that has Internet access, including web applications and mobile
apps. You need an API key to use the API.
Before you run your client, please review our Usage Guidelines.
Explains how to use the simplest interface to fetch true
random numbers into your mobile app or web app. This is a good
second chapter to read, even if you want ultimately to write a

Explains how to generate digitally signed random data, such
that you can prove it really came from RANDOM.ORG (authenticity) and that your application has not tampered with it
(integrity). This is useful if you want your
application to implement non-repudiation.
