Verified by agenttru.st

Everything here is a check agenttru.st performed itself. Assurance, protocol, hosting and freshness are in the card above and are not repeated.

Certificate: Issued by Google Trust Services domain-validated
Valid until 14 Dec 2026. A wildcard certificate: its other hosts are invisible here, because CT logs the wildcard, not them.

Control of the hostname was checked; nothing about who operates it.
DANE / TLSA: Verified — the served certificate matches a DNSSEC-signed TLSA record
Discovery: Well-known document
This host also publishes a DNS-AID SVCB record declaring itself an agent speaking a2a, served with a DNSSEC-validated answer. A declaration is not a verification — the fetch above is what proved it — but it is a deliberate statement by whoever controls the zone.

This host also publishes an ARD catalog (/.well-known/ai-catalog.json) declaring 1 resource. The catalog's entries are the publisher's claims, not something agenttru.st verified.

What this agent says it can do

Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of travel.agentplayground.dev controls every word below.

Flight search

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.

flightsflight-searchtravelquote

Examples it gives

search_flights MAD LHR 2027-03-15
{"action":"search_flights","input":{"origin":"MAD","destination":"LHR","departure_date":"2027-03-15","adults":1}}

Travel checkout

Second step. create_checkout(quote_id, merchant_id, currency) turns one quote from flight-search into a payment intent and stops there — nothing is charged and no ticket is issued. Needs the bearer authorization described in securitySchemes.bearer. As an A2A data part: {"action":"create_checkout","input":{"quote_id":"<id of the chosen option>","merchant_id":"…","currency":"…"}}; as a text part: create_checkout <quote_id>.

travelcheckoutpayment-intent

Examples it gives

create_checkout q_REPLACE_WITH_RETURNED_QUOTE_ID
{"action":"create_checkout","input":{"quote_id":"q_REPLACE_WITH_RETURNED_QUOTE_ID","merchant_id":"agentplayground-travel-seller","currency":"EUR"}}

What its catalog declares

From the ARD catalog this host publishes at /.well-known/ai-catalog.json. The operator controls every entry; agenttru.st verified that the catalog exists and parses, and nothing about what the entries say.
