Find companies similar to a given seed domain. Optionally filter results by same country or same company size, and exclude companies from specific exclusion lists. Credit cost: 1 Finder credit per 10 results returned (rounded up).

- **Tool id:** `findymail-api-lookalike-search`
- **Provider:** [Findymail](/providers/findymail)
- **Job:** [Find companies similar to one you name](/reference/jobs/company-similar) (`company.similar`)
- **Price:** $0.0198 per call. A call that fails at the provider costs $0.

## Inputs

| Name | Type | Required | Description |
| --- | --- | --- | --- |
| `exclusion_list_ids` | array | no | IDs of exclusion lists to filter out already-known companies. |
| `limit` | integer | no | Maximum number of companies to return (default: 100, max: 10000). Example: 100 |
| `same_country` | boolean | no | Only return companies in the same country as the seed (default: false). Example: true |
| `same_size` | boolean | no | Only return companies in the same size range as the seed (default: false). Example: false |
| `seed` | string | yes | The seed company domain or URL. Example: "stripe.com" |

## Output

The run's `result` holds the provider's answer. Signed in, `looot inspect findymail-api-lookalike-search` prints its fields.

## Run it

Every call needs your API token in `LOOOT_TOKEN`; [Sign in](/get-started/sign-in#use-the-token-in-scripts-and-agents) shows how to get one. Each run also needs a new idempotency key, so a retry never pays twice. With `wait: 30` the answer comes back inline when the run ends within 30 seconds. Otherwise you get the running run back: poll `GET /v1/runs/<runId>`.

```js JavaScript
