One API call. Sub-50ms response. 200K+ disposable domains tracked and growing. Built for developers who ship fast.
$ curl https://api.notemp.email/v1/checkAddress \-H "x-api-key: YOUR_API_KEY" \--json '{"email": "user@tempmail.com"}'# → {"isTemp": true}
Most disposable email blockers ship a fixed list of domains and call it a day. New providers launch every week — and they slip right through. NoTemp is different.
Our scrapers continuously crawl the internet for new disposable email providers the moment they appear — not months later when someone updates a GitHub list.
We don't just track domains. We discover individual throwaway addresses and new domains from known providers as they rotate their infrastructure.
Our database grows every hour. Existing providers get monitored for new domains and aliases. New providers get added the day they launch.
POST a JSON payload with the email address to /v1/checkAddress. That's it.
The address is matched against our full database — exact addresses first, then the domain. Both layers scraped and refreshed around the clock.
You get back {"isTemp": true | false} in under 50ms. Block, flag, or route — your call.
