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 Amazon domain-validated
Valid until 31 Mar 2027.

Control of the hostname was checked; nothing about who operates it.
DANE / TLSA: Not verified (TLSA RRset not DNSSEC-validated (no AD bit))
Discovery: Well-known document
This host also publishes a DNS-AID SVCB record declaring itself an agent speaking a2a. 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 buyer.agentsanctuary.dev controls every word below.

Purchase planning

Create a deterministic, read-only purchase plan. Invoke with a data part such as {"action":"purchase-planning","goal":"Compare flights to Lisbon"}; no seller or payment call is made.

Seller inspection

Fetch and return a bounded public JSON capability document from an explicitly allowlisted HTTPS seller. Invoke with {"action":"seller-inspection","seller":"travel.agentplayground.dev"}. No credentials are forwarded.

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.
