🟡check_return(product_url, buyer_country, item_condition, reason, purchase_date, ...)
Answer one question: can this specific product actually be returned? BEST RESULTS: send the product page you already have as page_text (or page_html) along with product_url — your browser renders JavaScript and is not blocked by retailers, so this works on any store and is faster. Without it we fetch the page ourselves and reach the policy for about 1 in 3 US retailers (17 of 50 measured 2026-08-28; mostly Shopify and direct-to-consumer brands — large retailers and marketplaces block server-side reads). You get a verified verdict — YES / YES_WITH_CONDITIONS / NO / UNKNOWN — with the exact policy clause quoted verbatim, source URL, return window/deadline, fees and a confidence score. Never invents: returns UNKNOWN instead of guessing, and UNKNOWN is free.

"description": "OPTIONAL. x402 payment authorization, base64 — the same envelope the PAYMENT-SIGNATURE header carries over HTTP. Use it to pay per call with no account and no signup. How: call once without it; if the free trial is exhausted you get the payment terms in structuredContent (x402Version, accepts[]); sign that authorization and call again with payment_signature set. Terms are also published at /.well-known/x402. UNKNOWN verdicts are never settled: the authorization simply expires unused."
