A2Apex

A2Apex is a testing and certification platform for the A2A protocol. It validates your agent’s card, live endpoints, state transitions, streaming, and security, and reports a clear compliance score. Run live tests, debug via chat, and ensure JSON-RPC and SSE behavior match the spec. Earn certification badges that link to a public registry listing, and access results via API. Plans range from free to enterprise with unlimited testing, analytics, retesting, and CI/CD integration to help your agents earn trust.
