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.

Season scope not verified Observed partial coverage

A competition season has not been verified for this archive. This is not a complete-season archive.

UTC timestamps retain their recorded precision; dates alone identify UTC days. Vintage, observation and sports event times are separate. Capture time does not establish exchange quote freshness.

Sports event starts: start unknown → end unknown. Event dates are not inferred from these quote capture windows.

Why the capture contract matters

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.

✓ L2 depth ladders (top 20 levels per side) + top-of-book snapshots for 47 of 104 World Cup 2026 match markets, across 141 outcome tokens.
✓ 20,796,142 depth rows with per-level price/size, plus 954,838 top-of-book rows, in per-match Parquet files with a manifest.
✓ Coverage is partial and disclosed match-by-match: Jun 11–19, the final group day, the round of 32, and three round-of-16 matches are absent; the Jun 22 source is corrupted.
✓ This is historical sampled book state, not a trade tape or outcome dataset. Free sample: one disclosed group-match slice.
