No llms.txt; the skills hub ships Markdown SKILL.md files with endpoint tables for seven product areas, read-only (6 of 10). One docs page per endpoint with a description, permission and weight, but no when-to-use guidance (12 of 20). Typed parameter tables with enums for type and side and required flags (11 of 15). Request and response examples per endpoint and a unified six-digit error code scheme introduced with V2 (10 of 15). Dated changelog with V1 to V2 versioning (13 of 15). 60.\n- Uniswap Trading API (90): OpenAPI 3.0 file (Token Trading 1.0.0) for the Trading and LP APIs, about 33 paths with `x-internal` markers on the margin and 4337 operations (25). llms.txt, llms-full.txt and a Markdown twin of every docs page (10). Operation summaries are one line, but the guides say which routing types go to `/swap`, `/order` and `/plan`, when UniswapX quotes are returned and when a 404 means change the request (14 of 20). Enums for routing types, urgency and position statuses, required fields and bounded integers such as `limit` 1 to 20 (12 of 15). Examples on every guide page and error schemas for 400, 401, 404 and 429 with a stable `errorCode` enum and per-code retry advice (14 of 15). A /v1 path, a changelog with posted and effective dates and a 30-day minimum sunset policy (15). Total 90.\n\n### Maintenance \u0026 community: Uniswap Trading API +15\n\n- KuCoin (73): Read as a closed hosted service. The changelog's newest past entry is 2 November 2026 and the universal SDK was pushed 15 September (30). Nine dated changelog entries since 5 August 2026 (20). A Telegram API group (t.me/KuCoin_API) and api@kucoin.com for limit requests, no public issue tracker for the API; the SDK repository's issues were not checked (10 of 25). Official SDKs current in five languages, no MCP registry presence (13 of 15). No package health signal checked (0 of 10). 73.\n- Uniswap Trading API (88): Read as a closed hosted service. The newest changelog notice is dated 22 October 2026 (30). Notices of 20 August, 21 September and 22 October 2026, three in 90 days (20). A help form for developer support that says it won't debug integrators' code, and uniswap-ai with 6 open issues and a push on 26 October (14 of 25). Official TypeScript SDKs current (@uniswap/v4-sdk 2.4.4 with provenance) and the uniswap-ai skills, though no client for the API itself; no MCP registry entry (15). Trusted publishing with provenance on npm, CI and lint hooks on uniswap-ai (9 of 10). Total 88.\n\n### Agent ergonomics: Uniswap Trading API +10\n\n- KuCoin (62): Read for the API alone, since there is no MCP server. Responses take limit and cursor parameters on list endpoints and the order book depth is a parameter (14 of 25). Pagination and symbol filters on orders, fills and ledgers (15 of 20). Codes and messages per response, with the V2 scheme claimed to be clearer; the rate-limit page's own examples contradict its table, which costs an agent a turn (12 of 20). clientOid on orders makes retries safe; no MCP annotations to read (10 of 20). Three required fields on a spot order, official SDKs in five languages (11 of 15). 62.\n- Uniswap Trading API (72): An API, read for response sizing. Quotes and calldata are compact and `/tokens` takes a limit; the quote can carry the swap calldata to save a call (20 of 25). `GET /orders` and `GET /swaps` poll status by id, `/swappable_tokens` and `/tokens` filter by chain and sort, with little pagination elsewhere (12 of 20). Stable `errorCode` values with a `detail` string and a `requestId`, and the docs say which codes to retry (18 of 20). No idempotency key; a swap is a signed transaction whose nonce prevents a double spend, and the docs warn about nonce collisions with pending transactions (12 of 20). Few required fields on `/quote`, defaults for slippage and urgency, but no official client library for the API and signing needs ethers.js, viem or web3.js (10 of 15). Total 72.\n\n### Security \u0026 auth: Uniswap Trading API +8\n\n- KuCoin (55): API key with a user-set passphrase, HMAC-SHA256 signing, nine permission groups, IP allow-lists required for Withdrawal and FlexTransfers, trading keys without an IP disabled after 30 days of inactivity, revocation on the management page; no OAuth and no expiry on General keys (24 of 30). A General-only key is a true read-only mode and withdrawals are a separate permission; no confirmation step for writes beyond the key scope (12 of 20). Tools return the exchange's own data (10). The API key info endpoint shows permissions and IP lists; no per-call audit log was found (5 of 15). No security.txt, no disclosure policy or bounty on a page we could read, a whistleblower notice on the legal page (4 of 20). 55.\n- Uniswap Trading API (63): A single `x-api-key` header, no scopes, no IP allow-list; revocation and rotation happen in a dashboard robots.txt disallows, so unchecked; nothing in a URL (18 of 30). The API never holds keys or funds, every value transfer needs the caller's signature on `permitData` and the transaction, and the swapper sets slippage (16 of 20). The API returns routes and token lists, not untrusted content (10). The dashboard presumably shows key usage; not read, and no per-call log is documented (5 of 15). security.txt on app.uniswap.org with a Cantina bounty and security@uniswap.org, protocol audits in the docs; no SOC 2 or disclosure timeline read (14 of 20). Total 63.\n\n### Payments \u0026 pricing: Uniswap Trading API +5\n\n- KuCoin (35): No machine payment protocol (0). The spot base fee is stated in support articles without login, the futures base rate and the full tier table sit in images or behind script (15 of 20). Market data needs no key, no card is asked for at sign-up (20). A person registers, verifies identity and mints the key in a browser (0). 35.\n- Uniswap Trading API (40): No machine payment protocol on the API's endpoints; the `pay-with-any-token` skill lets an agent pay other services' 402 challenges by swapping, which earns nothing here (0). The API is free, stated in the FAQ and the 16 April 2026 post, and integrator fees are capped at 500 bips (20). No card and no plan (20). A person creates an account in the dashboard to get a key (0). Total 40.\n\n## Score by category\n\n| Category | Weight | KuCoin | Uniswap Trading API | Edge |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% (20 this run) | 45 | 42 | KuCoin +3 |\n| Performance | 10%, pending | pending | pending | not scored in this run |\n| Schema \u0026 documentation | 13% (16.2 this run) | 60 | 90 | Uniswap Trading API +30 |\n| Agent ergonomics | 13% (16.2 this run) | 62 | 72 | Uniswap Trading API +10 |\n| Security \u0026 auth | 14% (17.5 this run) | 55 | 63 | Uniswap Trading API +8 |\n| Payments \u0026 pricing | 10% (12.5 this run) | 35 | 40 | Uniswap Trading API +5 |\n| Task success | 10%, pending | pending | pending | not scored in this run |\n| Maintenance \u0026 community | 7% (8.8 this run) | 73 | 88 | Uniswap Trading API +15 |\n| Transparency \u0026 trust | 7% (8.8 this run) | 54 | 55 | Uniswap Trading API +1 |\n| Negative events | ≤15 | 0 | 0 | |\n| **Total** | | **53.9 · D** | **63.3 · B** | |\n\n## Facts side by side\n\n| Fact | KuCoin | Uniswap Trading API |\n| --- | --- | --- |\n| Kind | HTTP API | HTTP API |\n| Vendor | KuCoin | Uniswap Labs |\n| Hosted endpoint | no (local only) | no (local only) |\n| Transports | | |\n| Auth | API key | API key |\n| Pricing | Pay per use | Free |\n| x402 | no | no |\n| Licence | none | The Trading API is a proprietary hosted service under Uniswap Labs' API Terms of Use, which we couldn't read; the SDKs and the uniswap-ai skills are MIT.

It runs no MCP server, has no sandbox, status page or OpenAPI file, and its terms name no legal entity.\n\n**Uniswap Trading API.** The Trading API is free, documented by an OpenAPI file with stable error codes, holds no keys since the caller signs every swap, and posts sunset notices 30 days ahead. There is no official MCP server, status page or sandbox, the key is a plain header secret at 6 requests a second, and the API terms refused our reader.\n\n## Before you call either\n\n### KuCoin\n\n1. Mint a key with General only for research; add Spot or Futures only with an IP allow-list, since unbound trading keys are disabled after 30 days of inactivity\n2. Send a UUID clientOid on every order and keep it for the retry, and read the order back by clientOid before placing again\n3. Budget requests by weight against gw-ratelimit-remaining and sleep for gw-ratelimit-reset milliseconds on 429000; sub-accounts share the pool\n4. There is no sandbox, so rehearse with the smallest order size on a dedicated sub-account\n5. Use the UTA V2 endpoints and hosts; the Classic API loses endpoints without notice, as the margin credit endpoints did on 21 October 2026\n\n### Uniswap Trading API\n\n1. Call `/check_approval` first, then `/quote`; if `permitData` is non-null sign it as EIP-712 and send `signature` and `permitData` together to `/swap` or `/order`, never one without the other\n2. Route on the quote's `routing`: `CLASSIC`, `WRAP`, `UNWRAP` and `BRIDGE` go to `/swap`, `DUTCH_V2`, `DUTCH_V3` and `PRIORITY` to `/order`, `CHAINED` to `/plan`\n3. Refresh any quote older than 30 seconds before broadcasting, and on 429 pause every request from the key before retrying\n4. Retry unchanged only on `UpstreamTimeoutError`; `NoRouteFoundError` and `QuoteAmountTooLowError` need a different amount, token or `protocols` list\n5. Send `X-Agent-Info` with `decision_origin: autonomous` and keep `x-api-key` server-side\n\n## Questions\n\n### Which is better for AI agents, KuCoin or Uniswap Trading API?\n\nUniswap Trading API scores 63.3 (B) on agent readiness against KuCoin's 53.9 (D), and leads in 6 of 7 scored categories.\n\n### Do KuCoin and Uniswap Trading API need an API key?\n\nBoth need an API key.\n\n### Can an agent call KuCoin and Uniswap Trading API without installing anything?\n\nNo hosted endpoint is listed for KuCoin.
