Email API

Format, domain, role, and a typo suggestion, on every call.

Pass an email address up to 254 characters. Malformed addresses return 400 invalid_request. A successful lookup returns format, domain, and role flags and counts as a normal request. The valid field does not establish mailbox deliverability.

Disposable is included on every call. didyoumean is a suggested address when the host looks like a known misspelling, or null. Deliverable and catchall live behind ?deep=true. Those calls use your plan's monthly email verification allowance. Free includes 100. Each deep request uses one verification.

deepboolean · query · optional

When true, include optional detail in deep. Access depends on the endpoint: pooled detail, an included paid-plan profile, or a metered check. Core values stay unchanged.

Run uses the free demo on API 2.0.0. Copied code uses your API key when signed in, or YOUR_API_KEY when signed out.

SDK quickstart
import { parseAPI } from '@parseapi/sdk';

const parse = parseAPI("YOUR_API_KEY");
const result = await parse.email("hello@gmail.com");
console.log(result);

Run on your server with a secret key. Calling from a browser or app?

  "valid": true,
  "free": true,
