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 8 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.
DANE / TLSA: Not verified (TLSA query returned RCodeNameError)
Discovery: Well-known document
AI use policy: Search: yesAI training: nouse: reference

What this site's robots.txt says about how AI may use its content. Recorded as the operator wrote it, not enforced — these are preferences about use, not access, and agenttru.st only reads the agent's own discovery documents.

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 proofjson.org controls every word below.

Assess invoice before payment

Assess invoice payment risk using supplied invoice data, supplied context and configured policy. Returns allow, review or block with reasons, evidence, checks performed and checks not performed. External supplier, IBAN, sanctions and payment-history checks require configured external trust adapters.
