Common questions on Clearout APIs, integrations, and developer setup

Clearout API enables developers and website administrators to integrate email verification and email finder capabilities directly into their existing systems, applications, and workflows. The API allows you to verify or find email addresses programmatically without using the web interface.

What is the Clearout API?

The Clearout API allows developers to integrate email verification and email finding into their applications and workflows.

How do I generate an API key?

Go to Menu → Developer → API → Create API Token, name it, and create your token.

What does API response data include?

• Email status

• Safe-to-send status

• Status reason

• Disposable detection

• Role-based detection

• MX & SMTP details

• Timestamp of verification

Why am I getting “Unknown” results?

There can be multiple reasons for an email to end up as an unknown result, including:

• Greylisting

• Server timeout

• Temporary mail server issues

Unknown results do not consume credits.

Why did I hit API rate limits?

API rate limits are determined by the plan associated with your Clearout account. Each plan includes a specific Requests Per Minute (RPM) limit to ensure a fair usage policy across all users.

You can check your current limits under Plans in your Clearout dashboard.

If your application exceeds the allowed RPM, API requests will be responded with a HTTP 429 response code.

To increase your API rate limits, you can:

• Upgrade to a higher plan with increased RPM limits

• Purchase add-ons that provide additional API capacity

If you require higher limits for your use case, please contact Clearout Support via chat or email at [e-mail] for assistance.Response time
