Developers & API

Everything an agent or integration needs to build on TrophyCoach, in one place. The Agent API is versioned by date (current: 2026-08-24), returns JSON on every error, and reports its rate limit (300 requests per 60s per key) in response headers. Every public page is also available as markdown via Accept: text/markdown or a .md URL suffix.
