list_categoriesList the private-label product categories Patent-Gap tracks for expiring design patents.
newly_expirableCross-category feed of design patents that just became (or are about to become) free to make — i.e. fresh off-patent private-label opportunities, soonest-expiry first, already recall- and supplier-screened.
screen_patentScreen ONE US patent by publication number (e.g. USD689332S1): compute its statutory expiry/status, join CPSC recall-safety for its category, and run an OFAC/OIG screen on the assignee. Returns the freedom-to-operate read (design-patent scope; not legal advice).
category_opportunity_reportPAID (x402, $0.03 USDC on Base). Full off-patent opportunity report for a category slug (see list_categories): every newly-expirable design patent with computed expiry, CPSC recall-safety band, and OFAC/OIG supplier screen, ranked by actionability. Free callers get a preview + x402 challenge.
