API reference

Trackarr exposes three surfaces:

1. Tracker endpoints — apps/tracker (Go). Public, anonymous, BEP-spec'd. /announce over HTTP and UDP.
2. REST API — apps/api (Nitro). Everything under /api/*. Session-cookie auth.
3. Torznab + RSS — feed-style endpoints for *Arr clients and feed readers, keyed by passkey or Torznab API key.

The lists below are curated, not exhaustive: they cover the surfaces an integrator or an operator reaches for, with the notes a generator cannot write. The complete, always-current inventory is generated from the route tree itself and served by the running instance:

GET /api/docs/openapi.json      # every path, method, guard and shared schema

apps/api/scripts/generate-openapi.mjs derives it from the filenames, so a path cannot exist without appearing there, nor appear without existing. Whole subsystems (messaging, federation, themes, presentation templates, tickets, site statistics) are documented in their own guides and in that document rather than duplicated here.

Auth labels: public (anonymous), user (any authenticated user), mod (canModerate permission), admin (admin role), passkey (announce-style, passkey in URL).

Tracker endpoints

The Go tracker speaks two protocols off the same backend.

HTTP announce (BEP 3) — GET /announce

GET /announce?info_hash=...&peer_id=...&port=...
            &uploaded=...&downloaded=...&left=...
            &event=started|completed|stopped&numwant=...&compact=1

Passkey is read from the path (/announce/PASSKEY) or the ?passkey= query parameter. Response is the standard bencoded peer list.

UDP announce (BEP 15) — :6969/udp

Stateless connect-then-announce. Passkey extracted from the BEP 41 URL_DATA option. See UDP Tracker for the wire format, connection-id HMAC scheme, and reverse-proxy caveats.

No /scrape, no wss://

The tracker does not currently implement a multi-hash scrape endpoint or the WebTorrent (WebSocket) announce path. Don't advertise a wss:// URL or a scrape URL in .torrent files — clients will hang.

Refused when the two differ on the adult flag, when the target descends from the source, or when a category with children would land under a non-root.
POST	/api/admin/tags	Create a tag.
DELETE	/api/admin/tags/:id	Delete a tag (unbinds it from every torrent in the same transaction).

Rate limits

The API enforces sliding windows in Redis. Limits are tuned in apps/api/utils/rateLimit.ts and are not env-driven today.

Bucket	Limit	Window
Public read	100 req	1 min
Mutations (POST/PUT/PATCH/DELETE)	10 req	1 min
Auth (/api/auth/*)	5 req	5 min
Tracker announce	200 req	1 min

Exceeding a bucket returns 429 Too Many Requests. Repeated offences within a short window add a temporary IP ban — see Security.

Error shape

Every error response uses h3's default shape:

{
  "url": "/api/example",
  "statusCode": 429,
  "statusMessage": "Too Many Requests",
  "message": "Rate limit exceeded",
  "data": {}
}

Common status codes:

Code	Meaning
400	Validation failed (Zod body / query schema).
401	Not authenticated (no session cookie).
403	Authenticated but lacking the required permission/role.
404	Resource not found, OR (deliberate) hidden — see Moderation thread.
409	Conflict (e.g. duplicate info_hash on upload, role-rule collision).
429	Rate limited.
500	Server error — surface to the operator via LOG_LEVEL=error.
