  title: Crawlbase 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.

        Fetches the target `url` through Crawlbase's proxy network and returns
        the page. Use the Normal (TCP) token for static HTML/JSON, or the
        JavaScript token to render the page in headless Chrome before returning
        it. Crawlbase status is surfaced in the `pc_status` response header;
        requests that do not return `pc_status: 200` are not charged.
