# Parcel Charge Audit > Parcel Charge Audit is a paid API for AI agents from rooke-token-risk-pilot.rookepoole.workers.dev, paid per call via x402, $9/call, status unknown (last checked 2026-09-14). Validates carrier parcel invoice charges against a caller-supplied rate policy, identifying billing discrepancies, oversize/additional-handling errors, fuel surcharge miscalculations, and dimensional-weight issues across shipment packages. ## Facts - Endpoint: POST https://rooke-token-risk-pilot.rookepoole.workers.dev/v1/x402/parcel-charge-audit - Price: $9/call - Payment: x402 - Status: unknown - Last checked: 2026-09-14 - Activations on Zero: 0 - Tags: x402 - Canonical page: https://www.zero.xyz/c/parcel-charge-audit-abd34064 - Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_5EG1Bi6qPdQW0976dbhHD Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently. ## How to call it through Zero Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`): ```sh zero fetch --capability parcel-charge-audit-abd34064 -d '' ``` Example prompt: Audit this carrier invoice INV-42 for shipment SHIP-42 against our contract policy CARRIER-CONTRACT-42 (version 2026-07): USD currency, dimensional divisor 139, fuel surcharge 1000 bps applied to base and accessorials, with residential fee and the rate bands I'll provide — tell me if the charges match, flag any oversize or dimensional-weight issues, and give me a recommended disposition. ## When to prefer this 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. ## Known failure modes - 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 $9 USDC not received results in 402 Payment Required - Caller-supplied policy measurements are not authenticated — flagged as evidence gap ## How this service works Public static preview plus paid token controls, risk consensus, AI security, webhook reliability, developer security, schedule risk, decision analysis, API release compatibility, accounts-payable reconciliation, e-commerce return eligibility, SaaS subscription-proration, sales-commission reconciliation, parcel-charge reconciliation, SLA service-credit reconciliation, advertising spend-and-fee audit, contract-renewal audit, workforce timecard reconciliation, hotel booking-commission reconciliation, and warehouse cycle-count adjustment reconciliation products for autonomous agents. ## Output Returns a structured audit report including: a MATCHED_WITHIN_TOLERANCE or discrepancy verdict, expected vs observed charge breakdowns (base, fuel, oversize, residential, additional handling), per-field variance amounts, risk flags (e.g. DIMENSIONAL_WEIGHT_CONTROLS_BILLABLE_WEIGHT), evidence gaps, claim boundary status (whether funds have moved or dispute filed), a recommended disposition, and a SHA-256 report hash for audit trail purposes. ## Request schema (JSON Schema) ```json { "type": "object", "properties": { "policy": { "type": "object", "required": [ "policyId", "policyVersion", "currency", "dimensionalDivisorCubicInchesPerPound", "rateBands", "additionalHandling", "oversize", "suppressAdditionalHandlingWhenOversize", "residentialFeePerPackageMinor", "fuelSurchargeBps", "fuelBasis" ], "properties": { "currency": { "type": "string", "pattern": "^[A-Z]{3}$" }, "oversize": { "type": "object", "required": [ "enabled", "feeMinor", "longestSideOverInches", "secondLongestSideOverInches", "lengthPlusGirthOverInches", "actualWeightOverPounds", "minimumBillableWeightPounds" ], "properties": { "enabled": { "type": "boolean" }, "feeMinor": { "type": "integer", "maximum": 9007199254740991, "minimum": 0 }, "longestSideOverInches": { "anyOf": [ { "type": "integer", "maximum": 50000, "exclusiveMinimum": 0 }, { "type": "null" } ] }, "actualWeightOverPounds": { "anyOf": [ { "type": "integer", "maximum": 50000, "exclusiveMinimum": 0 }, { "type": "null" } ] }, "lengthPlusGirthOverInches": { "anyOf": [ { "type": "integer", "maximum": 50000, "exclusiveMinimum": 0 }, { "type": "null" } ] }, "minimumBillableWeightPounds": { "type": "integer", "maximum": 50000, "exclusiveMinimum": 0 }, "secondLongestSideOverInches": { "anyOf": [ { "type": "integer", "maximum": 50000, "exclusiveMinimum": 0 }, { "type": "null" } ] } }, "additionalProperties": false }, "policyId": { "type": "string", "maxLength": 120, "minLength": 1 }, "fuelBasis": { "enum": [ "BASE_ONLY", "BASE_AND_ACCESSORIALS" ], "type": "string" }, "rateBands": { "type": "array", "items": { "type": "object", "required": [ "upToBillableWeightPounds", "baseChargeMinor" ], "properties": { "baseChargeMinor": { "type": "integer", "maximum": 9007199254740991, … (truncated) ``` ## Response schema (JSON Schema) ```json { "type": "json", "example": { "policy": { "currency": "USD", "policyId": "CARRIER-CONTRACT-42", "fuelBasis": "BASE_AND_ACCESSORIALS", "policyVersion": "2026-07", "fuelSurchargeBps": 1000, "dimensionalDivisorCubicInchesPerPound": 139 }, "summary": { "packageCount": 1, "toleranceMinor": 0, "oversizePackageCount": 0, "residentialPackageCount": 1, "dimensionalWeightPackageCount": 1, "additionalHandlingPackageCount": 0 }, "verdict": "MATCHED_WITHIN_TOLERANCE", "expected": { "fuelMinor": 360, "totalMinor": 3960, "oversizeMinor": 0, "baseChargeMinor": 3000, "residentialMinor": 600, "additionalHandlingMinor": 0 }, "observed": { "fuelMinor": 360, "totalMinor": 3960, "oversizeMinor": 0, "baseChargeMinor": 3000, "residentialMinor": 600, "additionalHandlingMinor": 0 }, "invoiceId": "INV-42", "riskFlags": [ "DIMENSIONAL_WEIGHT_CONTROLS_BILLABLE_WEIGHT" ], "variances": { "fuelMinor": 0, "totalMinor": 0, "oversizeMinor": 0, "baseChargeMinor": 0, "residentialMinor": 0, "additionalHandlingMinor": 0, "observedArithmeticMinor": 0 }, "reportHash": "sha256-hex", "shipmentId": "SHIP-42", "evidenceGaps": [ "CALLER_SUPPLIED_POLICY_MEASUREMENTS_AND_INVOICE_FACTS_NOT_AUTHENTICATED" ], "claimBoundary": { "fundsMoved": false, "disputeFiled": false, "invoiceApproved": false, "paymentAttempted": false, "carrierOrRateApiCalled": false }, "schemaVersion": "PARCEL_CHARGE_AUDIT_V1", "packageResults": [], "requestCommitment": "sha256-hex", "recommendedDisposition": "MATCHED_NO_ACTION" } } ``` ## More -
