## Introduction

Target contacts by their company's 4-digit SIC code. Prefix with `-` to exclude a code. Combine it with any other filter in the same request (AND logic).

## AI agent prompt

```text theme={null}
Read https://docs.seamless.ai/api-catalog/contact-filters/sic-code. Using SEAMLESS_API_KEY, call POST https://api.seamless.ai/api/client/v1/search/contacts with the `industrySicCodes` filter to find contacts matching: <your target>. Page with nextToken and keep each searchResultId.
```

## Example

```bash cURL theme={null}
curl -X POST https://api.seamless.ai/api/client/v1/search/contacts \
  -H "Token: $SEAMLESS_API_KEY" -H "Content-Type: application/json" \
  -d '{"industrySicCodes": ["7372"], "limit": 25}'
```

```python Python theme={null}
import os, requests
rows = requests.post("https://api.seamless.ai/api/client/v1/search/contacts",
    headers={"Token": os.environ["SEAMLESS_API_KEY"]},
    json={"industrySicCodes": ["7372"], "limit": 25}).json()["data"]
```

## Reference

| Parameter | Type | Required | Description |
| - | - | - | - |
| `industrySicCodes` | string\[] | Yes | Filter contacts by their company's SIC code. Applied independently of `industry`, so the two can be combined or used on their own. Prefix a value with `-` to exclude it. Up to 5 codes can be specified. |
| `limit` | integer | No | Results per page, up to 500. Default `50`. |
| `nextToken` | string | No | Cursor from `supplementalData.nextToken` to fetch the next page. |

## Response

Rows are contact previews with `searchResultId`, name, title, seniority, company, location, and LinkedIn URL, but no emails or phones. Send `searchResultId` to [Contact Research](/api-catalog/contact-enrichment) to get them. Fields: [Contact Search](/api-catalog/contact-search).

Auth: `Token` header ([API keys](/authentication/api-keys)) · Errors: [status codes](/api-http-status-codes) · Billing: [rate limits and credits](/rate-limits-and-credits)
