Why the edge:
- Maintenance & community, KuCoin +44: Crypto.com Exchange API 29 (Read as a closed service with an open CLI. The last change we could date is cdcx-cli v1.2.6 on 18 June 2026, 138 days before the check, with no commit since; the API changelog is unread (10). No three dated releases in the last 90 days (0). Five of six open items on cdcx-cli, all by collaborators or Dependabot since May, have no comment; the Exchange has a support chat and contact@crypto.com (8 of 25). Not in the official MCP registry and no official SDK beyond the CLI (5 of 15). CI tests on three operating systems with clippy and fmt; the npm wrapper's postinstall downloads the binary and two Dependabot bumps are open (6 of 10). 10 + 0 + 8 + 5 + 6 = 29.); 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.)
- Schema & documentation, KuCoin +18: Crypto.com Exchange API 42 (An OpenAPI spec exists, since cdcx-cli generates its 95 commands and tools from it at run time, but its host (exchange-developer.crypto.com) answered 403 to robots.txt and the spec was not read; the vendor's own tooling is evidence it exists, not of its quality (15 of 25). No llms.txt on crypto.com or the Exchange pages (0). For descriptions, cdcx's tool descriptions come from the spec, which we couldn't read; the Exchange skill documents 52 endpoints in prose (8 of 20). cdcx's README says the tools carry typed parameters and enum validation, a vendor claim not checked against the spec (8 of 15). For examples, the skills and cdcx README carry worked commands, but the API's error codes and response examples sit on the unread host (6 of 15). Versioned path (v1); the API changelog and announcements page could not be read (5 of 15). 15 + 0 + 8 + 8 + 6 + 5 = 42.); KuCoin 60 (No OpenAPI or other machine-readable contract was found; the docs link a Postman workspace and the universal SDK is generated from an internal spec (8 of 25). 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.)
- Agent ergonomics, KuCoin +12: Crypto.com Exchange API 50 (Graded on the REST API as an agent calls it, with the MCP server noted. cdcx serves up to 95 tools, more than 30, but the default serves the `market` group alone and groups are enabled one by one, which is a read-only subset switch (5 + 10 = 15). Pagination and output controls for the API are on the unread docs host; cdcx adds `-o json|table|ndjson` (8 of 20). cdcx returns structured JSON errors and the safety gate names what is missing; the API's own error table is unread (8 of 20). cdcx's tiers (mutate needs `acknowledged: true`, dangerous needs `--allow-dangerous`), `--dry-run` and paper trading give safe rehearsal, though no MCP annotations or API idempotency keys were seen (12 of 20). No official SDK beyond the CLI; defaults in cdcx are sensible (7 of 15). 15 + 8 + 8 + 12 + 7 = 50.); 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.)
- Reliability, Crypto.com Exchange API +5: Crypto.com Exchange API 50 (Read with the hosted lines on the Exchange API at api.crypto.com. status.crypto.com is a Statuspage site with component history (20). Its feed for 18 August to 3 November 2026 has 25 entries; the Exchange is named in two, an 11-minute database upgrade on 18 August and a one-hour balance display issue on 6 October, while the longer disruptions (Android login on 1 and 5 October, card 3DS on 23 September, Main App predictions on 3 November) are App incidents. There is no Exchange API component, so the record may be incomplete. Minor only (20). Rate limits are documented on exchange-docs.crypto.com, which answered 403 to robots.txt and was not read (0, unchecked). 429 handling and client order ids are on the same host (0, unchecked). No SLA found (0). Generally available (10). 20 + 20 + 0 + 0 + 0 + 10 = 50.); KuCoin 45 (Graded with the hosted lines on the API at api.kucoin.com. No status page found (status.kucoin.com does not resolve, the docs link none), so 0 for the page and 5 for no readable history. Rate limits are published per VIP level with per-endpoint weights and IP limits for public endpoints (15). Every response carries gw-ratelimit-limit, gw-ratelimit-remaining and gw-ratelimit-reset, 429000 is documented with a wait rule, and orders take a clientOid the docs recommend as a UUID (15). No SLA (0). The UTA V2 API is the production surface (10). 45.)
- Payments & pricing, Crypto.com Exchange API +5: Crypto.com Exchange API 40 (No machine payment protocol (0). Spot fee tiers published without login, 0.25% maker and 0.50% taker at Level 1 (20). The API is free, public market data needs no key, UAT and paper trading need no money (20). A person must sign up in a browser with identity checks and mint the key (0). 0 + 20 + 20 + 0 = 40.); 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.)
