## Bulk collect endpoints

Bulk Collect is an extension of Base Company API and includes **three POST** and **two GET** endpoints.

Collect company data in bulk using an ID list, search filters, or Elasticsearch DSL schema that is already used in the Base Company API.

| Request type | Endpoint                                                    |
| ------------ | ----------------------------------------------------------- |
| POST         | */v2/data\_requests/company\_base/id\_file*                 |
| POST         | */v2/data\_requests/company\_base/filter*                   |
| POST         | */v2/data\_requests/company\_base/es\_dsl*                  |
| GET          | */v2/data\_requests/{data\_request\_id}/files*              |
| GET          | */v2/data\_requests/{data\_request\_id}/files/{file\_name}* |

### Limiting the returned record count

Include the parameter `"limit": int` to control the number of records returned by your queries in `/v2/data_requests/company_base/filter` and `/v2/data_requests/company_base/es_dsl` endpoints.

**Request example to retrieve five records**

{% code title="Search filters example" %}

```json
curl -X 'POST' \
  'https://api.coresignal.com/cdapi/v2/data_requests/company_base/filter' \
  -H 'accept: application/json' \
  -H 'apikey: {API Key}' \
  -H 'Content-Type: application/json' \
