Advisory: We only operate services from the RANDOM.ORG domain. Other sites that claim to be operated by us are impostors. If in doubt, contact us.
Before you run your client, please review our Usage Guidelines. You need an API key to use these 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.
The libraries let clients access the RANDOM.ORG Core API through JSON-RPC. The libraries provide either serialized or unserialized access to both the signed and unsigned methods of the Core API through the RandomOrgClient class. It also provides a convenience class, the RandomOrgCache, for precaching requests.
