The API allows 60 requests in 10 seconds from one address. Above that it answers 429 for 10 seconds with a `Retry-After` header, a `RateLimit-Policy` header and a JSON body that gives the limit. Every API answer carries the same `RateLimit-Policy`. A client should wait the `Retry-After` seconds, or read the files, which have no limit. Every JSON answer carries the version, licence and attribution. CSV and NDJSON answers carry them in response headers. Roads ACT, City and Environment Directorate has not endorsed this site.
