# Find decision makers

`POST /api/v1/contacts/lookup/decision-makers`

Authentication: API key.

Find decision makers at a company using LeadMCP database search. Matches contacts with seniority `C-Team`, `VP`, or `Director`, or any job title containing `Head` (e.g. Head of Growth, Department Head). Provide exactly one of `domain`, `company_name`, or `linkedin_company_url`. Always returns contacts with `VALID` emails. `require_email` is accepted but ignored. Up to 5000 records per request (default 5000); use `offset` for the next page. 1 credit per record returned; 0 if none. The response echoes the applied `role_filter`.

### Body parameters

| --- | --- | --- | --- | --- |
| `domain` | string | no |  |  |
| `limit` | number | no |  |  |
| `offset` | number | no |  |  |
