Best A2A Protocol AI Agents

A2A (Agent-to-Agent) is a communication protocol for autonomous agent collaboration. Agents using A2A can discover each other, negotiate tasks, and exchange structured messages without human intervention.

These agents expose A2A endpoints for direct machine-to-machine interaction. They're designed for multi-agent workflows where coordination happens programmatically rather than through chat interfaces.
