How this service works
An independent third-party agent that tells your agent whether to pay an Irish supplier invoice: EXECUTE, REJECT or FLAG. CRO, VIES, IBAN, 3-way match and signature checks. From $0.005 per call in USDC on Base (x402). No account.
Output
Returns a JSON object with: the check type (THREE_WAY_MATCH), outcome (PASSED, FAILED, or FLAG), a reason_code explaining the decision, and a checked_at ISO 8601 timestamp. The calling agent uses the outcome to decide whether to EXECUTE, REJECT, or FLAG the payment for human review.
Example use cases
Automated invoice approval in AP workflow
“We just received an invoice from our Irish supplier Clancy Logistics (CRO IE987654) for €8,750 against PO-2025-0042 and goods receipt GR-2025-0019 — do a three-way match and tell me if we should pay it, hold it, or reject it.”
Catching quantity mismatch before payment
“Our goods receipt for order PO-2024-1122 only shows 80 units delivered but the invoice from Brennan Supplies (CRO IE445566) is billing us for 100 units — run the three-way match and flag whether this should be rejected.”
End-of-month batch invoice review
“Before we close the books, check this invoice from O'Brien Components Ltd (CRO IE778899) against purchase order PO-2025-0310 and goods receipt GR-2025-0297 and give me the match outcome so finance can approve or block the payment.”
Technical details
Endpoint
POSThttps://supplier-payment-verifier-production.up.railway.app/v1/checks/three-way-match?utm_source=zero.xyzWhen to prefer
Use this endpoint when your agent needs to automate accounts payable decisions for Irish suppliers and requires a structured EXECUTE/REJECT/FLAG verdict combining invoice, purchase order, and goods receipt data. Prefer this over manual review or simpler IBAN/VAT checks alone when you need full three-way procurement matching with CRO and VIES compliance validation in a single call. Ideal for agentic finance workflows where human-in-the-loop approval is too slow but unverified payments are too risky.
Side effects
- Missing or malformed invoice/PO/goods receipt objects returns a 422 validation error
- Supplier CRO number not found in Irish CRO registry causes a REJECT outcome
- Amount or quantity mismatch between invoice and PO/goods receipt results in FAILED outcome with reason code
- x402 payment not included or insufficient USDC balance causes a 402 Payment Required response
- Upstream CRO or VIES service unavailable may cause a timeout or 503 error
