## Useful jq Filters

For JSON processing, see the [jq skill on ClawdHub](https://clawdhub.com/skills/jq).

```bash
# Recent tracks: artist - track
jq '.recenttracks.track[] | "\(.artist["#text"]) - \(.name)"'

# Top artists: name (playcount)
jq '.topartists.artist[] | "\(.name) (\(.playcount))"'

# Check if currently playing
jq '.recenttracks.track[0] | if .["@attr"].nowplaying == "true" then "Now playing: \(.artist["#text"]) - \(.name)" else "Last played: \(.artist["#text"]) - \(.name)" end'
```

## Notes

- No auth needed for read-only endpoints (just API key)
- Rate limit: be reasonable, no hard limit documented
- URL-encode artist/track/album names (spaces → `+` or `%20`)
- Images come in sizes: small, medium, large, extralarge
