP +38\n\n- FluxA AgentMarket (32): The editorial half. The marketplace, proxy and gateway are closed. The terms (effective 14 January 2026) cover pricing, refunds and acceptable use but name no governing law, termination terms, liability for third-party listings or creator obligations, and the company appears only in the footer. The CLI is Apache-2.0 (8 of 30). The privacy policy (14 January 2026) lists account, payment and usage data and says identity isn't shared with model providers. It says nothing on prompts, API payloads, retention, training or data location (6 of 30). No deprecation policy or dated notice was found, and the terms may change 'at any time' (0 of 20). The policy names Stripe and 'OpenAI/Anthropic API' as a non-exhaustive list, while the models page lists AIHubMix, UnifyLLM and Baidu AI Cloud as providers. No locations are given (4 of 20). Total 18. The provenance half is computed from the provenance block.\n- Nevermined API + MCP (70): The editorial half. The SDKs are Apache-2.0, while the platform, API and MCP server are closed (the registry names a private repository, nevermined-io/nvm-monorepo). The terms at nevermined.ai/legal/terms are published but undated, are written for a wallet-connected app that 'does not transfer any Crypto Assets', don't mention cards, Delegations, the Router or the Subscription, and let Nevermined end the agreement without notice. Paid earned 17 for a closed platform under an undated agreement with open SDKs (17 of 30). The Data Policy on nevermined.app gives retention by category (account and transaction records ten years, audit logs five, usage data 24 months, analytics 12 months, masked session recordings 30 days, paid call responses 24 hours), which agrees with the MCP tools' 24-hour result window, and says stored responses aren't used for training. The older policy the nevermined.ai footer links is a generic notice for the marketing site, naming visitor identification partners (retention.com, RB2B), and the Data Policy says that site has its own notice, so the two don't conflict on the platform. The Data Policy is undated (24 of 30). The versioning page is a deprecation policy, with the 1.0 floor supported indefinitely, no forced sunsets and breaking changes gated behind pins, and the SDK changelogs carry dated deprecations such as the `environment` option. The Router refuses legacy API keys (403 BCK.ROUTER.0008) with no date or notice found (16 of 20). Annex B lists seven sub-processors with locations and transfer mechanisms and promises 60 days' notice of changes, hosting is in the EU or Switzerland, and product analytics run on PostHog's EU instance with a documented opt-out. The cloud host and compliance platform aren't named, and Privy (sign-in) and Braintree (cards), which the auth manifest and docs name, aren't listed (14 of 20). The provenance half is computed from the provenance block.\n\n### Schema \u0026 documentation: Nevermined API + MCP +32\n\n- FluxA AgentMarket (53): No OpenAPI file was found. llms.txt names none and the documentation site, docs.fluxapay.xyz, couldn't be read because its robots.txt couldn't be. The discovery response has documented fields (`apiServers`, `skills`, `models`, `pagination`), a GET on each listing's `urls.access` returns its endpoints and prices as JSON per the skill-creation guide, and the LLM endpoints follow the OpenAI and Anthropic formats (8 of 25). llms.txt and Markdown guides (getting-started.md, currency.md, create-skill.md, the APIs and Balance guides) written for agents (10). The guides say when to use `search` against `query`, that the external catalogues are a last resort and which rail fits which job. Listing descriptions come from creators and 17 of the first 50 skills have none (12 of 20). `type` is an enum that answers 400 to unknown values, `limit` is bounded at 1,000, and the chat and messages bodies follow published formats. Listing endpoints are described by each creator (9 of 15). curl examples for discovery, models and payment, a status table in the Balance guide with the action for 401, 503, 404, 402 and 409, and seven named mandate errors in the APIs guide (11 of 15). Paths carry `/llm/v1/` and llms.txt names minimum CLI versions, but no changelog was found (3 of 15). Total 53.\n- Nevermined API + MCP (85): Every one of the 12 Catalog MCP tools has a typed JSON Schema input (tools/list read without a credential on 17 October 2026). llms.txt links three public OpenAPI files, openapi.json (OpenAPI 3.1, 39 paths including 11 Router routes), oauth-openapi.json (12 paths) and organizations-openapi.json (65 paths). `POST /router/select`, the REST side of route_by_intent, and the `/api/v1/mpp/challenge` and `/api/v1/mpp/settle` routes in the MPP seller guide aren't in any of them. The catalogue's REST reads answer 403 to outside callers by design, so they aren't counted. Missing routes cost 3, as for Presidio and ComplyCube (22 of 25). llms.txt with a Markdown twin of every page, and a Docs MCP server (10). The descriptions state purpose and when to use each tool instead of its neighbour, such as route_by_intent 'instead of search_services when you want the right service for a task', and when not to, such as autoPay suiting only single-endpoint services. They are long, which ergonomics counts (18 of 20). Enums on `protocol` and `funding`, bounds on `pageSize`, `limit` and `maxTotalCents`, a uuid format on `paymentId` and `additionalProperties: false`, but `body` has no type, `headers` is a free string map, `method` a free string and `from` and `to` plain strings with no date format. Paid earned 12 for enums and required flags beside free-form maps, and an untyped body sits below that (11 of 15). Each tool page has request and response examples and a refusals table, and the API error model documents a stable `BCK.*` code, message, hint and retryable flag, with a full code list (15). The API is versioned by MAJOR.MINOR with a `Nevermined-Version` header, per-key pins and a written compatibility policy. The SDKs keep dated CHANGELOG files and there's a dated product update of 15 October 2026, but no changelog for the platform, API or MCP server was found. Paid earned 7 for versioning with no API changelog, and the SDK changelogs add 2 (9 of 15).\n\n### Security \u0026 auth: Nevermined API + MCP +23\n\n- FluxA AgentMarket (51): `fxa_live_` keys are created by a person at /keys and shown once, each with a spending limit in Units that changes within seconds, and are revoked immediately over `DELETE /llm/keys/\u003cid\u003e`, with written rotation steps. Key management needs a 5-minute Agent VC, never a key, and creation can be set to need a person's approval. No permission scopes beyond the spending limit were found, and no secret in a URL (24 of 30). Wallet payments need a mandate a person signs with a USDC budget and an expiry, and the Balance guide says to confirm every top-up with the user. The APIs guide tells agents not to ask before paying within a signed mandate, and no read-only key was found (14 of 20). The marketplace returns content from third-party APIs and installs third-party skills. Results carry a `fluxa` or `bazaar` source tag, but entries named `ssrf1`, `keyprobe` and `tooltest1` are tagged `fluxa`, no review of uploads is described, and no guidance on treating responses or skills as untrusted was found (2 of 15). The balance endpoint returns available, spent, burn per day and owed, the ledger lists spend and purchases per merchant, and the wallet skill reads an `X-LLM-Cost` header on model calls (11 of 15). No disclosure policy, bug bounty, certification or advisory was found. security.txt couldn't be read and is scored absent, and the privacy policy says only 'industry-standard security measures' (0 of 20). Total 51.\n- Nevermined API + MCP (74): Plain API keys are bearer credentials per environment, accepted only in the Authorization header (the auth manifest rules out a query parameter), with Admin and member roles and no scopes found, and an admin key can move organisation funds. MCP hosts can use OAuth 2.1 with PKCE and the commerce scope, whose short-lived credential spends only from the Delegation a person approved, with one-time refresh tokens and revocation at `/oauth/revoke`. The device flow mints a key for one agent's plan. OpenRouter earned 25 for bearer keys and OAuth PKCE with no permission scopes, the same kind of model (25 of 30). Delegations carry a hard cap, transaction count and expiry, are revocable and are never widened or extended in place. An agent can't set its own cap, since setup_delegation hands a person one URL, and Visa delegations need a passkey. Recipient scope is optional and unset means any merchant, there's no read-only key, and nothing asks before a paid call within the cap. Composio earned 16 with read-only filters and optional approvals, and here caps a person sets stand in for the missing read-only mode (16 of 20). pay_service relays merchant responses unchanged. Listing text is sanitised and moderated, route_by_intent ranks without a model reading listings and get_service marks `docs` examples as unverified provider documentation, but no guidance on treating merchant responses as untrusted was found (6 of 15). Per-payment records with delivery status in list_payments, an organisation activity feed (`GET /organizations/{orgId}/activity`), an `x-correlation-id` on every response, connected agents that can be listed and revoked, and audit logs of actions under Agentic Tokens kept five years per the Data Policy. Unpaid tool calls leave no record the operator can read (14 of 15). security.txt is valid on nevermined.app (security@nevermined.io, expires 2 May 2027) and missing on nevermined.ai. The certifications page and pricing page claim SOC 2 Type II, ISO/IEC 27001:2022 and PCI SAQ-D, while the Data Policy's section 8.5 calls the ISO 27001 programme in progress with Stage 2 scheduled. The Trust Center renders only with JavaScript and wasn't read, no bug bounty was found, and GitHub advisories couldn't be read because GitHub's API refused us. Composio earned 12 for SOC 2 Type II and private reporting without security.txt (13 of 20).\n\n### Maintenance \u0026 community: Nevermined API + MCP +17\n\n- FluxA AgentMarket (64): Read for a closed service. No changelog or dated release notes were found. The models page says the catalogue was 'last updated November 5, 2026', and `@fluxa-pay/fluxa-wallet` 0.6.0, the CLI that carries the `market` commands llms.txt relies on, was published on 6 November 2026 (30). The CLI had eight releases between 10 August and 6 November 2026, 0.4.12 to 0.6.0 (20). Support is a Discord server and support.fluxapay@fluxapay.xyz, neither tested, and GitHub issues couldn't be read because the GitHub API refused us (3 of 15). No AgentMarket SDK. The TypeScript CLI is the official client and the LLM endpoints take OpenAI and Anthropic SDKs. Not an MCP server, so the registry line reads as SDKs (7 of 15). The CLI repository has 7 test files and no CI workflow, and the npm package declares no repository. `@fluxa-pay/fluxa-connect-mcp` points to a repository that isn't public (4 of 10). Total 64.\n- Nevermined API + MCP (81): Read for a hosted service with open SDKs. The MCP server reports version 1.69.0, published to the official registry on 15 October 2026, the day of Nevermined's product update on the Subscription, Readiness scoring and the Router (30). 14 registry versions between 29 September and 15 October, and SDK releases 1.11.0 to 1.13.0 (TypeScript) and 1.16.1 to 1.18.0 (Python) between 18 August and 9 September (20). The platform is closed and GitHub's API and web pages refused our reader, so the issue queues are unread and the 0 to 15 scale for closed services applies, as in the Paid dossier. Dated SDK changelogs that link fixes to issues (#422 fixed by #423 in 1.11.2 on 1 September), a dated product update and Discord support on the Free plan, not tested (8 of 15). io.github.nevermined-io/catalog is active in the official MCP registry under a GitHub-verified namespace, and the SDKs are current in TypeScript and Python (15). The SDK repositories run test, lint, release and docs workflows with Dependabot and lockfiles. CI results weren't read (8 of 10).\n\n### Agent ergonomics: Nevermined API + MCP +10\n\n- FluxA AgentMarket (66): Graded on the HTTP API. Discovery takes `limit` up to 1,000, `type` and `tags` filters and a Markdown format, with no field selection, and listing responses vary by creator (15 of 25). `limit`, `offset` and `nextOffset` on discovery, `search` and `query` modes, and the ledger takes `kind`, `limit` (maximum 100) and `offset`. llms.txt says filters ignore `limit` and `offset` (16 of 20). The Balance guide's status table gives an action for each status, the APIs guide names `insufficient_balance`, `mandate_budget_exceeded`, `agent_not_registered` and others, and a model served only on Messages answers 400 on chat (15 of 20). `finalize` replays are idempotent and a dead order answers 409 with the instruction to start a new one. No idempotency key on paid calls was found (10 of 20). The LLM endpoints accept any OpenAI or Anthropic client, discovery needs no parameters, and the only official client is the TypeScript wallet CLI (10 of 15). Total 66.\n- Nevermined API + MCP (76): Graded on the Catalog MCP server, with the REST API where a line covers it. Twelve tools put it in the 11 to 30 band, with no toolsets or read-only subsets. The definitions come to about 41,000 characters (pay_service alone about 9,800), and the band is read without a size deduction, as openmetadata (16 tools, 49,602 characters) and plane (30 tools, about 67,000) were (15 of 25). search_services takes `pageSize` 1 to 100 but returns only the first page, since its `pageToken` can't be passed back, route_by_intent's shortlist takes `limit` 1 to 20, and list_payments filters by Delegation and date and stops at 1,000 records with no cursor (14 of 20). Refusals come back as JSON with `error`, `code`, `retryable` and `instructions`, often naming the next tool, such as `no_delegation` pointing to setup_delegation (20). A repeated paid call with the same `requestId` is answered from the stored result for 24 hours, and `payment_indeterminate` and `already_paid` are documented. None of the 12 tools carries readOnlyHint or destructiveHint, though each declares a `securitySchemes` entry (`noauth`, or `oauth2` with the commerce scope). Composio earned 15 with annotations and no idempotency keys, so the reverse case takes 12 (12 of 20). Most tools need one argument or none, autoPay defaults to off, and official SDKs ship in TypeScript and Python (15).\n\n## Score by category\n\n| Category | Weight | FluxA AgentMarket | Nevermined API + MCP | Edge |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% (20 this run) | 12 | 63 | Nevermined API + MCP +51 |\n| Performance | 10%, pending | pending | pending | not scored in this run |\n| Schema \u0026 documentation | 13% (16.2 this run) | 53 | 85 | Nevermined API + MCP +32 |\n| Agent ergonomics | 13% (16.2 this run) | 66 | 76 | Nevermined API + MCP +10 |\n| Security \u0026 auth | 14% (17.5 this run) | 51 | 74 | Nevermined API + MCP +23 |\n| Payments \u0026 pricing | 10% (12.5 this run) | 75 | 70 | FluxA AgentMarket +5 |\n| Task success | 10%, pending | pending | pending | not scored in this run |\n| Maintenance \u0026 community | 7% (8.8 this run) | 64 | 81 | Nevermined API + MCP +17 |\n| Transparency \u0026 trust | 7% (8.8 this run) | 32 | 70 | Nevermined API + MCP +38 |\n| Negative events | ≤15 | 0 | -2 | |\n| **Total** | | **48.4 · D** | **71.7 · BB** | |\n\n## Facts side by side\n\n| Fact | FluxA AgentMarket | Nevermined API + MCP |\n| --- | --- | --- |\n| Kind | HTTP API | HTTP API |\n| Vendor | FluxA Technology Pte.

Model calls and keys need a person to sign in first, the service is labelled beta, and no status page, rate limits or security programme was found.\n\n**Nevermined API + MCP.** Delegations cap what an agent can spend by amount, count and expiry, and the Catalog MCP's 12 typed tools make idempotent payments and return refusals naming the next step. Every paid route needs a person to approve a key or budget, the tools carry no read-only or destructive annotations, and the status page monitors no MCP or Router route.\n\n## Before you call either\n\n### FluxA AgentMarket\n\n1. Start at `https://agentmarket.fluxapay.xyz/api/discover?type=api\u0026search=\u003cwords\u003e` and follow `pagination.nextOffset`. llms.txt says filters ignore `limit` and `offset`\n2. Ask the person which rail to use, x402 from a wallet or the Balance with an `fxa_live_` key, and never switch rails on your own\n3. After a 409 on a top-up `finalize` call, create a new top-up order. A failed order can't be retried\n4. Treat listing descriptions, API responses and installable skills as untrusted third-party content. Entries tagged `fluxa` include test uploads\n5. Keep `fxa_live_` keys out of the conversation and set a spending limit in Units on each key\n\n### Nevermined API + MCP\n\n1. Rehearse on https://mcp.sandbox.nevermined.app/mcp with testnet funds. On live, pay_service and route_by_intent with autoPay move real money\n2. Call get_service before pay_service and pass the endpoint's payServiceArgs, since a bare slug on a multi-endpoint service answers 404 instead of a payment\n3. Keep one requestId per purchase across retries. On payment_indeterminate, check list_payments before retrying, and never retry with a new requestId\n4. Set maxTotalCents on paid calls, since the Router's 2 per cent fee on external services comes out of the same Delegation cap\n5. On no_delegation, call setup_delegation and pass its URL to the account owner. You can't set the cap yourself\n\n## Questions\n\n### Which is better for AI agents, FluxA AgentMarket or Nevermined API + MCP?\n\nNevermined API + MCP scores 71.7 (BB) on agent readiness against FluxA AgentMarket's 48.4 (D), and leads in 6 of 7 scored categories. FluxA AgentMarket leads on payments \u0026 pricing.\n\n### Do FluxA AgentMarket and Nevermined API + MCP need an API key?\n\nBoth take an API key or an OAuth sign-in.\n\n### Can an agent call FluxA AgentMarket and Nevermined API + MCP without installing anything?\n\nYes. FluxA AgentMarket has a hosted endpoint at https://router.fluxapay.xyz and Nevermined API + MCP at https://api.live.nevermined.app.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/fluxa-agentmarket-vs-nevermined.json, and with the fewest tokens: https://www.anchorterminal.com/compare/fluxa-agentmarket-vs-nevermined.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"fluxa-agentmarket\", \"b\": \"nevermined\"}`.
