/subway/sitemapapiKey2 credits/requestBrowse Subway's global store-URL index
Returns one page of Subway's sitemap-declared store index -- 22,700+ URLs across 2 shards at time of writing, covering a country/region/city/street tree worldwide. This is the cheapest way to enumerate Subway locations, and it is the entry point Subway's own robots.txt declares. Each entry carries its URL, the locator path GET /subway/store takes, and a depth: the deepest entries are store pages, shallower ones are country, region and city directory pages listed in the same sitemap. A page past the end returns an empty list rather than an error, so a caller can walk to exhaustion.
