# Extract URLs from a sitemap.xml

POST https://api.smallest.ai/atoms/v1/knowledgebase/get-sitemap-urls
Content-Type: application/json

Fetches a website's `sitemap.xml`, parses it, and returns the list of URLs inside. Use this before calling `POST /knowledgebase/{id}/scrape-urls` to let the customer pick which URLs they actually want indexed.

Returns `422` if the URL doesn't return a fetchable sitemap or if the XML is malformed.

Reference: https://docs.smallest.ai/api-reference/voice-agents/knowledge-base/extract-sitemap-urls
