speedrun.io API — Release Notes

Notable Differences from speedrun.com's API

Guest and profile endpoints removed.
Certain filter and sort options have been flagged for future versions or removed.
HTTP 500 for run offsets greater than 10k have been fixed.
Users are discovered through run submissions. An account with no submitted runs is not currently indexed.

Embedding (?embed=) is currently disabled by design. Testing showed vast format inconsistencies and real instability for records with bulk, uncapped entries. Our in-house bandwidth-limited version is planned for the next /src revision which should handle most use cases. An optimized, paged and fully reworked endpoint will be available in /v1 which will be the recommended solution.

Multi-field filtering, pagination, and response formats otherwise match or extend speedrun.com's API. See the SRC Mirror docs for the full list of supported filters and sort fields per endpoint. Check the changelog below for notable additions, bug fixes and limitations.
