The agent's proof of identity was rejected

tragent reports this at the “Reach checkout” stage. The question there is “Can it get through checkout?” Every required field has to be labelled, and no step may need a human gesture only a person can make.

Most agents fail at this point. The few that find a way round it spend more time and model calls doing so, and may give up before checkout.

Accept the signed agent identity headers on checkout endpoints, or verified agents cannot complete a purchase they have already priced.

Run the check that reported AUTH_HEADER_REJECTED again after the change. The scan needs no account; an issue found during an AI shopping test needs that test run again.
