Why the edge:
- Reliability, OKX API +23: 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.); Upbit Open API 42 (Read with the hosted lines. No status page found on docs.upbit.com or in llms.txt; a wallet-status endpoint and an announcements stream stand in (0). No readable incident history (5). Rate limits documented with numbers per group, per IP and per pocket, updated 7 October 2026 (15). 429 then 418 with a stated block length and a Remaining-Req header, an order-test endpoint and a self-match-prevention default; an order identifier for safe retries was not checked (12 of 15). No SLA found (0). Generally available (10). 0 + 5 + 15 + 12 + 0 + 10 = 42.)
- Security & auth, OKX API +9: 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). No security.txt; SECURITY.md with security@okx.com and GitHub private advisories; certifications and a bounty not read (8 of 20). 28 + 18 + 5 + 9 + 8 = 68.); Upbit Open API 59 (Keys limited to chosen functions, a mandatory public IPv4 allow-list, a JWT per request with a fresh nonce, keys listed with expiry through the API, and a withdrawal safe-lock on by default (27 of 30). Read-only keys, the default withdrawal lock lifted only in the app, and skills that require a typed CONFIRM before writes (17 of 20). The API returns exchange data and announcements, no third-party content (10 of 15). An API key list endpoint; no per-call log for the operator (5 of 15). No disclosure policy, bug bounty or certification found; security.txt on upbit.com could not be fetched under its robots.txt (0 of 20). 27 + 17 + 10 + 5 + 0 = 59.)
- Transparency & trust, OKX API +8: OKX API 62 (The editorial half. A closed service with terms that name the contracting entities by region and an API Agreement for agents; the kit is MIT (17 of 30). The privacy policy was not read (5 of 30). The changelog dates sunsets and labels breaking changes, such as port 8443 on 31 October and 16 November 2026 (16 of 20). No subprocessor or data-location statement read; the MCP server is local and its npm package runs a postinstall script whose purpose we did not trace (0 of 20). 17 + 5 + 16 + 0 = 38.); Upbit Open API 54 (The editorial half. A closed service whose user and Open API terms could not be fetched under upbit.com's robots.txt, and whose SDK licence page calls the SDK material not open source while the repositories carry Apache-2.0 (8 of 30). The developer centre's privacy policy names Dunamu Inc., gives retention periods and names Zendesk in Japan; the main privacy policy was not read (14 of 30). Notices with effective dates, including the path-format change and the deprecated Remaining-Req min field (12 of 20). Zendesk and Google Analytics named with a location for the developer centre only (8 of 20). 8 + 14 + 12 + 8 = 42.)
- Schema & documentation, OKX API +7: 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.); Upbit Open API 66 (No OpenAPI found; the reference is a readme.io site with a Markdown twin of every page (5 of 25). llms.txt on docs.upbit.com and a kr/llms.txt index (10). Each reference page states what the endpoint does, its group and its errors, with warnings such as market_offline after maintenance (14 of 20). Typed parameters with enums for order type, side and time in force and required flags (11 of 15). Recipes in Python, Java and Node.js and an error format of error.name and error.message with HTTP statuses (13 of 15). Feature versions in page histories (v1.6.1) and dated notices with effective dates, no single API version (13 of 15). 5 + 10 + 14 + 11 + 13 + 13 = 66.)
- Agent ergonomics, OKX API +7: 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.); Upbit Open API 70 (Graded on the REST API with the CLI. Candle counts, list limits and the CLI's --max-items and --transform size responses (16 of 25). Paging and filters on orders and history (15 of 20). error.name codes to branch on, which the November 2026 notice tells clients to use, and 418 with its block length (15 of 20). An order-test endpoint and a CONFIRM gate in the skills; an order identifier for idempotent placement was not checked (11 of 20). Few required parameters, SDKs in three languages and a CLI, but keys need the PC web site and a registered IP (13 of 15). 16 + 15 + 15 + 11 + 13 = 70.)
- Payments & pricing, OKX API +5: 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.); Upbit Open API 15 (No machine payment protocol (0). The fee schedule is on upbit.com, which disallows every crawler path, so no price is recorded (0 of 20, unchecked). Public quotation endpoints need no key, card or account; trading needs a verified Korean account. Judgement call (15 of 20). A person must sign up, pass identity checks and issue keys on the PC web site (0). 0 + 0 + 15 + 0 = 15.)
