Per-operator JSON files — UK DNOs
One self-contained file per distribution network operator, plus an index with an MPAN lookup. Every file is plain JSON over HTTPS, UTF-8 without a byte-order mark, no key and no sign-up.
This is a directory listing. The documentation — schema, examples, licence and how to cite — is on the developers page.
