# A2A V0 Accept Task

`POST /a2a/v0/tasks`

Accept a federated task delegated from a peer orchestrator.

Wire format::

    {
      "sender": { ...AgentCard... },
      "task":   { "id": "...", "message": "...", "role": "..." }
    }

Returns 202 with the local federated-task id and the remote task id
that was offered. Validation errors return HTTP 409 so that the
caller's retry policy treats them as terminal (the peer is reachable
and authoritative, no point retrying with the same body).

## Response `202`

Successful Response

- object

## Other responses

- `400` — Invalid sender Agent Card or task body
- `409` — Task rejected (validation, capacity, etc.)
