NumRadar - Showcase Project

NumRadar helps teams choose the right channel before messaging a customer. NumRadar answers one question: is this phone number registered on WhatsApp? Teams that already hold customer and lead lists use it before a campaign, an order update, an appointment reminder or a first outreach, so they know which contacts to reach on WhatsApp and which need SMS, email or a call. There are four ways to check, all on one account and one monthly allowance. Upload a CSV or Excel file in the dashboard: NumRadar finds the phone column, removes duplicates and lets you download the results as CSV or JSON. Call POST /v1/validate from your own software and get JSON back in roughly 300 to 800 milliseconds. Connect an AI agent to the hosted MCP server. Or use the Chrome extension to check the numbers on a CRM page or a directory you already have open. Each result says whether the number is registered, whether it is a business account and its profile name, the line type, the country and a wa.me chat link. You never connect a WhatsApp number, a Business account or a Cloud API app. Billing follows the answer. Registered and not registered each use one validation. Invalid numbers and lookups that could not finish cost nothing, and an unfinished lookup comes back as Unknown, never as not registered. Bulk lists and their results are deleted 30 days after the job ends. Plans run from Starter at USD 9 a month for 5,000 validations to Enterprise at USD 249 for 300,000. Monthly USD plans: $9 for 5,000 validations, $29 for 25,000, $99 for 100,000, and $249 for 300,000. Product demo: https://www.youtube.com/watch?v=Fo8FShnIMJw
