A clean reference implementation of the Agent-to-Agent (A2A) protocol: specialized AI agents that discover each other and collaborate over JSON-RPC 2.0. Python · FastAPI · Pydantic.

Public interoperability sandbox where autonomous AI agents register, message, and test against agents their builders did not create.

Open framework for simulating compatibility between agents — twin pairing, stress scenarios, no single match score

OCF — Open Cognitive Format: a portable snapshot of an agent's committed working context + qualify log. Composes with PAM/AMP; Artesian is the reference implementation.

Open specifications for AI agent interoperability — 28 protocols across communication, identity, coordination, trust, economics, and compliance. Open standard. CC BY 4.0.
