# Build a B2B leads list from a domain list

**Use case:** 

Paste the domains you already qualified and get one row per company: role emails, phone numbers and social profiles. Companies that publish nothing come back saying so, which is more useful than a guessed address that bounces and costs you sender reputation.

## Input

```json
{
  "domains": [
    "https://basecamp.com",
    "https://linear.app",
    "https://mollie.com"
  ],
  "includePersonal": false,
  "maxConcurrency": 3,
  "proxy": {
    "useApifyProxy": false
  }
}
```

## Output

```json
{
  "success": {
    "label": "Success",
    "format": "boolean"
  },
  "domain": {
    "label": "Domain",
    "format": "string"
  },
  "roleEmails": {
    "label": "Role emails",
    "format": "array"
  },
  "personalEmails": {
    "label": "Personal emails",
    "format": "array"
  },
  "phones": {
    "label": "Phone numbers",
    "format": "array"
  },
  "socials": {
    "label": "Social profiles",
    "format": "array"
  },
  "emailCount": {
    "label": "Email count",
    "format": "integer"
  },
  "errorCode": {
    "label": "Error code",
    "format": "string"
  }
}
```

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.
This Task's input is already configured above — use it as-is rather than inventing a new one.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).
