Artifact vintage: the product page and shipped documentation state the exact coverage, row counts and known limitations. A purchase delivers the advertised frozen artifact; no future refresh is promised unless the checkout terms explicitly say so.
Venue APIs expose useful live books, trades and price history, but they do not serve the same historical snapshot and game-context archive packaged here. Data that was not recorded during the live window cannot be recreated from a current-book endpoint later. The exact fields, cadence, venue coverage and limitations vary by product, so this page and the shipped documentation state the contract explicitly instead of calling every file complete or tick-level.
Dated snapshot: 26,269,229 depth rows · 1,061,149 trade prints · 27,330,378 total rows · 2026-05-15 through 2026-09-12
Align NFL game, spread and total ladders with your own play-by-play feed to measure how displayed depth reprices through scoring drives at ~43 s cadence.
Pair sampled depth with deduplicated NFL prints (taker side, capture-time game state) to study fills against displayed liquidity instead of quotes alone.
We publish real sample rows — not a marketing mockup. Load them in DuckDB, inspect the schema and coverage contract, then decide.
