❓ How to use it?

Simple REST API. Here's how it works:

Sign up on Omkar Cloud by visiting this link.
Visit the API Key Page.
Copy your API key.
Make a request:

cURL:

curl -X GET "https://email-verification-api.omkar.cloud/verify?email=happy.to.help%40omkar.cloud" \
  -H "API-Key: YOUR_API_KEY"

Python:

import requests

email = "happy.to.help@omkar.cloud"
api_key = "YOUR_API_KEY"

response = requests.get(
    "https://email-verification-api.omkar.cloud/verify",
    params={"email": email},
    headers={"API-Key": api_key}
)
print(response.json())

JavaScript (Node.js):

import axios from "axios";

const email = "happy.to.help@omkar.cloud";
const apiKey = "YOUR_API_KEY";

const response = await axios.get("https://email-verification-api.omkar.cloud/verify", {
    params: { email },
    headers: { "API-Key": apiKey }
});
console.log(response.data);

Get verification results and use them.

That's it. Email to verification result in milliseconds.

API Reference

Endpoint

GET https://email-verification-api.omkar.cloud/verify

Parameters

email (required, string):
The email address to verify. Must be a valid email format. Example: happy.to.help@omkar.cloud.

Response

Returns verification status and owner details:

{
  "is_valid": true,
  "status": "valid",
  "is_free_email": false,
  "first_name": null,
  "last_name": null,
  "gender": null
}

❓ What data does the API return?

You get:

is_valid — Whether the email address is deliverable (true/false)
status — Verification status (e.g., "valid", "invalid")
is_free_email — Whether the email is from a free provider like Gmail, Yahoo, or Outlook
first_name — Owner's first name (when available)
last_name — Owner's last name (when available)
gender — Owner's gender (when available)

All in structured JSON. Ready to use in your app.

❓ How accurate is the data?

The API performs multi-step verification: syntax check, MX record lookup, and SMTP server ping.

This is the same approach used by industry-leading email verification services. You get accurate, real-time deliverability results.

❓ Can it detect disposable/temporary emails?

Yes. The API identifies disposable email providers (like Guerrilla Mail, Temp Mail, Mailinator) and flags them accordingly.

This helps you block throwaway signups and keep your user base clean.
