  description: 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.

    prompts or train on them. There is no public REST API; access is via the web UI and the in-browser integration in DuckDuckGo
    Browser.

  description: 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.
