**Category:** Music | **Website:** [spitfireaudio.com/](https://spitfireaudio.com/) | **Docs:** [parse.bot/marketplace/d28655c1-8d13-4885-a394-a5db098f6a1c/spitfireaudio-com-api](https://parse.bot/marketplace/d28655c1-8d13-4885-a394-a5db098f6a1c/spitfireaudio-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/spitfireaudio/`
**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.

Full call contract: https://docs.paywithlocus.com/api-reference/introduction

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

## Endpoints

### Get library details

Get detailed information for a specific sample library by its handle (URL slug). Returns the full HTML description, pricing in GBP, images, system requirements parsed from the product page, and aggregated Trustpilot user reviews including individual review content and ratings. The handle is the slug returned by list_libraries.

**Estimated cost:** Metered

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `handle` | string | Yes | The unique handle/slug for the library, as returned by list_libraries (e.g. 'albion-one', 'bbc-symphony-orchestra'). |

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

### List libraries

List all sample libraries available on the Spitfire Audio store. Returns every product aggregated across paginated results (up to 20 pages). Each library includes basic metadata: title, handle, vendor, price, SKU, and tags. Use a library's handle to fetch full details via get_library_details.

**Estimated cost:** Metered

_No parameters required._

```bash
curl -X POST https://api.paywithlocus.com/api/wrapped/credits/spitfireaudio/list-libraries \
  -H "Authorization: Bearer $LOCUS_CREDITS_SECRET_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
