## Run this action

Use the TypeScript SDK for one call. Use `ctx.tools.execute(...)` inside a Play for durable calls, scheduled calls, or CSV processing.

```ts theme={"languages":{"custom":["/languages/deepline-prompt.json"]}}
import { Deepline } from 'deepline';

const deepline = await Deepline.connect();
const result = await deepline.tools.execute(
  'theirstack_company_search',
  {
    "expand_technology_slugs": [],
    "order_by": [
      {
        "desc": true,
        "field": "confidence"
      },
      {
        "desc": true,
        "field": "num_jobs_found"
      },
      {
        "desc": true,
        "field": "num_jobs"
      },
      {
        "desc": true,
        "field": "num_jobs"
      },
      {
        "desc": true,
        "field": "employee_count"
      }
    ],
    "company_name_or": []
  },
);

console.log(result.toolResponse.raw);
```

### CLI

```bash theme={"languages":{"custom":["/languages/deepline-prompt.json"]}}
deepline tools execute theirstack_company_search --input '{
  "expand_technology_slugs": [],
  "order_by": [
    {
      "desc": true,
      "field": "confidence"
    },
    {
      "desc": true,
      "field": "num_jobs_found"
    },
    {
      "desc": true,
      "field": "num_jobs"
    },
    {
      "desc": true,
      "field": "num_jobs"
    },
    {
      "desc": true,
      "field": "employee_count"
    }
  ],
  "company_name_or": []
}' --json
```

## Example response

The SDK returns this shape at `result.toolResponse.raw`. The example values illustrate the response.

## Input reference

This endpoint lets you search for companies by technology stack, hiring signals, and firmographics. It returns a list of companies that match the search criteria, along with the jobs and technology objects for each company that match the filters you've passed. Useful resources: [Preview data mode](https://theirstack.com/en/docs/api/preview-data-mode), [Free count mode](https://theirstack.com/en/docs/api/free-count) The response includes both company data and any matching jobs or technologies based on your filters.

| Name | Type | Required | Default | Details |
| - | - | - | - | - |
| `payload.expand_technology_slugs` | `array` | No | `[]` | Specify technology slugs to include detailed technology usage information for each company. The response will include a 'technologies\_found' field containing metrics like confidence score, ranking, and job count for each specified technology. Note: If a technology is not listed for a company, it means that company does not use that technology. This feature is useful for enriching company data with their technology stack details. |
| `payload.order_by` | `array` | No | `[{"desc":true,"field":"confidence"},{"desc":true,"field":"num_jobs_found"},{"desc":true,"field":"num_jobs"},{"desc":true,"field":"num_jobs"},{"desc":true,"field":"employee_count"}]` | List of column objects. You can pass several columns to order by, in order of priority. Only `field` is required, `desc` is True by default |
| `payload.company_name_or` | `array` | No | `[]` | Only return companies that match these names exactly, case-sensitively. This filter acts as an OR filter, so if you pass more than one company name, it will return companies that match any of the names. |
| `payload.company_name_case_insensitive_or` | `array` | No | `[]` | Only return companies that match these names exactly, case-insensitively. |
| `payload.company_id_or` | `array` | No | `[]` | Only return companies that match these IDs exactly. This filter acts as an OR filter, so if you pass more than one company ID, it will return companies that match any of the IDs. |
| `payload.company_domain_or` | `array` | No | `[]` | Only return companies that match these domains exactly. It accepts full urls ([https://www.google.com/](https://www.google.com/)) and emails ([john.polo@gmail.com](mailto:john.polo@gmail.com)). This filter acts as an OR filter, so if you pass more than one company domain, it will return companies that match any of the domains. |
| `payload.company_domain_not` | `array` | No | `[]` | Only return companies that don't match these domains exactly. It accepts full urls ([https://www.google.com/](https://www.google.com/)) and emails ([john.polo@gmail.com](mailto:john.polo@gmail.com)). |
| `payload.company_name_not` | `array` | No | `[]` | Only return companies that don't match these names exactly, case-sensitively. |
| `payload.company_name_partial_match_or` | `array` | No | `[]` | Company names. Will return companies whose name contain any of the the substrings passed here, case-insensitively. For example, if you pass "google", it will return "Google", "Google LLC", "Google Inc", etc. |
| `payload.company_name_partial_match_not` | `array` | No | `[]` | Company names. Will return companies whose name doesn't contain any of the the substrings passed here, case-insensitively. For example, if you pass 'google', it will exclude 'Google', 'Google LLC', 'Google Inc', etc. |
| `payload.company_linkedin_url_or` | `array` | No | `[]` | Return companies whose LinkedIn URL matches any of the slugs passed here. Can also pass full LinkedIn company URLs. |
| `payload.blur_company_data` | `boolean` | No | `false` | Return blurred company and job fields for preview. Free preview availability depends on workspace eligibility, and preview is unavailable when filtering by company identifiers (company\_name, company\_domain, company\_linkedin\_url, company\_id). Count-only searches are still billable by Deepline: when include\_total\_results=true and limit=1, each returned result is billed even if this flag is true. Learn more at [https://theirstack.com/en/docs/api/preview-data-mode](https://theirstack.com/en/docs/api/preview-data-mode). |
| `payload.property_exists_or` | `array` | No | `[]` | Return companies that have any of these fields not null. For example, if you pass \['domain', 'linkedin\_url'], it will return companies that have a domain OR a linkedin\_url set. |
| `payload.property_exists_and` | `array` | No | `[]` | Return companies that have all of these fields not null. For example, if you pass \['domain', 'linkedin\_url'], it will return companies that have both domain AND linkedin\_url set. |
| `payload.offset` | `integer` | No | `0` | Number of results to skip. Required for [offset-based pagination](https://theirstack.com/en/docs/api-reference/pagination). Minimum: 0. |
