Agentic AI Foundation

Agent2Agent (A2A)

Agent2Agent (A2A) is an open protocol that lets AI agents built by different organisations, on different frameworks, discover each other's capabilities, communicate, delegate tasks and collaborate on multi-step work without sharing internal implementations. Discovery happens through an agent card published at /.well-known/agent-card.json. Hosted by AAIF.
