It is exposed as POST /api/v1/ecommerce-fraud/refund-abuse-pattern-detect and priced at $0.04 USDC on Base. Payment uses the x402 exact scheme: an unpaid call returns HTTP 402 with payment requirements; after paying the exact USDC amount, retry the same request with a payment-signature header and Idempotency-Key. No account and no API key are required. Data sources for this product: Order history supplied in the request. Limitations: Patterns are calculated only from the orders in the request. One signal is an indicator, not a finding that a customer is fraudulent. No payment is processed, no order is blocked, and no merchant account is accessed. A full card number is not copied. A statistical outlier is not confirmed fraud. Outputs are compliance prechecks, drafts, or data lookups for human review. They are not official determinations, legal advice, identity confirmation, or certified filings.
