    Torrin's HTTP API has two halves:


    - The **native app API** under `/api` — the job engine, search,
    availability,
      bring-your-own-key debrid, bring-your-own-storage, Usenet, Cairn, and RSS. This is
      "torrin's own API"; it takes and returns torrin's own JSON.
    - Two **compatibility surfaces** for existing clients: a
    **RealDebrid-compatible** API
      under `/rest/1.0` (Stremio RD addons) and a **StremThru store** API under `/v0/store`
      (clients like Comet).

    All authenticated endpoints use your instance **API key** as a bearer token.
