mailsurity on npm
We just shipped two new things. mailsurity on npm - a zero-dependency, MIT-licensed TypeScript client for our disposable-email detection API. `npm i mailsurity`, drop in your API key, and `checkEmail()` / `isDisposable()` are ready to call from any server-side Node 18+ runtime (edge included). It fails open by default, so an outage on our end never blocks a real signup - pass `failOpen: false` if you'd rather catch errors yourself. Integration guides for the stacks people actually run: Next.js, Clerk + Supabase Auth, Auth0 (Pre User Registration Action), Vercel, and ConvertKit/Beehiiv webhooks. Each one is working code you can paste in, not just API reference. Still 500 free credits, no card required, so you can try it on real signups today. npm: https://www.npmjs.com/package/mailsurity Guides: https://www.mailsurity.com/guides
