# Count Companies

> Count the companies that match a set of filters, free of charge.

Requires an API key with the `read` scope.

Counting does not use the daily search budget and does not spend reveal credits. It needs a paid plan. Company filters have their own keys; see `companyFilterKeys` in [Get Filter Options](/api-reference/lead-finder/get-filter-options).

## Body Parameters

<ParamField body="filters" type="object" required>
  Company filters, for example `{"industries": ["Computer Software"], "minHeadcount": 50, "countries": ["US"]}`. At least one filter besides `countries` is required.
</ParamField>

## Response

<ResponseField name="data" type="object">
  Result.

  <Expandable title="data">
    <ResponseField name="total" type="integer">Number of matching companies.</ResponseField>
  </Expandable>
</ResponseField>

## Errors

| Status | Description |
|--------|-------------|
| `401` | Missing, invalid, revoked or expired API key |
| `403` | API key does not have the required scope: `read` |
| `400` | `country_not_available` when a requested country is outside the covered list (`{"detail": {"code": "country_not_available", "message": "...", "allowed": [], "blocked": []}}`); `unknown_filter_keys` naming each key that does not exist (`{"detail": {"code": "unknown_filter_keys", "message": "...", "unknownKeys": [], "validKeys": []}}`); or a message asking for at least one filter besides `countries` |
| `403` | `upgrade_required` on the Free plan: `{"detail": {"code": "upgrade_required", "limit_type": "lead_finder", "message": "..."}}`. A missing scope also returns 403 with a plain `detail` string |
| `404` | `Lead Finder is not enabled` while Lead Finder is switched off on this environment |
| `502` | `The data provider is unavailable right now` |
| `503` | `Lead Finder is not configured` when it is enabled but has no data provider key |

## Rate Limit

- **100 requests per minute, per API key.** Fixed 60-second window.
- Every response includes `X-RateLimit-Limit`, `X-RateLimit-Remaining`, and `X-RateLimit-Reset` (unix epoch seconds).
- A `429` response includes a `Retry-After` header (seconds until the bucket resets).

For client-side patterns (`Retry-After`, exponential backoff, monitoring `X-RateLimit-Remaining`), see [Rate Limiting](/rate-limiting).
