# kindexr

A Nostr-native Torznab indexer. Subscribes to NIP-35 torrent events on the Nostr relay network and serves them through the Torznab API that Sonarr, Radarr, Lidarr, Readarr, and Prowlarr already speak.

**Same slot as Jackett or Prowlarr** — middleware between Nostr and the *arr automation stack. Not a frontend, not a relay, not a downloader.

## What it does

- Connects to Nostr relays and indexes kind 2003 (NIP-35) torrent events into a local SQLite database
- Serves indexed content as a Torznab API endpoint for *arr apps
- Enriches metadata via TMDB (movies and TV shows get proper IDs for *arr matching)
- Filters publishers using Web of Trust (WoT) — trust scores derived from your Nostr follow graph, with manual vouch/block/mute controls
- Optionally publishes torrents back to Nostr from a connected qBittorrent instance
- Fetches publisher profiles (kind 0) so you see names and avatars instead of raw pubkeys
- Web UI at `/ui` — dashboard, indexed content browser, publisher management, publish queue


## Quick start

### Build

```sh
just build
# produces target/release/kindexr and target/release/kindexr-cli
```

### Configure

```sh
sudo mkdir -p /etc/kindexr /var/lib/kindexr
sudo cp deploy/kindexr.example.yaml /etc/kindexr/config.yaml
sudo $EDITOR /etc/kindexr/config.yaml
```

Create the service user:

```sh
sudo useradd --system --no-create-home --shell /usr/sbin/nologin kindexr
sudo chown kindexr:kindexr /var/lib/kindexr
```

### Install and start

```sh
sudo just install
sudo systemctl daemon-reload
sudo systemctl enable --now kindexr
sudo journalctl -u kindexr -f
```

### Verify

```sh
curl http://localhost:9117/health
# {"status":"ok","version":"...","db_ok":true,"relays_configured":3,"relays_connected":3,"uptime_seconds":0}
```

### Add to Sonarr/Radarr

Add kindexr as a Torznab indexer:

- URL: `http://127.0.0.1:9117` (or your public URL behind nginx)
- API key: generate with `kindexr-cli apikey create --label sonarr`

## CLI

```sh
# API key management
kindexr-cli apikey create --label sonarr
kindexr-cli apikey list

# Publisher identity (for publishing back to Nostr)
kindexr-cli identity init           # generate a fresh keypair
kindexr-cli identity init --nsec <nsec1...>  # import existing key
kindexr-cli identity info

# Enqueue torrent files for publishing
kindexr-cli publish --from /path/to/torrents/
```

## Configuration

See `deploy/kindexr.example.yaml` for a fully commented configuration reference.

Config is loaded in order: **defaults → YAML file → environment variables** (`KINDEXR_` prefix).

Example env override:

```sh
KINDEXR_LOGGING_LEVEL=debug kindexr --config /etc/kindexr/config.yaml
```

## Development

```sh
just test    # cargo test
just check   # cargo clippy + fmt check
just build   # cargo build --release
```

For a local dev run without installing:

```sh
cp deploy/kindexr.example.yaml kindexr.dev.yaml
# edit kindexr.dev.yaml — set database.path to /tmp/kindexr-dev.db, disable publisher
./target/release/kindexr --config kindexr.dev.yaml
# UI at http://localhost:9117/ui
```
