Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

Capabilities

Tools 4

analisar_url

Use to fetch one public HTTP or HTTPS page and return a source-bounded report with summary, facts, risks and recommended actions. The optional objective controls focus but is never evidence. It does not consult other sources; use verificar_condicoes for condition-by-condition decisions. PT: Analisa uma página pública sem usar fontes externas.

Discovered
consultar_ia

Use for general questions that do not require live web retrieval. Returns a concise model answer and does not fetch URLs or verify current facts. Use analisar_url for a source-bounded page report and verificar_condicoes for evidence-backed decisions. PT: Use para perguntas gerais sem pesquisa web em tempo real.

Discovered
preview_verification

Use this free static preview before paying for verificar_condicoes. Choose offer_terms to inspect warranty, returns and availability; seller_trust to inspect seller identity and authorization; or policy_compliance to inspect required policy terms. It performs no web request, OpenAI call or payment and returns a realistic structured example plus the exact paid next step. PT: Pré-visualização gratuita e estática da verificação.

Discovered
verificar_condicoes

Use before an agent trusts, buys or acts to test 1 to 10 explicit conditions against one public HTTP or HTTPS page. Best fits offer and warranty checks, seller identity or authorization checks, and policy compliance checks. Returns confirmed, rejected or uncertain for every condition with textual evidence when available, plus source, verifiedAt, verificationId and pageHash. Missing evidence produces uncertain, not a false confirmation. Use preview_verification first when the buyer needs a free example. PT: Verifica condições com prova auditável.
