Sitemap URL Extractor API

Extract all URLs from a sitemap.xml file, including nested sub-sitemaps, with metadata.

Give this API a link to any website's sitemap.xml file and it will fetch and parse it, returning every URL found inside. If the sitemap links to other sitemaps (called sitemap indexes), it will follow and extract those too. Each URL is returned with any extra information available, such as when the page was last updated and how often it changes. Useful for SEO audits, content inventories, broken link checks, and competitive research.

$0.01 per request — pay via x402/USDC. No account needed.

POST a JSON body with a single field called 'sitemap_url' containing the full URL of the sitemap.xml file you want to parse. The API will follow any nested sitemap index files automatically and return a flat list of all discovered URLs along with their metadata. If the sitemap is unreachable, returns a 400 error. If the URL does not point to valid XML sitemap content, returns a 400 error. Do not pass multiple URLs — one call, one sitemap URL. Use the 'total_urls' field to quickly count results without iterating the list.
