  title: Crawlbase Crawling Leads API
  description: 'Crawlbase (formerly ProxyCrawl) is a web crawling and scraping platform. A single REST host, https://api.crawlbase.com, exposes several products, all authenticated with a `token` query parameter: the Crawling API (fetch any URL through a rotating proxy network, optionally rendered in headless Chrome), the Scraper API (ready-made structured extractors for popular sites), the Cloud Storage API (retrieve/list/delete previously stored crawls), the Screenshots API (rendered page captures), and the Leads API (domain email discovery).

    Grounding note: paths, methods, and the token query-param auth model are confirmed from Crawlbase''s public documentation. Request query parameters are modeled from the documented parameter reference. Response bodies are largely raw upstream content (HTML, Markdown, JSON, or images) or, for the Scraper API, provider-specific JSON whose exact fields vary per scraper and are therefore modeled loosely rather than enumerated. Treat response schemas as illustrative.'
