How to Add an NZB Indexer (Newznab API) to Your Downloader

An indexer is a website that keeps a searchable catalogue of what has been posted to Usenet, and gives you an NZB file for each item. Most indexers use the same standard API, called Newznab, so any good downloader can talk to them.

What you need from your indexer

  • The API URL, usually the site address, for example https://indexer.example/api.
  • Your API key, a long string of letters and numbers found on your profile or API page. Keep it private: it’s like a password.
  • RSS feed URLs (optional), if you want new items to appear automatically.

Adding an indexer to NZB Grab

  1. Open NZB Grab, click the cog for Settings, then choose Feeds.
  2. Under Add a source, pick your indexer (or Other Manual API), give the tab a name, and paste in the API URL and your API key.
  3. Click Add tab. The indexer appears as its own tab.
  4. Open Feeds & Search, browse the tab or type in Search titles, then tap USE on any result to start downloading.

Adding your own indexers, RSS feeds and in-app search are licensed features. The free app opens any NZB file you download from an indexer’s website. See pricing.

Tips

  • Many indexers limit how many API calls and NZB downloads you can make each day. If searches stop working, you may have hit the limit.
  • Using two or three indexers gives you better coverage.
  • If a tab stays empty, check that the URL ends in /api (or whatever the site says) and that there are no spaces around your key.
