ANU Quantum Numbers (AQN) API is one of 6 APIs that [Australian National University](https://apis.io/providers/anu/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. This API exposes 1 JSON Schema definition. Tagged areas include Quantum, Random Numbers, Research, and JSON. The published artifact set on APIs.io includes API documentation, an OpenAPI specification, authentication docs, and 1 JSON Schema.

ANU's current quantum random number service, operated by the ANU Quantum Optics group on ANU's own AWS account under ANU's own domain. Returns arrays of uint8, uint16, hex8 or hex16 values, length 1-1024, with a block-size parameter for the hexadecimal types. A free API key is issued self-serve and sent as the x-api-key header; the gateway returns 403 {"message":"Forbidden"} without one. ANU publishes no OpenAPI — the specification pointed at below is derived by API Evangelist from ANU's own documented parameter table and call form.
