# Deepline Native: Free Company Bulk Lookup

> Free lookup of up to 1,000 companies in one call by domain, LinkedIn company URL or exact name. Includes inputs, outputs, SDK V2 examples, and Deepline cost.

Free lookup of up to 1,000 companies in one call by domain, LinkedIn company URL or exact name.

> [!NOTE]
>
> Tool ID: `free_company_bulk_lookup`

## 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(
  'free_company_bulk_lookup',
  {
    "domains": [
      "example.com"
    ],
    "linkedin_urls": [
      "https://www.linkedin.com/in/jane-doe"
    ],
    "company_names": [
      "Example Corp"
    ]
  },
);

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

### CLI

```bash theme={"languages":{"custom":["/languages/deepline-prompt.json"]}}
deepline tools execute free_company_bulk_lookup --input '{
  "domains": [
    "example.com"
  ],
  "linkedin_urls": [
    "https://www.linkedin.com/in/jane-doe"
  ],
  "company_names": [
    "Example Corp"
  ]
}' --json
```

## Example response

The static output schema lacks the details for a reliable example. Use `deepline describe free_company_bulk_lookup --json` for the complete live contract.

## Input reference

Look up to 1000 companies in the free company corpus in one call, by domain, LinkedIn URL or exact name. Returns one result per key, in request order: domains, then linkedin\_urls, then company\_names.
