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.\n- OKX API (65): Read with the hosted lines on the V5 REST API. okx.com/status is OKX's own page with issue descriptions, maintenance notices and deposit and withdrawal status, but no component history or feed (10 of 20). It lists no incident between 5 August and 3 November 2026; its newest entry is from March 2024, and whether every incident reaches the page cannot be told, so read as clean with a doubt (20 of 30). Rate limits per endpoint, per User ID and per sub-account with numbers, and WebSocket limits (15). Error 50011 on a limit, a clOrdId on orders and a cap of 3 amendments in flight, but no Retry-After or backoff guidance found (10 of 15). No SLA (0). Generally available (10). 10 + 20 + 15 + 10 + 0 + 10 = 65.\n\n### Agent ergonomics: OKX API +15\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- OKX API (77): limit parameters on books, candles and history, and in the kit --modules and --read-only narrow 170 tools to the three default modules; no field selection (17 of 25). after, before and limit cursors on history endpoints (18 of 20). Numeric codes with messages, such as 51020 for an invalid quantity, and the kit returns a structured error block with code, message and endpoint (17 of 20). clOrdId on orders, batch endpoints and a cap of 3 amendments in flight; the kit sets readOnlyHint on query tools but destructiveHint false on order tools and has no idempotency key (13 of 20). python-okx, the CLI and a demo profile, with passphrase and HMAC signing on every private call (12 of 15). 17 + 18 + 17 + 13 + 12 = 77.\n\n### Payments \u0026 pricing: KuCoin +15\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- OKX API (20): No machine payment protocol (0). The fee table loads by script and the fee FAQ defers to the logged-in view, so no rate was read (0 of 20, unchecked). Public market data and demo trading need no funded account or card (20). A person signs up, verifies and mints a key (0). 0 + 0 + 20 + 0 = 20.\n\n### Schema \u0026 documentation: OKX API +13\n\n- 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.\n- OKX API (73): No OpenAPI file was found in the V5 docs; the kit's tool definitions are typed TypeScript with annotations, and the organisation has an undescribed ai-builder-openapi-md repository we did not read (12 of 25). okx.com/llms.txt exists and links the API and Agent Trade Kit pages, though the V5 docs have no Markdown twins (5 of 10). Each endpoint states its rate limit, rule, parameters and notes (15 of 20). Enums for ordType, tdMode and instType with required flags (12 of 15). Request and response examples per endpoint and an error code list with messages (14 of 15). A dated changelog with an upcoming-changes section that labels breaking changes and dates sunsets (15). 12 + 5 + 15 + 12 + 14 + 15 = 73.\n\n### Security \u0026 auth: OKX API +13\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- OKX API (68): Key, secret and passphrase with Read, Trade and Withdraw permissions, up to 20 bound IPs, revocation in the account, and unbound Trade or Withdraw keys that expire after 14 idle days; no OAuth (28 of 30). Read-only keys, sub-account keys, demo trading, the kit's --read-only flag and its startup check that hides order tools when the key cannot trade, and an API Agreement requiring minimum scope; no confirmation step in the kit (18 of 20). The news and smartmoney modules return third-party text and the docs read give no guidance on treating it as untrusted (5 of 15). An account audit log tool in the kit and usage records for unbound keys in the Security Center, no per-call log (9 of 15).

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- OKX API (81): Read as a closed service with an open-source kit. Changelog entry of 27 October 2026 and kit v1.5.0 on 28 October (30). Changelog entries on 3, 6, 11, 18, 20 and 26 August, 15, 29 and 30 September and 27 October, and kit releases on 20 and 21 August, 1, 7, 14 and 23 September, 19 and 28 October (20). A public changelog, a Telegram community for the kit and GitHub issues whose replies were not read (10 of 15). python-okx is named as the official SDK and the kit is current; the MCP server is not in the official registry (12 of 15). The kit runs CI on push and pull request across Node 18, 20 and 26 with unit tests and coverage (9 of 10). 30 + 20 + 10 + 12 + 9 = 81.\n\n## Score by category\n\n| Category | Weight | KuCoin | OKX API | Edge |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% (20 this run) | 45 | 65 | OKX API +20 |\n| Performance | 10%, pending | pending | pending | not scored in this run |\n| Schema \u0026 documentation | 13% (16.2 this run) | 60 | 73 | OKX API +13 |\n| Agent ergonomics | 13% (16.2 this run) | 62 | 77 | OKX API +15 |\n| Security \u0026 auth | 14% (17.5 this run) | 55 | 68 | OKX API +13 |\n| Payments \u0026 pricing | 10% (12.5 this run) | 35 | 20 | KuCoin +15 |\n| Task success | 10%, pending | pending | pending | not scored in this run |\n| Maintenance \u0026 community | 7% (8.8 this run) | 73 | 81 | OKX API +8 |\n| Transparency \u0026 trust | 7% (8.8 this run) | 54 | 62 | OKX API +8 |\n| Negative events | ≤15 | 0 | 0 | |\n| **Total** | | **53.9 · D** | **64.3 · B** | |\n\n## Facts side by side\n\n| Fact | KuCoin | OKX API |\n| --- | --- | --- |\n| Kind | HTTP API | HTTP API |\n| Vendor | KuCoin | OKX |\n| Hosted endpoint | no (local only) | no (local only) |\n| Transports |  | stdio |\n| Auth | API key | API key |\n| Pricing | Pay per use | Pay per use |\n| x402 | no | no |\n| Licence | none | Proprietary hosted service under OKX's Terms of Service (29 October 2026) and API Agreement (28 July 2026).

It runs no MCP server, has no sandbox, status page or OpenAPI file, and its terms name no legal entity.\n\n**OKX API.** OKX publishes per-endpoint rate limits, Read, Trade and Withdraw key permissions with IP binding, demo trading on the production host, and an MIT MCP server with 170 tools, a read-only flag and a permission check at startup. The fee table and privacy policy were not read, no OpenAPI file was found, and the news tools return third-party text.\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### OKX API\n\n1. Start okx-trade-mcp with --profile demo first, then --read-only on a live key; load only the modules the task needs\n2. Use a sub-account key with Read and Trade only, bound to the agent's IP; an unbound Trade key expires after 14 idle days\n3. Stay under 60 place-order requests per 2 seconds per instrument and at most 3 amendments in flight per order; 50011 means the limit was hit\n4. Send a clOrdId on every order and use the structured error block (code, message, endpoint) to diagnose with read-only tools before retrying\n5. Call us.okx.com or eea.okx.com for US, Australian and EEA accounts; openapi.okx.com does not serve those regions\n\n## Questions\n\n### Which is better for AI agents, KuCoin or OKX API?\n\nOKX API scores 64.3 (B) on agent readiness against KuCoin's 53.9 (D), and leads in 6 of 7 scored categories. KuCoin leads on payments \u0026 pricing.\n\n### Do KuCoin and OKX API need an API key?\n\nBoth need an API key.\n\n### Can an agent call KuCoin and OKX API without installing anything?\n\nNo hosted endpoint is listed for KuCoin. OKX API runs on your own machine, with no hosted endpoint listed.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/kucoin-vs-okx.json, and with the fewest tokens: https://www.anchorterminal.com/compare/kucoin-vs-okx.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"kucoin\", \"b\": \"okx\"}`.
