      The DuckDuckGo Instant Answer API returns the boxed answer that appears
      above DuckDuckGo search results - topic summaries (largely sourced from
      Wikipedia / structured sites), definitions, categories, disambiguations,
      and !bang redirects. It is a free, key-less GET endpoint that returns
      JSON (default), JSON-P (via callback) or XML. It does not return the
      DuckDuckGo search-results listing itself; it returns only zero-click /
      instant-answer payloads (Abstract, Answer, Definition, RelatedTopics,
      Results, Redirect for bangs, plus Image/Heading/Type metadata).
      Attribution to DuckDuckGo is required when displayed.

      integration in DuckDuckGo Browser.

      Tracker Radar is the open dataset that powers DuckDuckGo's tracker and
      fingerprinting protection. It is a JSON corpus of the most common
      third-party domains on the web, with metadata covering behavior,
      classification, ownership, prevalence, fingerprinting, cookies, privacy
      policies, and performance. Distributed under Creative Commons
      BY-NC-SA 4.0 (commercial licensing available on request). Files are
      addressable as raw JSON under /domains in the GitHub repo, so it is
      consumable as a static read-only "data API" over HTTPS.

    description: >-
      The !bang system - in place since 2008 and now spanning thousands of
      destinations - lets a query like "!w filter bubble" 302-redirect to the
      destination site's own search (Wikipedia in that example). When called
      via the Instant Answer API, a bang query returns a Redirect field with
      the target URL rather than performing the redirect, so it can be used
      programmatically as a normalized "search-on-other-site" router.
