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.
