## What's an Apify Actor?

An Actor is a serverless cloud program that runs on the Apify platform. It has two run modes.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.

Apify vocabulary and the platform model are defined once, in the agent quickstart at https://apify.com/agents.md.

## 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.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For examples already wired to this Actor's own input schema, see the [API](#api) section below.

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).

# README

## Whatsapp Number Validator (Pay Per Result)

### Overview

This Apify Actor provides a robust and efficient solution for validating WhatsApp phone numbers. It allows you to quickly determine whether a given phone number has an active WhatsApp account, making it an invaluable tool for businesses, marketers, and developers. With its pay-per-result pricing model, you only pay for the successful validations (true / false), ensuring cost-effectiveness and transparency.

### Key Features

- ✅ **Accurate Validation:** Reliably checks if a phone number is registered on WhatsApp.
- 🚀 **Bulk Processing:** Efficiently validate multiple phone numbers in a single run.
- 💰 **Pay-Per-Result Pricing:** Only pay for successful validations (true/false), optimizing your budget.
- ⚡ **Fast Response Time:** Validate up to 19.200 numbers per minute with parallel processing.
- 🔌 **Simple Integration:** Easy to use with a straightforward input and output format.
- 🔒 **No WhatsApp Account Needed:** Unlike some providers, you don’t need to connect your own WhatsApp account or scan QR codes — everything works out of the box.

### Use Cases

- **Marketing Campaigns:** Clean your contact lists by removing invalid WhatsApp numbers, improving campaign efficiency and reducing bounce rates.
- **Customer Support:** Verify customer contact information to ensure seamless communication via WhatsApp.
- **Lead Generation:** Qualify leads by confirming their WhatsApp presence, enabling targeted outreach.
- **Data Enrichment:** Enhance your existing datasets with accurate WhatsApp availability information.

### How it Works

The Whatsapp Number Validator Actor takes a list of phone numbers as input. It then processes each number, checking for an active WhatsApp account. The output provides a clear indication of whether each number has WhatsApp, along with the original phone number.

### Pricing

This Actor operates on a pay-per-result model, ensuring you only pay for the value you receive.

- **$1 per 1000 Results.**

### Performance

Our tests indicate exceptional performance, allowing for high-volume validation:

- **Response Time:** Approximately only 10 seconds for 100 numbers per actor run.
- **Validation Rate:** Up to 19.200 number validations per minute.
- **Memory:** Only 128MB per actor RUN.

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,vtrdev/whatsapp-number-validator"

The hosted server signs you in with OAuth on first connect, so no API token belongs in this config. Clients without OAuth support can send an `Authorization: Bearer <APIFY_API_TOKEN>` header instead, using a token from API & Integrations in Apify Console (https://console.apify.com/settings/integrations).
