Why an AP2 payment was denied. Every variant is a hard stop — the payment is not authorized.

Variants

IntentCartMismatch

The Cart’s intent_id does not match the Intent presented.

MissingSignature

A mandate carried an empty signature.

UnknownKey

A mandate was signed by a key_id not in the trusted keyring.

InvalidSignature

A signature failed Ed25519 verification (tampered / wrong key).

Unpriceable

The cart total is in a currency that can’t be priced against the cents budget (non-USD).

IntentScopeMismatch

The cart’s merchant/category/amount falls outside the Intent’s scope.

CartOverCeiling

The cart total would breach the per-task budget ceiling.
