OpenAgent Compat Lab: Deterministic Compatibility for Agent Endpoints
An OpenAgent Compat Lab is a deterministic testing environment that verifies an agent endpoint actually conforms to a protocol contract — running real JSON-RPC calls, validating the response against a published schema, and checking authentication before an agent is ever trusted to interoperate. It answers the question “can these two agents talk” with evidence rather than a handshake. As platforms like A2Apex score agents on a 0–100 trust scale using live endpoint tests, and as the A2A protocol gathers more than 50 launch partners, deterministic compatibility testing has become the missing trust layer for agent interoperability. ...
