Why the edge:
- Maintenance & community, OKX API +53: Bitstamp API 28 (Read as a closed service. The last dated API change is 28 August 2026, 67 days before the check (20). Only one dated entry in the last 90 days, after 1 July and 12 June (0). No public repository or issue tracker, support pages did not load and support.bitstamp.net did not resolve; a changelog exists (8 of 25). No official SDKs and no MCP registry presence of Bitstamp's own (0). No package to assess (0). 20 + 0 + 8 + 0 + 0 = 28.); 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.)
- Schema & documentation, OKX API +22: Bitstamp API 51 (No OpenAPI or other machine-readable contract was found on the API page or elsewhere (0). No llms.txt or Markdown docs (0). The single documentation page describes each endpoint's purpose and parameters, with notes such as the 10-second cache on open orders and the Travel Rule fields, but not when to use one endpoint over another (14 of 20). Parameters are typed with enumerations (margin mode CROSS or ISOLATED, margin multiplier 1 to 25, order types) and required fields marked (11 of 15). Signing examples in Python, Java and C++, and error families with numbered codes and explanations (13 of 15). Version v2 in the path and header, a dated changelog from 7 April 2023 to 28 August 2026, and a 410.001 code for deprecated endpoints, with no stated notice period (13 of 15). 0 + 0 + 14 + 11 + 13 + 13 = 51.); 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.)
- Agent ergonomics, OKX API +19: Bitstamp API 58 (Graded on the REST API. Order book grouping and transaction time windows size responses, but there is no field selection and no MCP surface (15 of 25). Offset, limit, since and sort on transaction history, `until_id` windows on order-data replay (14 of 20). `response_code` and `response_explanation` name the failure, such as 400.009 insufficient balance, 403.004 trading blocked and 500.025 insufficient liquidity (16 of 20). No idempotency, since `client_order_id` duplicates are allowed since November 2023 and the docs say only to check the order id after a timeout; the kill switch limits damage (8 of 20). Few required parameters, but no official SDK in any language (5 of 15). 15 + 14 + 16 + 8 + 5 = 58.); 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.)
- Transparency & trust, OKX API +9: Bitstamp API 53 (The editorial half. A closed service whose terms of use loaded empty for our reader, so the licence and clauses are unknown (8 of 30). The privacy policy loaded empty, so retention and data handling are unchecked (0 of 30). A 410.001 code marks deprecated endpoints and the changelog records replacements such as `trading-pairs-info` by `markets`, with no notice period stated (8 of 20). Subprocessors and data locations are in the unread privacy policy (0). 8 + 0 + 8 + 0 = 16.); 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.)
- Security & auth, OKX API +8: Bitstamp API 60 (Revocable HMAC-SHA256 keys with per-endpoint permissions, an IP allow-list, single-use nonces, a timestamp window, sub-account scoping and a one-call kill switch for every key; no key expiry found (24 of 30). Permissions are chosen per endpoint and withdrawals can need Travel Rule address verification, but whether a withdrawal address allow-list exists sits in the unread account settings and no confirmation step is documented for API withdrawals (14 of 20). The API returns exchange data, not third-party text (10). No per-key audit log found; the account's transaction history is the record (4 of 15). security.txt names HackerOne's Robinhood programme but expired on 12 July 2026; no certification page was readable (8 of 20). 24 + 14 + 10 + 4 + 8 = 60.); 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.)
