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 JSON object with: a verdict string (e.g. MATCHED_WITHIN_TOLERANCE), a reconciliation object showing expected vs observed media spend, fee totals, and variance in minor currency units, a list of risk flags (e.g. PROJECTED_MEDIA_BUDGET_OVERRUN), pacing data (elapsed/total days, projected spend), a list of unknown observed fee lines, expected fee lines with computed amounts, a recommended disposition, evidence gaps, a claim boundary object indicating no funds were moved or invoices approved, and a SHA-256 report hash for audit trail purposes.
Example use cases
Monthly agency fee overbilling check
“My agency just sent invoice INV-2024-09 for our September campaign under agreement AGR-BRAND-001 v2 (USD, Sep 1–30, $50,000 media budget). The invoice shows $48,200 media spend, a $7,230 management fee listed as 1,500 bps of media spend, and a $200 credit, totaling $55,230. Check if the fee is correctly calculated and tell me if we're being overbilled.”
Campaign budget overrun risk alert
“We're 3 days into a 10-day campaign (agreement CAMP-Q3-PILOT, USD, Jul 1–10, $100,000 budget). Invoice INV-PRELIM shows $42,000 spend so far. Our contract has a 12% management fee on media spend with a $5,000 minimum. Flag whether we're on pace to exceed the budget and what the projected overrun looks like.”
Unknown fee line investigation
“Our media partner sent invoice INV-AUDIT-77 under agreement MED-2025-Q4 (USD, Oct 1–Dec 31, $200,000 budget). Besides the expected 1,000 bps platform fee, there are two extra line items I don't recognize — 'tech surcharge' for $1,500 and 'data activation fee' for $800. Run an audit and tell me which fees are not covered by the signed agreement.”
Technical details
Endpoint
POSThttps://rooke-token-risk-pilot.rookepoole.workers.dev/v1/x402/ad-spend-fee-auditWhen to prefer
Choose this endpoint when you need a structured, auditable verdict on whether an advertising invoice's fees, credits, and totals match a signed media agreement — especially when the agreement has complex fee rules (percent-of-spend with floors/ceilings, fixed fees). Prefer it over manual spreadsheet checks or generic reconciliation APIs when you need risk flags, budget pacing projections, and a tamper-evident report hash in a single call. It is purpose-built for ad-spend and agency-fee reconciliation, not general AP matching.
Side effects
- Missing required invoice or agreement fields returns a 400 validation error
- Fee rule calculationMode enum mismatch causes rule to be skipped or flagged as unknown
- Period dates in wrong format (not YYYY-MM-DD) cause parsing errors
- observedTotalMinor inconsistent with observed line items may produce a non-zero variance unexpectedly
- Payment failure (x402) if USDC balance is insufficient — call is not executed
- Agreement version mismatch between caller-supplied data and actual signed contract yields CALLER_SUPPLIED_AGREEMENT_CAMPAIGN_AND_INVOICE_FACTS_NOT_AUTHENTICATED evidence gap
