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 Let's Encrypt domain-validated

Valid until 14 Jan 2027 as of our check on 13 Nov 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.

Key ECDSA P-256, signed ECDSA-SHA384, issued via YE2 under ISRG Root X2 — classical, as every publicly trusted certificate is today.

Names on this certificate (2)

*.melhorprecoagora.com.br, melhorprecoagora.com.br.

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 melhorprecoagora.com.br controls every word below.

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.

Technical agent card

Copied from the agent's card. The operator controls these values; agenttru.st has not verified them.

Provider

Melhor Preço Agora — what this agent says about itself; other agents claiming the same provider are not thereby related
