Providers

API3 QRNG is built on Airnode RRP, and as a result is provider-agnostic. See below for the providers that are currently available. Each provider has an Airnode address with an extended public key (xpub) and two endpoint IDs.

• airnode: The address that belongs to the Airnode that will be called to get the QRNG data via its endpoints. This is not AirnodeRrpV0 contract address.

• xpub: The extended public key of the Airnode (airnode).

• endpointIdUint256: The Airnode endpoint ID that returns one random number of type uint256.

• endpointIdUint256Array: The Airnode endpoint ID that returns multiple random numbers of type uint256[]. Takes one parameter named size of type uint256 (maximum value: 512).

ANU Quantum Random Numbers

Australian National University is one of the leading research universities in Australia. Visit their website at https://quantumnumbers.anu.edu.au.

ANU Quantum Random Numbers are only available on mainnets. For testnets use Testnet Random Numbers. Quintessence is available on mainnets and a few testnets.
