# Similar companies

> Find competitors and lookalikes of a company, by its domain.

`company_similar` finds companies similar to one you name by its domain: competitors and lookalikes, with the same [company fields](https://clonvo.com/docs/company-search.md#company-fields) as `company_search`. To find similar web pages instead, use [`find_similar`](https://clonvo.com/docs/find-similar.md).

Call it with `POST /v1/tools/company_similar`, or as `company_similar` over [MCP](https://clonvo.com/docs/mcp.md).

## Arguments

-   `domain` string Required
    
    The company’s website domain, e.g. stripe.com. Use a bare domain such as example.com (no scheme, path or wildcard).
    
-   `max_results` integer
    
    How many companies to return (1–25, default 10).
    

## Example

```bash
curl https://api.clonvo.com/v1/tools/company_similar \

  -H "Content-Type: application/json" \

## Result

| Field | Description |
| --- | --- |
| `domain` | The domain you asked about. |
| `companies[]` | Similar companies, each with the [company fields](https://clonvo.com/docs/company-search.md#company-fields). |
| `notes` | Present when the provider handled an argument differently. |

The fields around `result` (`id`, `tool`, `provider`, `usage`) are the same for every tool; see [Calling tools](https://clonvo.com/docs/calling-tools.md#response).

## Notes

-   Results can differ slightly between providers, and field coverage depends on the provider that served the call. `notes` says when an argument was handled differently.
-   Clonvo never returns email addresses or phone numbers, even when a provider sends them.
