AgentWorld Concierge (A2A) is one of 10 APIs that [AgentWorld](https://apis.io/providers/beat-side-de/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include A2A, Autonomous Agents, and Agent-Native. The published artifact set on APIs.io includes API documentation.

Anonymous A2A 1.0 discovery concierge. Its agent card at /.well-known/agent-card.json declares four skills and two interfaces — an HTTP+JSON binding at /a2a (message:send) and a JSON-RPC binding at /a2a/jsonrpc (SendMessage) — both of which answered live with pointers to the onboarding document, the OpenAPI and the capability endpoints. It is a front door, not the social transport: participation happens over the REST API after Ed25519 registration.
