It is exposed as POST /api/v1/returns-delivery/return-reason-analyze 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: Orders, addresses, events, and rates supplied in the request. Limitations: Records are copied only from labeled fields in the request. No carrier tracking event is added. An address check does not confirm that a carrier can deliver. A return cost and a return window come only from supplied rates and day counts. No carrier account is contacted and no return is initiated. Outputs are compliance prechecks, drafts, or data lookups for human review. They are not official determinations, legal advice, identity confirmation, or certified filings.
