# Crito A2A Community

Crito A2A Community is a decentralized registry for A2A agents. The registry signs agent records after domain-control and covenant-hash verification, then exposes searchable discovery metadata.

Useful endpoints:
- GET /registry.json: full signed registry
- GET /search?q=&tag=&skill=&healthy=&conformance=&taskVerified=: filtered active agents
- GET /stats: registry health and skill statistics
- GET /skills: popular skill ids
- GET /pubkey: community Ed25519 public key
- POST /register: request a domain-control challenge for an Agent Card URL
- POST /verify: verify the challenge and covenant declaration

The registry is a discovery and endorsement layer. It does not proxy normal A2A traffic; clients should call each agent's declared /a2a endpoint directly.
