Historical Backfill
Every resolved prop,
with its closing line.
A one-time download of every player prop we've graded against real box scores — each row carrying the pre-game closing line. It's the CLV/backtest dataset other odds APIs can't produce, because they don't resolve props. $99 once. No subscription.
Get the backfill — $99Why you can't just build this from an odds API
Odds APIs sell you prices. None of them tell you whether the prop hit. To build what's in this file from the-odds-api you would have to: pull historical odds, find the right pre-game snapshot yourself, source box-score stats from a second provider, and write your own grading logic for every market type. We've done all of that — the output is one CSV.
Graded against reality
Every Over/Under settled won/lost/push against the actual box-score stat, with the real value in the row.
Closing line included
The last price at or before first pitch, per outcome — the anchor CLV is measured against. No second call.
Every book, every sport
One row per book per outcome across all 54sports we grade — line-shop and cross-book in the same file.

One row per (event, market, bookmaker, outcome). CSV streams straight to disk; gzips to a fraction of its size.

Plus the full line-movement history — not just the close
The resolved-props file gives you the pre-game closing line. Your pass also unlocks the raw tick history — every odds snapshot we ever recorded, for every outcome, across every book, including period markets. It's the open-to-close line path for the entire archive. No subscription tier can pull this in bulk — Pro and Streaming get it one event at a time; the bulk firehose is part of the backfill pass and Enterprise only.

Coverage:PropLine's archive begins in early April 2026, so exports run from then to the present — the depth grows daily, but it does not extend to earlier seasons. The 2-year lookback is a forward limit on how far back a request may reach, not a guarantee of two years of history. Requests for a window before April 2026 return an empty file.
