What you get

  • Plain files over HTTPS

    Each series for each place as a small JSON or CSV file, plus every dataset as one CSV or Parquet file. No key or signup.

  • Versions you can cite

    Every update gets a version id, and a pinned URL always returns the same data. The first version of each month is kept for good, so results stay reproducible.

  • Checked before publishing

    Each update is validated against its contract. If a check fails, the last good version stays live.

  • Licenses up front

    Every dataset names its source, its license, the exact credit line and whether commercial use is allowed.
