Why the edge:
- Schema & documentation, Bithumb Open API +24: Bithumb Open API 64 (No OpenAPI found; the reference is a readme.io site with Markdown twins, and the MCP tool schemas weren't read since the server's source isn't published (5 of 25). llms.txt on apidocs.bithumb.com (10). Reference pages state purpose and the skills say when to use each module and when not to (15 of 20). Typed parameters with enums for side, order type and time in force (10 of 15). Examples in several languages and an error-code page with names, statuses and meanings (12 of 15). Versions per endpoint (v1, v2, v2.1.5) and notices with effective dates (12 of 15). 5 + 10 + 15 + 10 + 12 + 12 = 64.); HTX trading API 40 (No OpenAPI or other machine-readable contract found in the docs or the GitHub accounts (0). No llms.txt on htx.com, and the readable reference is a static page (0). Each endpoint states its purpose and parameters, without when-to-use guidance (12 of 20). Parameter tables carry types, required flags and enums for order types and states (10 of 15). Request and response examples throughout and error-code tables with messages (11 of 15). Versions v1 and v2 are mixed in one reference whose last changelog entry is 24 June 2022, while HTX's newer docs on htx.com couldn't be read (7 of 15). 0 + 0 + 12 + 10 + 11 + 7 = 40.)
- Transparency & trust, Bithumb Open API +22: Bithumb Open API 47 (The editorial half. A closed service whose terms couldn't be read (timeouts and a title-only page); the kit is MIT with a disclaimer naming Bithumb Co., Ltd. (10 of 30). No privacy policy read (0 of 30, unchecked). Dated retirement of WebSocket Private v1 and effective dates on breaking notices (14 of 20). No subprocessor or data-location statement read (0 of 20). 10 + 0 + 14 + 0 = 24.); HTX trading API 25 (The editorial half. A closed service whose user agreement exists but couldn't be read (script-drawn pages), so the licence clarity is unknown rather than unclear (10 of 30). The privacy policy was not read (0 of 30, unchecked). The testnet shutdown and the 2022 changelog entries are dated, with no deprecation policy (5 of 20). No subprocessor or data-location statement read (0 of 20). 10 + 0 + 5 + 0 = 15.)
- Maintenance & community, Bithumb Open API +12: Bithumb Open API 69 (Read as a closed service. Rate limits updated 27 October 2026 and the ticker cap effective 13 October 2026 (30). Batch orders 20 August, Private v1 retired 30 September, the ticker cap 13 October and the limits page 27 October 2026 (20). A phone support line, dated notices and a GitHub repository with no open issues and one commit; replies not observed (9 of 15). The MCP server is not in the official MCP registry and there is no SDK; the CLI and MCP packages are current (5 of 15). The MCP package depends only on @modelcontextprotocol/sdk ^1.26 on Node 18, with no public source or CI (5 of 10). 30 + 20 + 9 + 5 + 5 = 69.); HTX trading API 57 (Read as a closed service. The readable changelog ends on 24 June 2022, but the official contract SDKs were pushed on 21 October 2026 and the spot SDKs in April and July 2026, so the API surface is still being maintained; judgement call (20 of 30). SDK pushes on 30 July, 23 August and 21 October 2026 are commits, not releases (10 of 20). A Telegram group for API support and a support centre, neither tested; GitHub issues not read (8 of 15). Official SDKs in five languages (15). No CI seen, dependencies not checked (4 of 10). 20 + 10 + 8 + 15 + 4 = 57.)
- Security & auth, Bithumb Open API +9: Bithumb Open API 60 (Keys scoped to chosen permissions, mandatory registered IPs, one-year expiry, a JWT per request and a key-list endpoint with expiry (26 of 30). Read-only keys, `--read-only` on the MCP server, per-profile read_only on the CLI, a second factor on KRW deposits and withdrawals, and skills that refuse to switch profiles to bypass read-only; nothing server-side confirms an order (16 of 20). The API returns exchange data and the disclaimer warns about prompt injection through third-party plugins (11 of 15). A local audit log for CLI and MCP calls and a key-list endpoint; no server-side per-call log (7 of 15). security.txt timed out and no disclosure policy, bug bounty or certification was found (0 of 20, security.txt unchecked). 26 + 16 + 11 + 7 + 0 = 60.); HTX trading API 51 (HMAC-signed keys with Read, Trade and Withdraw permissions, sub-user keys without Withdraw, up to 20 bound IPs, revocation in the account and a 90-day expiry without IP binding. The AccessKeyId and the HMAC signature travel as query parameters; the secret does not, so no deduction for a secret in the URL (24 of 30). Read-only keys and withdraw-free keys exist; no server-side confirmation for orders or withdrawals (14 of 20). The API returns the exchange's own data, no untrusted content (10). No per-call log or key-use history found for the operator (3 of 15). No security.txt, disclosure policy or certification found on the pages that loaded (0 of 20). 24 + 14 + 10 + 3 + 0 = 51.)
