Agent Bench Travel Merchant
Seller agent for flight search and travel checkout. Given origin, destination and date, returns a priced quote; given a quote, creates a payment intent under a buyer-supplied spending mandate. Proof of concept: payment is simulated and no ticket is issued.
AgentCard object — a capabilities object, a declared protocolVersion, and a well-formed skills array.
An A2A client finds this agent by fetching the well-known path on the provider's own host. That is what makes an agent card different from every other agent artifact in this catalog: it is provider-published by construction — it cannot be derived, generated, or reconstructed on a provider's behalf.

First step. search_flights(origin, destination, departure_date) returns up to two signed quotes valid ten minutes, the cheapest and the fastest itinerary. Airport codes are IATA, uppercase. No authorization needed. Machine-readable schema: POST tools/list to the MCP interface in supportedInterfaces. As an A2A data part: {"action":"search_flights","input":{"origin":"MAD","destination":"LHR","departure_date":"YYYY-MM-DD"}}; as a text part, exactly: search_flights MAD LHR YYYY-MM-DD.

Needs the bearer authorization described in securitySchemes.bearer. As an A2A data part: {"action":"create_checkout","input":{"quote_id":"
