No status page found; status.mexc.com does not resolve and llms.txt points to a maintenance-updates feed (0). No readable incident history (5). Rate limits documented with numbers, 300 weight per 10 seconds per IP, 500 per UID, 12 order requests a second per UID, 100 WebSocket messages a second (15). 429 and 418 carry Retry-After with ban lengths stated, a 5xx is to be treated as unknown rather than failed, an order-test endpoint exists, and newClientOrderId is optional with no idempotency promise (13 of 15). No SLA found (0). Spot and futures are generally available, futures order placement having reopened on 31 March 2026 after being closed since July 2022 (10). 0 + 5 + 15 + 13 + 0 + 10 = 43.\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 +13\n\n- MEXC API (64): Graded on the REST API with the CLI's MCP mode. Responses take limit parameters and the MCP read-only market subset is 22 tools, but a full spot MCP category lists 123 tools (15 of 25). startTime, endTime and limit on history, symbol filters on open orders (14 of 20). Numeric codes with messages, a 30035 order-limit code added 23 October 2026, 5xx guidance (14 of 20). newClientOrderId is optional with no idempotency guarantee; the CLI adds --dry-run and a confirmation step (10 of 20). Few required parameters; SDKs in five languages whose repository was last pushed in February 2024 (11 of 15). 15 + 14 + 14 + 10 + 11 = 64.\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: MEXC API +11\n\n- MEXC API (31): No machine payment protocol (0). Fees published without login on MEXC's own fee guide (20 October 2026) and a 2024 announcement, with a separate API futures schedule; the fee page itself is drawn by script (16 of 20). Public market data needs no key or card; trading needs a verified and funded account. Judgement call (15 of 20). A person must sign up in a browser, and futures need identity verification (0). 0 + 16 + 15 + 0 = 31.\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 +9\n\n- MEXC API (64): No OpenAPI found; a Postman collection and the CLI's 25 capability reference files are the nearest machine-readable contract (5 of 25). llms.txt on mexc.com, written for assistants and pointing at the API docs and legal pages (7 of 10). Per-endpoint pages with purpose, parameters and permissions, without when-not-to-use guidance (13 of 20). Typed parameters with enums for order types, statuses and intervals (11 of 15). Examples on each endpoint and a separate error-code page with numeric codes and messages (13 of 15). Versioned API (v3) with a dated changelog of 72 entries to 23 October 2026 (15). 5 + 7 + 13 + 11 + 13 + 15 = 64.\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### Maintenance \u0026 community: OKX API +6\n\n- MEXC API (75): Read as a closed service. Last dated change 23 October 2026 in both the spot and futures logs (30). Spot entries on 14 August, 24 August, 11 September and 23 October 2026, futures on 1 September, 11 September, 19 October and 23 October (20). An API support Telegram group, a ticket form and dated changelogs; GitHub issues not read (10 of 15). The official SDK repository was last pushed in February 2024 while the CLI is current (10 of 15). The CLI ships platform binaries with no dependencies and no public repository or CI; the SDK is stale (5 of 10). 30 + 20 + 10 + 10 + 5 = 75.\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 | MEXC API | OKX API | Edge |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% (20 this run) | 43 | 65 | OKX API +22 |\n| Performance | 10%, pending | pending | pending | not scored in this run |\n| Schema \u0026 documentation | 13% (16.2 this run) | 64 | 73 | OKX API +9 |\n| Agent ergonomics | 13% (16.2 this run) | 64 | 77 | OKX API +13 |\n| Security \u0026 auth | 14% (17.5 this run) | 65 | 68 | OKX API +3 |\n| Payments \u0026 pricing | 10% (12.5 this run) | 31 | 20 | MEXC API +11 |\n| Task success | 10%, pending | pending | pending | not scored in this run |\n| Maintenance \u0026 community | 7% (8.8 this run) | 75 | 81 | OKX API +6 |\n| Transparency \u0026 trust | 7% (8.8 this run) | 58 | 62 | OKX API +4 |\n| Negative events | ≤15 | 0 | 0 | |\n| **Total** | | **56.3 · C** | **64.3 · B** | |\n\n## Facts side by side\n\n| Fact | MEXC API | OKX API |\n| --- | --- | --- |\n| Kind | HTTP API | HTTP API |\n| Vendor | MEXC (Comoros) Ltd | OKX |\n| Hosted endpoint | no (local only) | no (local only) |\n| Transports | stdio | 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).

There is no sandbox or status page, API futures orders pay a higher fee schedule, and the user agreement excludes the US, UK, EU members and others.\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### MEXC API\n\n1. Use a key limited to SPOT_ACCOUNT_READ and SPOT_DEAL_WRITE, the pairs you trade and your IP addresses; keys without a linked IP expire after 90 days\n2. Start the MCP server as `mexc mcp spot --read-only` unless the task trades, and never pass `--yes`; orders and transfers wait for the person's confirmation\n3. Call POST /api/v3/order/test before a live order, since there is no sandbox\n4. On 429 or 418 wait for Retry-After; order placement and cancellation share 12 requests a second per UID, and repeated breaches ban the IP for up to 3 days\n5. Treat a 5xx on an order as unknown, not failed, and query the order before retrying; set newClientOrderId so the order can be found\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, MEXC API or OKX API?\n\nOKX API scores 64.3 (B) on agent readiness against MEXC API's 56.3 (C), and leads in 6 of 7 scored categories. MEXC API leads on payments \u0026 pricing.\n\n### Do MEXC API and OKX API need an API key?\n\nBoth need an API key.\n\n### Can an agent call MEXC API and OKX API without installing anything?\n\nMEXC API runs on your own machine, with no hosted endpoint listed. 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/mexc-vs-okx.json, and with the fewest tokens: https://www.anchorterminal.com/compare/mexc-vs-okx.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"mexc\", \"b\": \"okx\"}`.
