**Category:** Music | **Website:** [tunebat.com/](https://tunebat.com/) | **Docs:** [parse.bot/marketplace/90a1cbfb-2f67-42ac-b028-33f15136ab7e/tunebat-com-api](https://parse.bot/marketplace/90a1cbfb-2f67-42ac-b028-33f15136ab7e/tunebat-com-api)

Pay-per-use API proxy for Locus Pro. Each call burns credits from your workspace balance.

## Access

**Base URL:** `https://api.paywithlocus.com/api/wrapped/credits/tunebat/`
**Auth:** `Authorization: Bearer <LOCUS_CREDITS_SECRET_KEY>` (an `lcr_` secret key or a scoped `lcac_` agent credential)
**Required header:** `Idempotency-Key: <fresh UUID per call>`. A retry with the same key replays the stored result without a new charge.
**Response:** the provider response after any endpoint-specific normalization. `X-Locus-Credits-Charged` carries the charge and `X-Locus-Credits-Balance` the remaining balance. Insufficient credits return `402` before the provider is called.
**Pricing:** estimated costs below are USD. Locus debits the credit equivalent at your workspace rate.

> Using a Pay With Locus wallet key (`claw_` prefix)? Wallet routes are documented separately: https://docs.paywithlocus.com/wrapped-apis/for-agents

## Endpoints

### Get track details

Retrieve detailed audio features and metadata for a single track by its Spotify/Tunebat track ID or full Tunebat Info URL. Returns key, BPM, Camelot notation, duration, album, release date, and numeric audio features (energy, danceability, happiness, acousticness, instrumentalness, liveness, speechiness, loudness, popularity). At least one of track_id or track_url must be provided; if both are given, track_url takes precedence.

**Estimated cost:** Metered

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `track_id` | string | No | Spotify/Tunebat ID of the track (e.g., '7qiZfU4dY1lWllzX7mPBI3') |
| `track_url` | string | No | Full Tunebat Info URL of the track (e.g., 'https://tunebat.com/Info/Shape-of-You-Ed-Sheeran/7qiZfU4dY1lWllzX7mPBI3') |

```bash
curl -X POST https://api.paywithlocus.com/api/wrapped/credits/tunebat/get-track-details \
  -H "Authorization: Bearer $LOCUS_CREDITS_SECRET_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
  -d '{"track_id":"<string>","track_url":"<string>"}'
```

### Search tracks

Full-text search over Tunebat's track catalog by keyword (song name, artist, etc.). Returns up to 50 results per call with basic metadata (name, artist, track_id, url). The total_available field reports how many matches exist server-side. Each result's track_id can be passed to get_track_details for full audio features. Note: the upstream API may intermittently return 500 errors for some queries due to backend rate limiting.

**Estimated cost:** Metered

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `query` | string | Yes | Search keyword (e.g., 'classical', 'jazz', 'guitar', 'coldplay', 'ed sheeran') |

```bash
curl -X POST https://api.paywithlocus.com/api/wrapped/credits/tunebat/search-tracks \
  -H "Authorization: Bearer $LOCUS_CREDITS_SECRET_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
  -d '{"query":"<string>"}'
```
