GET/wayfair/categoriesapiKey1 credit/request
Returns a page of Wayfair categories discovered from Wayfair's own published sitemap, closing the discovery gap where a category id otherwise has to be found elsewhere. Pair a returned id with GET /wayfair/category to browse that category's product grid. name is derived from the category's own URL slug (title-cased), not an authoritative site-provided label. q, if set, case-insensitively filters to categories whose derived name or department contains it.
Optional: q, page, page_size.
Sampled 14 Oct 2026: 40 items. Filled in every item: id, name, department, url. In the sample: name: “Kids Shower Curtains” and 39 other values; url: wayfair.com; department: “baby-kids” and 13 other values.
