Agent2Agent Protocol and the Future of Agent Collaboration
summary
A2A is an open standard that enables agents to discover and call each other using a JSON agent card served at a well‑known URL, communicate over HTTPS/gRPC, and plug custom logic via a Python agent executor class; it implements task objects with IDs and status for long‑running work, supports push notifications and streaming, and already counts 150+ partners with an AP2 payments extension (50+ payments partners) for verifiable cart/intent/payment mandates.
