Bithumb Open API vs Gate

Bithumb Open API 15

No machine payment protocol (0). The fee page timed out on every attempt, so no price is recorded (0 of 20, unchecked). Public market data needs 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 in the browser (0). 0 + 0 + 15 + 0 = 15.

Gate 35

No machine payment protocol (0). The fee page's table loads after login; help centre and learn articles give the VIP 0 spot rates (15 of 20). Market data over REST and the public MCP needs no account and no card (20). A person registers, verifies identity and mints the key or approves the grant in a browser (0). 35.

Bithumb Open API 34

Read with the hosted lines. No status page found on apidocs.bithumb.com or in llms.txt; wallet-status and notices endpoints stand in (0). No readable incident history, though two notices record a public WebSocket interruption and a brief service break (5). Rate limits documented per category with numbers, updated 27 October 2026 (15). A breach is described only as a temporary restriction, with no status code, header or Retry-After, and no client order id or idempotency key is documented; 422 order_not_ready and 500 server_error say to retry later (4 of 15). No SLA found (0). The API is generally available; the MCP server and CLI are at 0.8.5 (10). 0 + 5 + 15 + 4 + 0 + 10 = 34.

Gate 42

Graded with the hosted lines on the API v4 at api.gateio.ws with the hosted MCP beside it. No status page found (status.gate.com does not resolve, the docs link none), so 0 for the page and 5 for no readable history. Rate limits are published per endpoint group with numbers and fill-ratio rules (15). Every response carries X-Gate-RateLimit-Limit, X-Gate-RateLimit-Requests-Remain and X-Gate-RateLimit-Reset-Timestamp, 429 answers with the label TOO_FAST, and spot orders take a user text identifier, but no retry or idempotency guidance is written down (12 of 15). No SLA (0). API v4 and the MCP endpoints are production surfaces (10). 42.

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.

Gate 77

Read as a hosted service with open-source MCP packages. The API changelog's latest entry is 2 November 2026 and gate-skills was pushed 3 November (30). 40 dated changelog entries since 5 August 2026 (20). developer@gate.com, a help centre and issue trackers on gate-mcp and gate-skills, replies not checked (12 of 25). In the official MCP registry under io.github.gateio-dev, a GitHub namespace rather than gate.com, and official SDKs current (10 of 15). The local package has a publish workflow and no test workflow in CI, and its last tag is 16 April 2026 (5 of 10). 77.

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.

Gate 70

No public OpenAPI file was found, though the SDKs are generated and the MCP tools carry typed parameters per the tool reference; the hosted tools' JSON Schema could not be read without a session (12 of 25). The whole REST and WebSocket documentation is downloadable as Markdown and the agent guide is a plain page (10). The tool reference gives one line and the main parameters per tool, the API reference a description per endpoint, no when-not-to-use guidance (12 of 20). Required flags, enums for side, type and time_in_force (11 of 15). Examples per endpoint and a labelled error body with a fixed label list the docs tell you to branch on instead of messages (13 of 15). A versioned changelog, v4.106.177 on 2 November 2026 (12 of 15, since entries are terse). 70.
