# Clean a phone number list before a cold-calling campaign

**Use case:** 

Validate phone numbers before a cold-call or SMS campaign so you never dial a dead line. Get number type. $2 per 1,000 checked, free for invalid ones.

{
  "phoneNumbers": [
    "4155552671",

## About this Actor

This example demonstrates how to use [Phone Number Validator](https://apify.com/accountable_eel/phone-number-validator.md) with a specific input configuration. Visit the [Actor detail page](https://apify.com/accountable_eel/phone-number-validator.md) to learn more, explore other use cases, and run it yourself.


## 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).
