For agents

Use when

Use this when an agent is about to pay a seller it has not dealt with and wants plain signals first: domain age from RDAP, whether HTTPS works, DNS and email authentication, whether a payTo address is well formed, and whether the site publishes terms and a refund policy. Signals only: not a guarantee, not legal or financial advice.

Where the answer comes from

Source and scope

RDAP (IANA bootstrap and the responsible registry), public DNS, and the site's own home page, all read at the time of the call. Certificate issuer and expiry are not available on the runtime and are not reported.

PageVerified reports what it read, with the source it read it from. It is general information, not advice, and not a legal record.
