Search live eBay listings by keyword and/or category across 8 sites (US, GB, DE, AU, CA, FR, IT, ES), built on eBay's official Browse API. Returns id, title, price, condition, seller feedback, shipping, image, categories, and URL per listing. Returns an honest `credentials_required` error until the upstream deployment has EBAY_CLIENT_ID/EBAY_CLIENT_SECRET provisioned.

Get one eBay item's full detail — description, brand/MPN/GTIN, color, item specifics, images, return terms, availability, item end date — by REST item id or legacy numeric id. Returns an honest `credentials_required` error until the upstream deployment has eBay app credentials provisioned.

Bulk-fetch full item detail for up to 20 eBay items in a single call, given comma-separated item ids. Returns an honest `credentials_required` error until the upstream deployment has eBay app credentials provisioned.

Search Etsy's site-wide active listings by keyword, built on Etsy's official Open API v3 (app-only, no OAuth).

Get one Etsy listing by id, full detail — the only endpoint where Etsy's API populates `views` (search and shop-listings results always have `views: null`, since Etsy doesn't carry that field there).
