Polymarket L2 archive — FREE evaluation sample
================================================

This is a real, complete slice of the paid archive (not a synthetic or truncated demo): one
full crypto up/down 5-minute market — the busiest one of its kind (by book_events row count) on
the sample date below — with all three streams for BOTH outcome tokens (up + down) across that
market's entire lifecycle, open through resolution.

Files (Hive/Parquet, same column schema as the paid archive — see /archive/manifest.json for the
exact schema and the full list of available dates):

  book_events.parquet   423840 rows, 6699934 bytes  — full L2: snapshots + price_change deltas + trades + status markers
  trades.parquet        3000 rows, 48737 bytes  — taker tape only
  l1_quotes.parquet     64838 rows, 707142 bytes  — derived top-of-book bid/ask

This sample is regenerated daily from a real recent day, not a fixed historical snapshot. The
paid archive covers the FULL Polymarket universe (crypto up/down + sports + politics markets) for
every date listed in /archive/manifest.json. Auth: an X-API-Key header; the manifest explains how
to request a key.
