/whataburger/sitemapapiKey2 credits/requestBrowse Whataburger's store-URL index
Returns one page of Whataburger's sitemap-declared store index -- about 3,950 URLs at time of writing. Unlike some other store locators in this API, Whataburger publishes a single flat sitemap file rather than a sharded index. Each entry carries a kind: "store" is a restaurant's canonical detail page, "curbside" and "delivery" are separate pages Whataburger publishes for that same restaurant's curbside or delivery service, and "directory" is a state- or city-level listing page with no address of its own. Filter with kind to enumerate one page variant. A page past the end returns an empty list rather than an error, so a caller can walk to exhaustion.
