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).
