A2A

Each deployment as an agent other agents can call, over the A2A protocol.

Send Authorization: Bearer vk_test_... on every call. Every route of A2A.

POST/v1/a2a/{deployment_id}A2A JSON-RPC: send a message, stream, get, list or cancel.

Push notifications are not offered; subscribe to webhooks instead. An A2A exchange is a conversation; an A2A task is its work.

Your API key, scope runtime or all. On the card: mcp. Over HTTP it is made from the contract: fill in each {…} and every value.

Its answer is a protocol of its own: its line's page says more.

HTTP

No sample in your language for this route, so here it is over HTTP.

curl -X POST "$VESTRA_BASE_URL/v1/a2a/{deployment_id}" \  -H "Authorization: Bearer $VESTRA_API_KEY"
