AI provider changes, ready for your agent

Poll one read-only endpoint for source-linked model, API, pricing, lifecycle, research, benchmark, app, and outage events. Every event carries its evidence state, observation time, and original source.

The evidence fields travel with the event

The event object keeps confirmation and evidence separate. `confirmed` says the change passed Radar’s customer-event gate; `evidenceState` records how the source supports it. Corrections and retractions remain explicit fields instead of silently rewriting history.

Cursor polling prevents timestamp gaps

Start with `limit=50`, persist `nextCursor`, and request the next page immediately while `hasMore` is true. Results arrive oldest-first while polling. The older `after` timestamp filter remains deprecated because events sharing a timestamp can be skipped.

Keys are named, one-time visible, and revocable

Radar stores a hash, shows the secret only when the key is created, tracks last use, and rejects revoked keys. A key also stops working when the account no longer has active Pro access.

Agent discovery is already published

The public manifest names the bearer-key environment variable, polling interval, cursor rules, and OpenAPI location.
