m4t.tf developers
m4t.tf is machine-readable. Every page is served as HTML or markdown, and every resource below is an unauthenticated GET — there are no API keys. An MCP server is also published at /mcp.

Rate limits
Every page and resource is unmetered. POST /ask and the ask tool on POST /mcp are metered at 20 requests per minute per client and return 429 Too Many Requests with Retry-After once past it. Metered responses carry RateLimit, RateLimit-Policy, RateLimit-Limit, RateLimit-Remaining, and RateLimit-Reset headers; a 429 adds Retry-After.
Errors
Failures follow your Accept header as application/problem+json, markdown, or HTML, and carry a stable code and resolution.
Versioning
Send API-Version to declare the compatibility version you expect; the current version is 1. Deprecated resources carry Deprecation and Sunset headers until they retire.
The OpenAPI 3.1 document at /openapi.json describes the whole interface, and /llms.txt indexes everything the site publishes.
