# QRNG@ANU Legacy JSON API

**Canonical:** https://apis.io/apis/anu/qrng-legacy/  
**Provider:** Australian National University — https://apis.io/providers/anu/

QRNG@ANU Legacy JSON 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. Tagged areas include Quantum, Random Numbers, Deprecated, and JSON. The published artifact set on APIs.io includes API documentation and an OpenAPI specification.

The original ANU quantum random number endpoint, served from ANU's own web host. No authentication, and throttled to one request per minute. ANU has published a deprecation notice on the documentation page — "The old service will be scaled back and eventually retired" — but names no sunset date and emits no Deprecation or Sunset header. The throttle is signalled with HTTP 200 and a plain-text sentence rather than a 429, so clients must branch on Content-Type, not status code.
