A2A API Contract

The Agent-to-Agent interface allows external AI agents to programmatically discover and interact with your business services.

Discovery Protocol

External agents can query your A2A endpoint to receive a structured JSON map of your business capabilities, pricing, and availability.

  "trust_score": 0.98,
  "endpoints": {
    "query": "/a2a/v1/query",
    "book": "/a2a/v1/book"
  }
}

Structured Reasoning

Responses are served in JSON Schema format for direct LLM consumption.

Verified Handshakes
