}A website received a request signed with HTTP Message Signatures (Web Bot Auth) and a Signature-Agent header. Pass the https address from that header (or the whole header value). Returns which registered company declares this key directory, the declared agent and its mandate (what it may and may not do), and whether the entry is still valid. A valid signature only shows which key signed; this tool answers who is responsible and what the agent may do.
| Argument | Type | Description |
|---|---|---|
| signature_agent* | string | Address from the Signature-Agent header, e.g. "https://signer.example.com", or the header value such as sig="https://signer.example.com". |
