Questions

Where can I download NHL historical odds as a CSV?

Right here. A sample week, September 15 to 21, 2026, downloads free with no key. Recent data and the full NHL history back to June 4, 2026 are a subscription. Every file also comes as JSON or Parquet with the same rows and columns.

Does this include NHL opening and closing lines?

Closing lines, yes: each book's last price before the game started. For the open, you get the earliest price we captured at that line, which is not always the market's first posted line, and the file labels it that way.

How far back does the NHL data go?

To June 4, 2026. Our coverage starts on June 4, 2026 across every sport, so this is not a multi-season archive. It grows with every NHL game we scan.
