CDQ Genius - A2A (JSON-RPC 2.0) API (1.0)

This document describes CDQ Genius's Agent2Agent (A2A) protocol JSON-RPC 2.0 binding, per the A2A 1.0 specification, §9.

How the transport works

The A2A JSON-RPC binding exposes one physical HTTP endpoint. Every operation is a POST of a JSON-RPC 2.0 envelope to the base URL, and the server dispatches on the envelope's method field:

POST https://api.cdq.com/a2a/cdq-genius/
Content-Type: application/json
A2A-Version: 1.0
X-API-KEY: {YOUR_API_KEY}

Supported methods are shown as selectable request examples on the POST / operation below (SendMessage, GetTask, CancelTask).

The Agent Card (served by the GET operation below) is the authoritative source for the endpoint URL, transport, and capabilities.
