Source Code (Release 2)

Official Libraries

The official libraries are supported by the RANDOM.ORG team. We do our best to make sure they are feature-complete and well tested.

Java/Android

GitHub: https://github.com/RandomOrg/JSON-RPC-Java
Dependencies: Requires the gson lib for normal operation, and the junit lib to run tests.
Added: 2013-03-05
Updated: 2021-01-29
API Releases Supported: R1, R2, R3
License: MIT License

This is a Java implementation of the RANDOM.ORG JSON-RPC API (up to and including R3). It provides either serialized or unserialized access to both the signed and unsigned methods of the API through the RandomOrgClient class. It also provides a convenience class through the RandomOrgClient class, the RandomOrgCache, for precaching requests. In the context of this module, a serialized client is one for which the sequence of requests matches the sequence of responses.

Python
