Agent Stamp

See who placed the order.

A person, a named agent, or unknown. The line sits on the WooCommerce order you already open.

Order	What arrived	Buyer
#13	Phone browser	Human
#14	ChatGPT-User, no signature	ChatGPT (declared)
#15	curl	Unknown
#20	Valid Web Bot Auth signature	Signed agent

These four rows are from a live WooCommerce checkout. The same column names Claude, Perplexity, Google Agent, Meta, Amazonbot, Mistral, and the other published agents when they are the ones who checked out. A name in the user-agent is not proof. If the signature fails, the order stays Unknown.

What you get

A Buyer column on the orders list, and a box on the order.
Signed when the agent’s key checks out on your server.
Declared when the user-agent is a published agent and nothing was signed.
A Monday email only when an order was not a person.

Checkout is never blocked. Copilot and Grok usually look like a normal browser, so they stay Human until they sign.
