Validate WhatsApp numbers in real-time, before you send

1 follower

Wavalid checks whether a phone number is on WhatsApp in under 100ms, across 195+ countries. Pull it into your stack through a REST API, MCP server, dashboard, or Chrome extension. Cold outreach teams and SaaS onboarding flows use it to stop messaging dead numbers. Pricing is credit-based, with no subscription lock-in. Each call cleans your list a little more, so bounce rates and messaging costs drop too.

Hey Product Hunt I built Wavalid because I kept sending WhatsApp campaigns into dead numbers and wasting credits on tools that guess instead of check. Wavalid does a real-time lookup, sub-100ms, 195+ countries, so you know before you send. It's live as a REST API, an MCP server for your AI agents, a dashboard, and a Chrome extension. Would love your feedback, especially on pricing and what integrations you'd want next.
