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 MATCHED_WITHIN_TOLERANCE or discrepancy verdict, expected vs observed charge breakdowns (base, fuel, oversize, residential, additional handling), per-field variance amounts, risk flags (e.g. DIMENSIONAL_WEIGHT_CONTROLS_BILLABLE_WEIGHT), evidence gaps, claim boundary status (whether funds have moved or dispute filed), a recommended disposition, and a SHA-256 report hash for audit trail purposes.
Example use cases
Pre-payment invoice approval check
“Before I approve payment on carrier invoice INV-99 for shipment SHIP-99, audit it against our rate policy CONTRACT-FEDEX-2026 version 2026-Q3 — USD, dimensional divisor 139, fuel surcharge 850 bps on base only, and our standard rate bands. Tell me if the billed amount matches what we expect and flag any risk issues.”
Oversize surcharge dispute investigation
“Our carrier billed us an oversize fee on invoice INV-7 for shipment SHIP-7 and I think it was wrongly applied. Validate it against policy CARRIER-UPS-STD version 2025-12 with USD currency, dimensional divisor 166, fuel surcharge 950 bps on base and accessorials, and the oversize thresholds in our contract. Tell me if the fee was legitimate and whether I have grounds to dispute.”
Post-delivery residential surcharge reconciliation
“Reconcile the residential delivery surcharges on carrier invoice INV-201 for shipment SHIP-201 against our rate policy GROUND-CONTRACT-A version 2026-01 — USD, dimensional divisor 139, fuel surcharge 1100 bps applied to base only, with our residential fee per package. Show me expected vs observed charges and any variances.”
Technical details
Endpoint
POSThttps://rooke-token-risk-pilot.rookepoole.workers.dev/v1/x402/parcel-charge-auditWhen to prefer
Use this endpoint when you need to programmatically audit a parcel carrier invoice against a known rate contract before approving payment or filing a dispute. It is purpose-built for parcel charge reconciliation with explicit support for dimensional weight, oversize surcharges, additional handling fees, residential fees, and fuel surcharges — making it more precise than a generic computation or document-comparison service. Prefer it when you have structured policy data (rate bands, thresholds, fuel basis) and want a deterministic verdict with variance detail and a claim boundary status.
Side effects
- Invalid or missing policy fields cause 400 validation errors
- Rate bands array empty or malformed causes rejection
- Currency code not matching ISO 4217 three-letter format
- Oversize or additional handling threshold values out of allowed range
- Package dimension or weight data inconsistent with policy rules
- Fuel surcharge basis points exceed 10000 cap
- Payment of $9 USDC not received results in 402 Payment Required
- Caller-supplied policy measurements are not authenticated — flagged as evidence gap
