Tools: inspect_payment get_receipt verify_receipt create_payment_receipt
inspect_payment | Use this when the user wants to check a proposed payment against explicit rules before sending it, for example whether the amount, recipient, asset or network matches their policy or would exceed their limit. Compares the proposal with the user's structured policy and returns ALLOW, REQUIRE_APPROVAL or BLOCK. It does not send, sign or authorize payments, perform sanctions screening, or certify saf params: action*, policy* |
get_receipt | Use this when the user has an exact public OCD receipt ID (OCD-RCP-...) and wants to see the recorded evidence, for example what a payment receipt contains. Requires the exact receipt_id; it cannot search or list receipts, and has no payment, publication or private-operation access. Returns the unchanged signed envelope or a bounded not-found reason; private and unknown IDs are indistinguishable. params: receipt_id* |
verify_receipt | Use this when the user wants to know whether an OCD receipt proof is valid, for example whether a receipt is authentic or its evidence signature checks out. Returns VALID, INVALID or UNVERIFIABLE for one public receipt_id OR an envelope the user may share with OCD, without credentials or payment authorizations. Envelopes are not published or echoed. VALID means the signed receipt verifies under OC params: receipt_id, envelope |
create_payment_receipt | Use after a supported payment has occurred to independently observe its exact network and transaction reference and create or return a signed OCD receipt. Never sends, signs or authorizes payment. Policy remains UNKNOWN: no agent identity, wallet ownership, provider identity or service-delivery claim. Pending requests must be retried with the same reference, not another payment. params: network*, transaction_reference* |
