Every call goes through the unified Run API: send the API `slug`, the endpoint `path`, and the `query`/`body` parameters. The response is `{ "success": true, "price": "<usd>", "data": { ... } }`.

## Endpoints

### Find Company Employees

List employees of a given company. Returns paginated results. The company_uid path parameter is the LinkedIn company ID (e.g., 1035 for Microsoft), which can be obtained from the Enrich Company or Find Company endpoints (li_company_id field). Pagination billing: call the first page normally and save billing.requestId from the Orthogonal /v1/run response. For later page, offset, or cursor calls on the same logical search, pass parentRequestId with unchanged non-pagination parameters. Valid continuation calls still get their own request IDs and quoted price, but are charged 0. Changing filters starts a new billable request.

`GET /companies/{company_uid}/employees`

**Estimated cost:** $2.29
