Quickstart

Sign up for a free account to get your API key. No credit card required. You get 1,000 free verifications to test with real traffic.

Once you have your API key, make a single verification request to the /verify endpoint. The API returns a verdict — VALID, DISPOSABLE, RISKY, or UNDELIVERABLE — plus a 0–100 deliverability score in under 300ms.

From here, explore the API reference for advanced parameters, the webhook guide for real-time signup protection, or the SDK docs for your language.
