### get_painting

Get detailed information about a single painting by its URL slug. Returns metadata including title, artist, dates, medium, dimensions, location, and a description.

**Estimated cost:** Metered

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `slug` | string | Yes | URL slug of the painting (e.g. 'claude-monet-still-life'). Obtainable from search_paintings results. |

```bash
curl -X POST https://api.paywithlocus.com/api/wrapped/parse-nationalgallery-org-uk-api-b7466f2a/get_painting \

  -d '{"slug":"<string>"}'
```

### search_paintings

Search the National Gallery collection by keyword. Results include title, artist, date, location, and a brief overview. The upstream API has no stateless pagination mechanism (it requires tracking viewed item IDs); use the limit parameter to control how many results are returned in a single request (up to ~100).

|-------|------|----------|-------------|
| `limit` | integer | No | Maximum number of paintings to return per request (up to ~100). |
