How It Works
Integrate disposable email detection in three simple steps
Get Your API Key
Sign up for free and get instant access to your API credentials. No credit card required.
Make the API Call
Send a simple GET request with the email or domain you want to check.
Get Results
Receive an instant response indicating whether the email is disposable or legitimate.
// Example API Call

headers: { 'Authorization': 'Bearer YOUR_API_KEY' }
})
.then(res => res.json())
.then(data => {
if (data.disposable) {
// Block the signup
console.log('Burner email detected!');
}
});// Example API Call with DNS
fetch('https://burnerbouncer.com/check?input=user@company.com&dns=true', {
headers: { 'Authorization': 'Bearer YOUR_API_KEY' }
})
.then(res => res.json())

Frequently Asked Questions
Why should I block disposable emails?
+
Users create throwaway accounts with burner emails to exploit your free tier, signing up again and again for fresh credits or trial access. Each fake account costs real money in compute, AI tokens, or whatever you give away. They rarely convert. Blocking disposable emails at signup stops the bleed before it starts.
How do disposable emails affect my free trial or credits?
+
Every free tier has a cost. When one person creates 10 accounts with 10 burner emails, you give away 10x the resources for zero revenue. Disposable email detection is the simplest way to enforce one-account-per-user and protect your margins.
What is a disposable email address?
+
A disposable email, also called a burner, throwaway, or temporary email, is an address that works for a few minutes or hours and then vanishes. They are designed to be used once and forgotten, which makes them perfect for dodging registration requirements and abusing free tiers.
How accurate is your detection?
+
We maintain a comprehensive database of over 100,000 known disposable domains, updated daily. Our hierarchical matching algorithm catches subdomains and variations automatically.
Can I upgrade or downgrade my plan?
+
Yes. Upgrades take effect immediately, while downgrades and cancellations apply at the end of your current subscription period.
Can I add my own domains to the blocklist?
+
Yes. On the Burner plan, you can blocklist specific domains that are unique to your industry or that you have identified as problematic. These are checked alongside our main database.
