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.

Declared season scope; individual event-to-season mapping is unverified. 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.

What's in the dataset

Dated snapshot: 125,701,686 depth rows · 497,174,484 total rows · book samples 2026-03-28T17:36:32Z through 2026-10-03T23:59:21Z · artifact vintage 2026-10-03; separate from observation times

✓ Dated snapshot: 125,701,686 depth rows · 497,174,484 total rows · book samples 2026-03-28T17:36:32Z through 2026-10-03T23:59:21Z · artifact vintage 2026-10-03; separate from observation times
✓ Polymarket soccer (MLS, big-5 leagues, UCL, UEL, Libertadores) top-of-book quotes sampled about every 30 s plus per-level L2 depth (up to 20 levels per side, from Jun 16). Quotes and book levels only, no trade prints; not a census. COVERAGE.md derives every capture gap, missing day-file and capture era.
✓ Version-specific observation gaps are documented in the delivered archive; missing observations are not proof a market was closed. Displayed quotes are observations, not proof of executable fills.
