  Agent Bench operates agenthaven.dev, a DNSSEC-signed zone that publishes AI agents through DNS-AID, and runs
  one live agent in it: the Agent Bench Travel Merchant at travel.agenthaven.dev — a proof-of-concept seller
  agent that quotes real flight fares (Google Flights via SerpApi) and turns a chosen quote into a Stripe
  test-mode payment intent under a buyer-supplied spending mandate. It is reachable over A2A (JSON-RPC 0.3,
  agent card at the canonical well-known path, pinned by SHA-256 digest and ES256 signature in the DNS SVCB
  record) and MCP (2025-06-18, two tools with full input and output schemas, anonymous tools/list). It
  publishes a SPIFFE JWT-SVID for the running instance, DANE TLSA pins, an ARD trust catalog, a GoDaddy ANS
  registration and a public hash-chained ledger of every quote, refusal and checkout. No OpenAPI, no SDKs, no
  pricing; no real money moves and no ticket is issued.

  name: Agent Bench Travel Merchant
  description: >-
    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.
