## README

### Facebook Company Search API

Search the Meta Ad Library for advertisers by keyword and get matching pages: page ID, category, verification, follower counts, and linked Instagram.

#### Request

```bash
curl -X POST "https://api.sandbase.ai/v1/run" \
  -H "Authorization: Bearer $SANDBASE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model": "facebook/search-companies", "query": "nike"}'
```

The result is returned in `outputs[0].data`. A lookup that finds nothing still succeeds and returns `found: false`.

#### Parameters

| Name | Type | Required | Description |
|---|---|---|---|
| `query` | string | Yes | Keyword to search advertiser pages for (e.g. "nike"). |

#### Pricing

Billed at the actual cost of each call, usually $0.0011 per request. A call can cost more when the first data source fails and another one answers. Failed calls are not charged. Lookups that find nothing and searches with no results are billed at their actual cost, which is often lower and can be $0.
