help WebPageTest API FAQ

Do I need an API key to run automated tests using the WebPageTest API?

Yes, to interact with the WebPageTest API programmatically, you must register for a free or paid account to receive a unique API key. All REST requests sent to the testing servers must include this key in the URL parameters for authentication.

Who owns and operates the underlying infrastructure for the WebPageTest API?

Catchpoint, a major digital experience monitoring company, acquired the WebPageTest platform in 2021. They utilize a global network of dedicated testing agents and cloud infrastructure, including AWS, to simulate users from various geographic locations.

Can the WebPageTest API return results in JSON format for CI/CD pipelines?

Yes, the API is specifically designed to output structured data in JSON format, making it easily parsable by automation scripts. This allows developers to trigger tests directly from GitHub Actions or Jenkins and automatically fail builds if website loading speeds regress.

Is there a cost associated with using the WebPageTest API for high-volume automated testing?

While WebPageTest offers a limited number of free API runs per day for basic users, high-volume commercial usage requires a paid subscription. Upgrading to a premium tier lifts the daily run limits and provides priority access to the testing queues.
