## Authentication

Send `Authorization: Bearer gtk_…`. Create the key under **API Access → API Keys**. A missing, invalid or revoked key is **401**, including while this API is closed. A valid key while the API is closed for your organization answers **404**, the same body as an unknown path. Every response includes `FounderMCP-Api-Version` and `FounderMCP-Request-Id`.

### Query parameters

- **`q`** `string` · **required** — The company name, 2 to 200 characters.

## Response

- **`object`** `string` · **required** — Always `list`. One of: `list`.
- **`data`** `object[]` · **required** — Up to five pages.
- **`data[].name`** `string` · **required** — Page name.
- **`data[].linkedin_url`** `string` · **required** — The company page URL.
- **`data[].subtitle`** `string | null` — The line under the name, when the page has one.
- **`data[].exact`** `boolean` · **required** — True when the name matches exactly.

## Credits

Free. This call never uses credits. It is limited to 10 requests per minute per key, tighter than the other endpoints.

## Errors

- **400** `invalid_request` — `q` is missing or shorter than 2 characters.
- **401** `authentication_error` — The Authorization header is missing, or the key is unknown or revoked.
- **403** `permission_error` — API access is not part of your plan, or your account is suspended.
- **404** `not_found` — The endpoint does not exist.
- **429** `rate_limit_error` — More than 60 requests per minute, or more than 3 at the same time, on one key. Wait for the Retry-After header.
- **500** `internal_error` — Something went wrong on our side.
