Why the edge:
- Payments & pricing, Exa API + MCP +60: Exa API + MCP 90 (x402 on POST /search and /contents, USDC on Arc, Base, World Chain or Solana, including Circle Gateway nanopayments, not on answer, Agent runs, monitors or Websets, so partial (30). Per-call prices published without login, $0.004 for `lite` (and legacy `instant`) to $0.015 for legacy deep-reasoning per search (20). $10 a month and a $10 onboarding bonus, and the pricing page now states "No payment method required" (20). An agent can pay by x402 with no account, and the hosted MCP works anonymously within rate limits (20).); NewsCatcher 30 (No x402, MPP or L402 (0). Credit prices per call published without login, and credits cost $1 per 1,000 through top-ups from $25 (20). 10,000 free credits every 30 days on a $0 plan, and the first top-up moves an account to pay as you go. No page says whether a card is needed to open the free plan, so half (10). A person signs up in the platform in a browser to get a key (0). NewsMCP's keyless tier belongs to a separate product and isn't counted. 0 + 20 + 10 + 0 = 30.)
- Transparency & trust, NewsCatcher +18: Exa API + MCP 61 (The MCP server is MIT and the API is closed with published terms (20). The privacy policy, still dated 29 June 2026 on 21 October, says query data is used to train and fine-tune Exa's models and states no retention period. Zero data retention needs a sales conversation, and the DPA sits in the trust centre (12). Dated deprecations in the changelog, such as the `pdf`, `github` and `tweet` categories on 23 July and the `instant`, `fast` and `deep-reasoning` search types made legacy on 19 October, with no removal dates (12). The MCP server, hosted and on npm, sends usage events to Agnost (api.agnost.ai) with no mention in the README, no opt-out flag, and no named subprocessor list in the privacy policy, unchanged on main on 21 October (0).); NewsCatcher 79 (The API is closed under terms of 2 November 2026 naming NewsCatcher, Inc., and the MCP server is MIT, so between the two bands (20 of 30). The terms say inputs and generated data are not used to train models, a DPA applies automatically, and the privacy policy gives retention periods (server logs 7 days, API logs with query text 90 days, then archived indefinitely, billing records about seven years). They agree with each other, but indefinite archives of query logs hold it back (22 of 30). The terms promise 30 days' email notice before a paid product or API version is discontinued, with refunds of unused credits, and the v3 News API has a migration guide (15 of 20). A sub-processor list dated 2 November 2026 with each provider's location and the data it handles. The MCP repository deploys to Vercel and can send pseudonymised analytics to PostHog, and neither appears on the list (16 of 20). 20 + 22 + 15 + 16 = 73.)
- Agent ergonomics, Exa API + MCP +12: Exa API + MCP 96 (On a keyless connection two tools are on by default, `web_search_exa` and `web_fetch_exa`, about 1,250 characters of descriptions between them. Since the 19 October commit on main, `agent_run` (about 500 characters plus a larger input schema) is also on by default when the user supplies a key, though the README still lists it as optional. `?tools=` turns on `web_search_advanced_exa` and picks the set (25). `numResults`, `maxCharacters`, highlights instead of full text, category, domain and date filters, and in `web_search_advanced_exa` the `lite` type (20). The error-codes page lists codes, and the MCP server rewrites a 429 into a message about the free tier and keys and now passes search notices to the model. Errors reach the model as text rather than a code (16). Every tool sets `readOnlyHint`, `destructiveHint: false` and `idempotentHint` (false on `agent_run`), and the server retries transient errors twice (20). Only `query` is required. Python and TypeScript SDKs (15).); NewsCatcher 84 (15 MCP tools in four toolsets, chosen per connection with `?tools=`, and tools return compact text rather than the full JSON. 15 for 11 to 30 tools plus 7 for toolsets (22 of 25). `limit`, `search_window`, effort, language, country, publisher, coverage and content-type filters, sorting, and paging on `/articles`; agent tables come back up to 200 rows at a time over MCP (20). Every status is documented with whether to retry; the agent returns stable `code` values, while the News API body has a `status_code` and a message meant for people (17 of 20). Every tool carries readOnlyHint and idempotentHint, writes carry destructiveHint, `start_research` has a free `dry_run`, and refused or failed calls aren't charged. No idempotency key for starting runs (17 of 20). Only `q` is required, with medium effort and a 7-day window as defaults. No official SDK for the current API was found; the docs show raw HTTP in three languages (8 of 15). 22 + 20 + 17 + 17 + 8 = 84.)
- Maintenance & community, Exa API + MCP +12: Exa API + MCP 88 (exa-py and exa-js 2.27.0 tagged on 30 October 2026, after 2.26.0 and the API changelog entry of 19 October (30). 14 tags of each SDK from v2.17.0 (7 August) to v2.27.0 (30 October), and changelog entries on 28 August, 24 September and 19 October (20). 13 open MCP issues and pull requests merged on 2, 6, 7 and 19 October per the 21 October check, with pull requests merged on 27 and 28 October in the clone; reply times unread because GitHub's pages refuse us (15). Official registry entry ai.exa/exa under Exa's own domain, latest 3.4.1 (published 23 September), and current Python and TypeScript SDKs (15). CI typechecks and tests the MCP server on every push. The npm package (3.4.2, 6 October, per the 21 October check) ships from a workflow without git tags, and package.json on main is still 3.4.2 on 1 November (8).); NewsCatcher 76 (Read for a closed service, with the MCP repository read as code. News API 1.1.0 and Agent 1.5.0 on 4 November 2026, MCP server 0.1.0 on 6 November and v3 News API 3.25.0 on 6 November (30). In the 90 days from 8 August, the 30 October launch, News API 1.1.0, Agent 1.5.0, MCP 0.1.0 and v3 releases 3.19.0 to 3.25.0 (20). Public dated changelogs, support by email and Pylon, and a security policy with a 3-business-day target. The MCP repository is a day old, so there are no issues to judge (10 of 15). The CatchAll MCP server is in the official registry under the verified namespace com.newscatcherapi, but the new server isn't, and no official SDK for the current API was found; the Enterprise APIs list libraries (8 of 15). The MCP repository runs its test suite in CI with a read-only token; pass state not read (8 of 10). 30 + 20 + 10 + 8 + 8 = 76.)
- Reliability, Exa API + MCP +10: Exa API + MCP 77 (Instatus page at status.exa.ai with Search API, Exa MCP, Agents API and Websets components and dated history (20). In the 90 days to 1 November, history/1 shows the Search API's 1-minute blip (16 September), a 1 hour 24 minute latency incident (18 September) and 2 hours 21 minutes of elevated latency with some failed requests (21 September), and the Agents API's 25 minutes of runs failing to start (18 September, labelled major) and 4 hours 56 minutes in which 'some agent runs may fail to start or complete' (21 to 22 September). August is per the 21 October check, not re-read on 1 November (history/2 answers 404 again), with a 10-minute Search API major outage on 14 August and a 53-minute latency incident. No notices in October or November. By this run's reading each hit one product or a subset of requests and none was an hour of a core API down, so all are minor (20, up from 10, where the 21 to 22 September Agents API incident had been counted as a major). Rate limits published per endpoint, 10 QPS search and answer, 5 QPS deep, 100 QPS contents, 5 QPS and 50 active Agent runs (15). 429 with `Retry-After` when available and exponential backoff advice. We found no idempotency guidance for creating Agent runs, which cost money (12). No SLA found. The pricing page lists "Enterprise SLAs" on the contract plan, with no terms published (0). Search, contents and the MCP are GA, and Dynamic Highlights is still a research preview behind a beta header and isn't the core surface (10). 20 + 20 + 15 + 12 + 0 + 10 = 77.); NewsCatcher 67 (Read with the hosted lines, for the News API, the agent and the hosted MCP server. status.newscatcherapi.com (Hyperping) shows one News API component with 99.820% uptime from August to November 2026 and an incident history. The agent and the MCP server have no component of their own (20). In the 90 days from 8 August, one incident, on 1 September 2026, when the vendor wrote that for about four hours a higher-than-usual number of requests to the production News API timed out because of one client's queries. Read as one major (10). Rate limits published per plan, 1 request a second free and up to 10 on pay as you go, with exact limits from the free `GET /subscription` (15). 429 carries Retry-After with instructions to retry the same request, 503 carries Retry-After, and failed or refused requests are not charged. Agent runs and monitor creation have no idempotency keys (12 of 15). An uptime SLA exists only in signed Enterprise agreements; none is published (0). Generally available since 30 October 2026, with OAuth for the MCP server announced as coming soon (10). 20 + 10 + 15 + 12 + 0 + 10 = 67.)
- Schema & documentation, NewsCatcher +8: Exa API + MCP 86 (OpenAPI at exa.ai/docs/exa-spec.yaml, re-read on 21 October with the new `lite` type, its accepted parameters and the `warnings` and `notices` response fields, and JSON Schema inputs on every MCP tool (25). llms.txt and Markdown docs (10). `web_search_exa` tells the model how to phrase a query and when to follow up with `web_fetch_exa`, and deprecated tools name their replacement. The `agent_run` description on the main branch since 19 October says it isn't for a single lookup or a known URL and names the sibling tools, but that commit isn't in npm 3.4.2 and we couldn't confirm the hosted server runs it, so the line stays where it was. Nothing else says when not to use a tool (15). Inputs coerce loosely. `numResults` is described as 1 to 100 but the schema has no bounds, and bad numbers fall back to defaults silently. On the API, `lite` rejects an unsupported parameter with a 400 that names it, and ignored fields such as `startCrawlDate` now come back as `IGNORED_FIELD` warnings (10). An error-codes page and examples on every endpoint page (13). Dated changelog with deprecations, the latest entry 19 October. The MCP repository has no tags, so versions show only in package.json and the registry (13).); NewsCatcher 94 (OpenAPI 3.1 for the News API (version 1.3.9, 4 paths) and the agent (version 1.5.1, 33 paths), linked from llms.txt, and typed JSON Schema on every MCP tool through Pydantic (25). llms.txt, a Markdown copy of every page and a docs MCP server (10). MCP tool descriptions say when to use each and which tool to use instead, such as `list_articles` for older news; the REST reference explains each endpoint and the 'Choose an API' page compares them (17 of 20). Inputs are typed with enums for effort, mode and dimensions, length and range limits such as a 500-character query and limit 1 to 100, and required fields marked (13 of 15). Runnable examples in curl, Python and JavaScript, and an error table with retry advice for every status. The agent spec carries no response examples (14 of 15). Versioned APIs with a dated changelog, the latest entries on 4 November 2026, and separate changelogs for the v3 News API and CatchAll (15). 25 + 10 + 17 + 13 + 14 + 15 = 94.)
