How this service works
Public static preview plus paid token controls, risk consensus, AI security, webhook reliability, developer security, schedule risk, decision analysis, API release compatibility, accounts-payable reconciliation, e-commerce return eligibility, SaaS subscription-proration, sales-commission reconciliation, parcel-charge reconciliation, SLA service-credit reconciliation, advertising spend-and-fee audit, contract-renewal audit, workforce timecard reconciliation, hotel booking-commission reconciliation, and warehouse cycle-count adjustment reconciliation products for autonomous agents.
Output
Returns a structured audit report including a top-level verdict (e.g. MATCHED_WITHIN_TOLERANCE or EXCEPTION), a recommended disposition for the approval workflow, a list of blocking and review exceptions with details, per-line comparisons of invoiced vs. received quantities and prices, potential overpayment exposure in minor currency units, applied tolerance settings, a SHA-256 report hash for audit trail, and evidence gap disclosures (e.g. documents not independently authenticated).
Example use cases
Pre-payment vendor invoice check
“Before we pay this invoice from Acme Supplies — INV-2024-0055, vendor ACM-001, $4,800 USD total, 3 line items each tied to PO-7712 lines — can you run a three-way match against our two goods receipts GR-201 and GR-202 and tell me if there are any discrepancies or if it's safe to approve?”
Detecting overcharged unit prices
“We got an invoice from vendor PARTS-CO, invoice ID INV-5500, claiming $15,000 USD for 500 units at $30 each on PO line PO-L-99, but our receipt GR-310 only shows 480 units received. Run a three-way match with zero tolerance and flag any overpayment exposure.”
Automated AP reconciliation with rounding tolerance
“Audit invoice INV-88321 from vendor SUP-17 — total declared as $9,999.50 USD across 5 lines tied to purchase order lines — against receipts GR-400 through GR-403, and allow up to 50 basis points of quantity overage and $100 rounding tolerance so minor discrepancies don't block payment approval.”
Technical details
Endpoint
POSThttps://rooke-token-risk-pilot.rookepoole.workers.dev/v1/x402/invoice-three-way-match-auditWhen to prefer
Choose this endpoint when you need automated, structured validation that an invoice matches both a purchase order and goods receipts before approving payment — especially in autonomous AP workflows where a machine-readable verdict and disposition recommendation are required. It is well-suited for per-invoice spot checks or automated pipeline integration where configurable tolerances (quantity overage, price overage, rounding) need to be applied consistently. Prefer this over manual review or general-purpose LLM analysis when you need a deterministic, auditable report hash and structured exception list for downstream workflow decisions.
Side effects
- Invoice lines referencing PO line IDs not present in receipts — results in evidence gap or exception
- Declared total does not match sum of line amounts plus tax and shipping — triggers arithmetic exception
- invoicedQuantity exceeds receivedQuantity beyond tolerance — blocking exception flagged
- Unit price overage beyond configured basis points — exception raised
- Malformed currency code or missing required fields — validation error returned
- Receipt array empty or missing lines for referenced PO lines — evidence gap flagged
