  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.
