## About

NumRadar helps teams choose the right messaging channel by checking whether phone numbers are registered on WhatsApp. Bulk validate phone-number data in a few clicks, integrate the real-time REST API, or let an AI agent do the work through MCP in a sentence. The Chrome extension checks numbers you find online.

Plans start at $9 USD/month for 5,000 validations, scaling to $29 for 25,000, $99 for 100,000 and $249 for 300,000 monthly validations. Every plan includes the dashboard, API, MCP and Chrome extension. No WhatsApp account connection is required.

Validation checks registration; it does not send messages or establish permission to contact someone.
