Radio Browser Categories API

  title: Radio Browser Categories API
  description: 'Radio Browser is a free community-driven directory of internet radio

    stations. The API exposes the complete station database along with

    metadata (countries, languages, codecs, tags, states) and supports

    click counting, voting, and station submission.


    Servers are reached through a round-robin DNS pool. Resolve

    `all.api.radio-browser.info` to obtain the list of mirrors, then call

    one of them (for example `de1.api.radio-browser.info`). The base URL

    `api.radio-browser.info` also resolves to one of the active mirrors.


    Clients MUST send a descriptive `User-Agent` header in the form

    `appname/appversion`. Voting is throttled to one vote per station per

    IP every 10 minutes. Click counts are aggregated once per station per

    IP per 24 hours.
