How this service works
RunOnProof Payment Decision decides whether to release a US supplier payment before funds move. 0.79 USDC: scoped checks, reasons, evidence and signed proof binding supplier, invoice digest, amount, payee/destination and mandate. FEDERAL_ONLY. No state checks, bank ownership or invoice authenticity guarantee; never executes payment. HOLD/UNDETERMINED are not permission to pay; HOLD may be paid. Recover the same acquired result without paying again. See the provider guide.
Output
Returns a decision of ALLOW, HOLD, or BLOCK for the supplier payment, along with structured reasons for the decision, remediation steps if the payment is held or blocked, a cryptographically signed Proof Capsule for audit and compliance, and a deterministic replay identifier. Coverage is FEDERAL_ONLY; no state-level checks are performed. The endpoint never executes the actual payment.
Example use cases
Pre-payment vendor fraud check
“We're about to pay a new vendor $120,000 for equipment — can you run a RunOnProof supplier payment decision for supplier entity SUP-00788, invoice INV-9902, buyer org ORG-20011, with low risk tolerance under our federal policy before we move the funds?”
Accounts payable invoice verification
“Our AP team has invoice INV-2024-5530 from supplier SUP-00134 for $32,000 — get a signed RunOnProof release-payment decision for buyer ORG-10099 using our standard risk policy so we have proof on file before we approve the payment.”
Disputed payee account verification
“Before we wire $85,000 to what looks like a new bank account for supplier SUP-00456, run a RunOnProof payment decision check on invoice INV-77231 for buyer ORG-30022 with high risk tolerance flagging — I need to know if this should be held or blocked and why.”
Technical details
Endpoint
POSThttps://api.runonproof.com/v1/us/decision-gates/release-payment-to-supplierWhen to prefer
Choose this endpoint when you need a cryptographically signed, auditable go/no-go decision on a US supplier payment before funds are released — especially in accounts payable workflows requiring fraud prevention, buyer mandate verification, or compliance proof. Prefer it over generic fraud APIs when you need deterministic replay, a Proof Capsule for audit, or structured remediation guidance. Note it is FEDERAL_ONLY and does not execute payments or initiate monitoring.
