Run Cebu API Documentation
The Run Cebu Events API exposes public race listings and scoped write operations for approved maintainers and agents. Public reads require no credentials and return JSON. Write operations require an API key in the X-API-Key header.

Versioning: the current stable API contract is 2026-08-27. Agents may send Run-Cebu-API-Version: 2026-08-27 to pin documented behavior. Breaking changes use a new version value and deprecated versions or operations publish Deprecation and Sunset headers before removal.
Rate limit policy: public reads publish RateLimit-Policy and RateLimit headers. Clients should back off when limits are low and cache stable event metadata when appropriate.
Error format: API errors use RFC 9457 problem details with application/problem+json.
