Open data

Open data and API

Each published day is released as JSON and CSV under CC BY 4.0: openly licensed derived fields only, with the column list in each file's header. No stock or market series, no descriptions and no Google data.

GET /data/index.json

GET /data/{YYYY-MM-DD}.json · .csv

The Ripple Map files under v2/ (lines, stops, the day line) are public so the map works, but they are not open-licensed as a whole: each stop lists its own sources and licences, and some carry third-party signals. Paid work (reports, briefs, Radar) uses Wikimedia-derived measurements only; channels tagged unofficial or unlicensed on the licences table never enter it. The hash-chained ledger lets anyone check that past lines were not rewritten.
