**Category:** Education | **Website:** [www.huntington.org/collections/search](https://www.huntington.org/collections/search) | **Docs:** [parse.bot/marketplace/282ee7f6-bdf3-466a-8d16-d3dd4722e10a/huntington-org-api](https://parse.bot/marketplace/282ee7f6-bdf3-466a-8d16-d3dd4722e10a/huntington-org-api)

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

## Access

**Base URL:** `https://api.beta.paywithlocus.com/api/wrapped/credits/huntington/`
**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 facets

Get available facet values and counts for filtering collections. Returns counts for divisions, item types, genera, families, authors, and constituents, optionally scoped to a search query or division. Useful for discovering filter options before searching.

**Estimated cost:** Metered

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `division` | string | No | Filter facets by division: 'library', 'museum', or 'botanical' |
| `query` | string | No | Optional search query to scope facet counts |

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

### Search collections

Search The Huntington's collections by keyword with optional filters for division, item type, and image availability. Returns paginated results with item details including name, description, division, type, identifier, and image URL. Each page returns up to `limit` items; advance `page` (0-indexed) to paginate. An empty query returns all items in the matching scope.

**Estimated cost:** Metered

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `division` | string | No | Filter by division: 'library', 'museum', or 'botanical' |
| `has_image` | string | No | Set to 'true' to only return items with images |
| `limit` | integer | No | Results per page, clamped to 1-100 |
| `page` | integer | No | Page number (0-indexed) |
| `query` | string | No | Search keywords (e.g., 'William Blake', 'rose', 'painting') |
| `type` | string | No | Filter by item type (e.g., 'Paintings', 'Rare Books', 'Manuscripts', 'Plants', 'Drawings', 'Sculpture', 'Prints', 'Visual Materials', 'Decorative arts', 'Photographs') |

```bash
curl -X POST https://api.beta.paywithlocus.com/api/wrapped/credits/huntington/search-collections \
  -H "Authorization: Bearer $LOCUS_CREDITS_SECRET_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
  -d '{"division":"<string>","has_image":"<string>","limit":"<integer>","page":"<integer>","query":"<string>","type":"<string>"}'
```
