Enrichley API overview

Enrichley helps you recover valid emails that other verification tools discard, especially catch-all and other “risky” emails. On average, 40–60% of unverified lists contain catch-all emails, and Enrichley’s verification is built to recover as many of these as possible—often resulting in 20–30% more valid emails on the same lists.

Authentication

All requests are authenticated with an API key via the X-Api-Key header:

API keys are generated automatically when you sign up for a paid plan in the Enrichley app. Once you have a paid plan, your API key works across all Enrichley APIs.
