Sold by: Quantum numbers by ANU
Need independent, reliable and trusted random numbers for your software, experiments or simulations. We provide quantum numbers that are guaranteed random by the laws of physics.
3
Overview
True randomness generated in a physics laboratory at the Australian National University. We use lasers and high speed detectors to continuously measure quantum vacuum fluctuations which provide an endless source of reliable and trusted entropy. This high quality entropy source can be accessed through an API request.
Each API request can deliver up to 1024 numbers in decimal or hexadecimal format. Each random number is served to only one request and never reused.
- Subscription allows unlimited requests and you are only charged for what you use. More information is available at https://quantumnumbers.anu.edu.au .
- For custom pricing or an enterprise contract, please contact qrng@anu.edu.au .
Highlights
- Reliable source of randomness.
- Free tier available.
- Simple and easy to use API. No knowledge of quantum physics required.

Dimensions summary
This listing offers one pricing dimension: the Unlimited plan, billed by usage on requests. You subscribe to make API calls that return quantum-generated random numbers. There are no separate tiers or instance sizes to choose from on Marketplace. You pay based on your request activity under this single plan. The service runs through AWS cloud architecture, which handles distribution and payment. Requests can reach up to 100 per second under the paid plan. If you need higher rates, you contact the vendor to discuss your application.
Top-of-mind questions for buyers
One request is a single API call to the service. Each call returns a batch of quantum-generated random numbers measured from vacuum fluctuations. Numbers are never reused or served to more than one request. The paid plan accepts up to 100 requests per second.
The paid plan meters requests and accepts up to 100 per second. If your application needs higher rates, you contact the vendor to discuss your requirements. The underlying setup generates numbers at 5.7 Gbits/s, so higher distribution rates can be arranged directly with them.
Yes. The paid version of the service requires an AWS account. The API runs through AWS cloud architecture, which handles distribution of random numbers and processes payment. You add the service to your application by making an API call using your key.

I've been experimenting with this API for years now. It works flawlessly; very reliable. Perfect uptime. Really amazing to have access to verifiably non-deterministic numbers.

Works perfectly. Using it with an IOS app to generate a random number. Just be sure to follow the API documentation. Thanks!

I am, presumably like the other reviewer, also unable to get this product to work. The free limited version works without issue but the paid subscription key just says INACTIVE and refuses to respond.
It may be a parameter failure as I note they give a Customer ID which is not on the free version but the documentation does not describe how to use it.
I have been unable to get a response from the vendor via email and phone (it is a University and Christmas)
