    Why it is in this group

    • The description's first verb is "return": a word for reading.
    Description, as the server wrote it
    ReturnCheck verifies which return policy actually applies to this purchase. 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.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
