Agent Bench Travel Merchant

Seller agent for flight search and travel checkout, exposed on one host through two protocol doors: A2A JSON-RPC 0.3 at https://travel.agenthaven.dev/a2a (message/send with a DataPart {action, input} or a one-line TextPart) and MCP 2025-06-18 at https://travel.agenthaven.dev/mcp (initialize, ping, tools/list, tools/call). Two operations, called in order: search_flights (anonymous; IATA codes and an ISO date in, up to two signed quotes valid ten minutes out — cheapest and fastest, with itinerary and EUR fare in minor units) and create_checkout (bearer JWT under a spending mandate; turns one quote into a Stripe test-mode payment intent and stops — no ticket, no real money). Every response carries a request id and an evidence block naming the merchant, the card digest and the SPIFFE signer; every call is written to the public hash-chained ledger at /ledger. No OpenAPI: the machine-readable contract is tools/list.
