## Endpoints

### get_work

Retrieve full metadata for a single academic work by its OpenAlex ID. Returns the reconstructed abstract, topics, concepts, referenced and related works, citation counts by year, bibliographic details, and open-access information. Accepts either a bare ID (W2741809807) or a full URL (https://openalex.org/W2741809807).

**Estimated cost:** Metered

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `work_id` | string | Yes | OpenAlex work ID (e.g., 'W2741809807' or full URL 'https://openalex.org/W2741809807'). |

```bash
curl -X POST https://api.paywithlocus.com/api/wrapped/parse-openalex-org-api-ad517f47/get_work \
  -H "Authorization: Bearer YOUR_LOCUS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"work_id":"<string>"}'
```

### search_works

Full-text search over OpenAlex's catalog of academic works. query matches title and abstract; sort orders results by any numeric field (cited_by_count, publication_date, relevance_score) with :asc or :desc suffix. filter narrows by facets (publication_year, type, is_oa, language) combinable with commas. Paginates via opaque cursor; first page uses '*'. Each returned work carries lightweight metadata — use get_work for full abstract, topics, concepts, and references.

**Estimated cost:** Metered

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `cursor` | string | No | Pagination cursor. Use '*' for the first page, then use next_cursor from the response for subsequent pages. |
| `filter` | string | No | Filter expression. Examples: 'publication_year:2024', 'type:article', 'is_oa:true', 'publication_year:2020-2024'. Multiple filters can be combined with commas. |
| `per_page` | integer | No | Results per page (1-200). |
| `query` | string | No | Full-text search query (e.g., 'machine learning', 'CRISPR gene editing'). Omitting returns all works. |
| `sort` | string | No | Sort order. Accepted values include 'cited_by_count:desc', 'cited_by_count:asc', 'publication_date:desc', 'publication_date:asc', 'relevance_score:desc'. Omitting uses default relevance ordering. |

```bash
curl -X POST https://api.paywithlocus.com/api/wrapped/parse-openalex-org-api-ad517f47/search_works \
  -H "Authorization: Bearer YOUR_LOCUS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"cursor":"<string>","filter":"<string>","per_page":"<integer>","query":"<string>","sort":"<string>"}'
