# Serve a company logo

> The image bytes for a domain, ready to drop into an `<img>` tag. Authenticated with a publishable key in the `token` parameter, so it is safe to put in a browser. A domain we have not seen yet answers with a monogram immediately and the real logo on the next request.

info:
  title: Hydrafetch API
  description: >-
    Hydrafetch is a web data API for LLMs and agents. Send a URL and get back
    clean Markdown, the page's own structured data, schema-shaped JSON, links,
    or a summary, with the navigation, banners and boilerplate stripped out.
    Scrape one page, crawl a whole site, run a search, or extract to a schema,
    all through one API with one response shape. Every call costs one credit a
    page whatever it took to fetch, and failures are never billed.


    Point us at a whole site and get every page. Ask a question and get answers
    with per-field

    confidence and the passage each value came from. You describe the outcome
    you want — the

    pipeline decides how to get it.


    ## Authentication


    Every request is authenticated with your API key in the `X-API-Key` header.
    Keys are scoped to a

    workspace and carry its credit balance.


    ## Credits


    Calls are billed in credits and charged only on success. A standard scrape
    is one credit; richer

    formats and the extraction tier cost more. Each response reports what it
    consumed.


    ## Conventions


    All timestamps are UTC ISO 8601. Long-running jobs (crawl, batch) return a
    job id you poll, or a

    webhook you register. Errors return a structured body with a stable `code`
    and an HTTP status.

tags:
  - name: Scrape
    description: >-
      Turn one URL into clean, LLM-ready content. Ask for Markdown, HTML, links,
      or the page’s own structured data, and poll a job id when a fetch runs
      long.
  - name: Crawl & batch
    description: >-
      Whole sites rather than single pages. Map every URL, crawl with depth and
      path rules, batch a list you already have, and read the webhook deliveries
      for either.
  - name: Search
    description: >-
      Search the web and get the ranked results back already scraped, so an
      agent has content to cite rather than links to fetch.
  - name: Extract
    description: >-
      Pull schema-shaped JSON out of one or many pages, with optional per-field
      confidence and the source passage behind each value.
  - name: Brand
    description: >-
      Resolve a domain into the company ready to render: logos for light and
      dark, the palette ranked by how the site uses it, fonts, socials, and the
      design system behind them.
  - name: Media
    description: >-
      Images and screenshots from a page, with source and alt text, or a
      rendered capture of the page as it appears.
