Developers

Build on EurekaNav's structured AI tools data. REST API, A2A protocol, and machine-readable endpoints for agents and integrations.

A2A Protocol (Agent-to-Agent)

EurekaNav implements Google's A2A protocol for agent interoperability. Any AI agent that supports A2A can discover EurekaNav's capabilities and query tool data via JSON-RPC.
