Ballerina A2A Library

A Ballerina client library implementing the Agent2Agent (A2A) protocol, letting one AI agent discover another agent's skills and delegate and track work with it.

Ballerina A2A Library

This module provides a Ballerina client for the Agent2Agent (A2A) protocol version 1.0, an open protocol for communication between independent AI agents. An agent publishes an Agent Card describing its skills, transports and authentication requirements; a client built with this library reads that card and talks to the agent over the transport it declares, so an agent can discover what another agent can do, delegate work to it, and follow that work as it progresses.

It implements the client side of the exchange over the HTTP+JSON binding. As part of the Ballerina Library, its own issue tracker and project boards live in the parent Ballerina Library repository rather than in this one, which holds only the module's source.

It is written in Ballerina, built with Gradle, and released under the Apache-2.0 license.
