ILLUSTRATIVE DECISIONPAYMENT DECISION
THE QUESTIONRelease this supplier payment?
Ⅱ
OUTCOME
HOLD
The payee and destination do not match the evidence supplied.
A real delivery includes signed proof. This example is synthetic.
01 — THE MISSING STEP
A company record is not
a payment decision.
Your workflow has a supplier, an invoice and a destination. Payment Decision connects those inputs with supported evidence and policy, so your system can decide its next step — and retain the reason.
02 — ONE PRODUCT
One operation.
One evidence-backed answer.
Supplier, invoice, payee and mandate checks belong to the Payment Decision. One fee covers the assessment and its signed proof.
Evidence with a boundary
Evaluate supported official sources and the applicable policy. Missing or stale evidence stays visible.
A decision your software can use
Receive a structured outcome, reasons, conditions and next steps, with a signed Proof Capsule.
Built for accounts-payable platforms, procurement software, payment workflows and agent builders.

Check. Decide.
Keep the proof.
Add a decision step before your existing payment execution. Your system retains control of the funds.
Prepare the operation
Use the schema to bind the payment facts and signed buyer inputs. Check eligibility before paying.
Request the decision
Your authorized buyer pays 0.79 USDC through x402 on Base. The service evaluates the scoped evidence.
Apply the result
Read the outcome, conditions and validity. Proceed only when your own authority and policy permit it.
Verify and retain
Verify the Proof Capsule. Recover the same acquired result after a lost response without paying again.
ALLOW · ALLOW_WITH_CONDITIONS · HOLD · BLOCK · UNDETERMINED
A HOLD is a useful result, not payment permission. It can be a successfully delivered paid decision.
04 — PROOF, NOT A PROMISE
An answer you can
inspect later.
The signed Proof Capsule connects the decision to the request, policy and supporting evidence. Your team can inspect what was decided, on which basis, and within what limits.
