title: rest api#

hydrant's REST API is split into public endpoints (safe to expose) and management endpoints (keep private). see getting started for guidance on what to expose.

public#

  • GET /stream: subscribe to the event stream. query params: cursor (optional, start from a specific event ID).
  • GET /stats: get stats about the database (counts of repos, records, events; sizes of keyspaces on disk).
  • GET /health / GET /_health: health check.

management#

  • filter: NSID filter configuration
  • ingestion: enable/disable crawler, firehose, backfill at runtime
  • crawler: crawler source management
  • firehose: firehose source management
  • pds: rate-limit tier assignments
  • repos: explicit repository tracking, resyncing, untracking
  • database: compression training, compaction
