# find_lookalike_companies

Find companies similar to one or more seed domains (for audience expansion).

Read [audiences](https://metadata.io/developers/tools/#cat-audiences)

## What it does

## Arguments

| Argument | Type |   | Notes |
|---|---|---|---|
| `domains` | array | required | Seed company domains, e.g. ['metadata.io']. |
| `limit` | integer |   | Max lookalikes to return (default 10). |

## Request

**Request template, not a complete runnable example.** Replace placeholders, empty objects, arrays, and zero values with valid account-specific inputs. Read required fields and nested constraints in the full schema. Confirm the account, connected channels, and referenced assets before calling a write tool.

## Response

Recorded with these arguments. Enum values are the first the tool's own schema declares; ids were fetched live from a `list_` call immediately before.

Real, from the production server, in **136 ms**. Values that identify a customer or disclose money are replaced with typed placeholders; keys, types and nesting are exactly as returned.
