Frequently Asked Questions

Do I need to be a developer to implement this API?

Our API is rather easy to implement, but some basic programming knowledge is helpful. If you can make HTTPS requests or use tools like Postman, you can test and implement our service. Many no-code platforms also support API integrations.

What programming languages does your API support?

You can use ANY programming language, as long as you can make requests to our HTTPS endpoints. As long as you can use fetch/curl/something, you should be able to use the API.

What should I check for in the response?

The most important value in the response is "block". It is set to "true" if the domain or email is either invalid, or disposable. If Block it's true, it should be safe to deny the user to register/etc.

How do I authenticate API requests?

You need an account on Rapid, which is an API marketplace. You can see more under API and authentication.

Do you offer free trial requests or a free tier?

Yes. Our free tier allows you to do up to 1000 requests per month, free forever.

Do you only check domains, or full email addresses?

The API supports checking full email addresses, so that we can block known disposable or abusive addresses. However, for data protection (like GDPR) reasons, you can submit just the domain name also.

How do I upgrade or downgrade my subscription plan?

You can easily do this in your Rapid dashboard.

What's the risk score in the response?

The risk score is an automatically calculated score (0-100), depending on multiple inputs and values. We use many inputs (domain owner, IP addresses, history, threat feeds, etc) to automatically block disposable or suspicious e-mails and domains.

How accurate is your disposable email detection?

We use many automatic and manual processes, to make sure we're among the top performers in blocking disposable temp mail. Our heuristic systems often automatically block new disposable domains within minutes, without human intervention.

What is temp mail?

We go through what is temp mail on our website.

How do I report false positives or missed disposable emails?
