Use DMM as a torrent indexer

The torrent indexer answers Prowlarr, Sonarr and Radarr as a Torznab indexer backed by DMM's own library, so your *arr stack can search it like any other tracker and hand the magnets to your debrid account. The whole setup is written out below; the one thing it needs that this browser does not have yet is a DMM API key, which comes with a sponsorship.

Get your key by connecting your GitHub account there, then paste it in Settings to link this browser. Already sponsoring on another machine? It is the same key on this one, so there is nothing to pay twice.

Prowlarr: Settings → Indexers → + → Torznab (the generic one). Sonarr and Radarr take the same three values under Settings → Indexers → + → Torznab if you would rather skip Prowlarr.

A title nobody has looked up yet is scraped while your search waits, so an empty first answer is worth repeating once before blaming the indexer.

Nothing here comes off a swarm, so seeders is repurposed: a release your debrid account can grab instantly comes back as 100 seeders, and everything else as 1. Prowlarr, Sonarr and Radarr rank on that number, so the plain URL already puts what you can actually grab at the top. Most people need nothing below this line.

If you want more than ranking, the URL takes two optional parts, in this order:

Without it the feed carries everything and the seeder count does the sorting. With it, anything that cache does not already hold is left out of the feed entirely — use it when you would rather import nothing than wait on a download.

Remember an *arr appends /api itself, so what you paste into the URL field is the line above and nothing more.

Map the parent categories rather than only the subcategories: a release whose name never states a resolution is labelled 2000 or 5000 and nothing else, so a HD-only mapping hides it.

Counted against your DMM API key, not your IP, so several *arr instances behind one key share the budget. Cap Prowlarr's RSS sync interval rather than letting a full library search run unthrottled.

Every result is a magnet link, so point your *arr at any download client that adds magnets to your debrid account. DMM is not in that path at all — it hands over the infohash and your own account does the rest.
