Initial public release of the Circa API.

  • REST endpoints: /me, /processes, /processes/pulled, /materials, /materials/pulled, /datapoints/pull.
  • GraphQL endpoint at /graphql with full feature parity.
  • API key authentication via x-api-key. Keys come in live (circa_live_…, hashed, shown once) and test (circa_test_…, revealable) variants.
  • Required team scoping via x-team-id — copy the id from Team Settings → General.
  • Version pinning via Circa-Version.
  • Per-key rate limits at 300 requests / minute.
  • Live request logs (with team id and API-key prefix on every row), usage charts, and a real-time event stream in the authenticated developer portal.
