For the live demo on the landing page, the same endpoints are used with client-side rate limiting (2 calls per week per device).

Authentication

  • Live demo: No authentication required. Rate-limited to 2 calls per week per device fingerprint.
  • Production (via CROO CAP): Authentication and payment settlement are handled by the CROO CAP protocol. No API key needed directly — CROO manages agent identity and USDC escrow.

Content type

All requests and responses use application/json.

Rate Limits & Pricing

Demo rate limits, production pricing, and how CROO CAP payment settlement works.

GET /api/agent/{job_id}
