Polymarket Markets Scraper — Prices, Liquidity & Order Books

Live Polymarket market data as clean JSON: questions, outcome prices, 24h volume, liquidity, end dates, neg-risk flags, and — uniquely — full CLOB order book snapshots with best bid/ask and dollar depth per outcome.

Why this one

Token IDs parsed correctly — Polymarket's gamma API returns clobTokenIds as a JSON string; naive scrapers double-encode it and hand you garbage. This actor parses it properly so every record is API-ready.
Order book depth — not just the midpoint: best bid, best ask, spread, and how many dollars are actually sitting at the touch. Built by a team that runs live trading systems on this exchange.
Real filters — 24h volume, liquidity, text search, sort by volume/liquidity/end date.

Output example

{
  "question": "Will the Thunder win the 2026 NBA Finals?",
  "conditionId": "0x6a3c...",
  "slug": "thunder-2026-nba-finals",
  "endDate": "2026-06-22T00:00:00Z",
  "volume24hr": 1843210.5,
  "liquidity": 412000.2,
  "outcomes": ["Yes", "No"],
  "outcomePrices": [0.62, 0.38],
  "clobTokenIds": ["7131...", "2384..."],
  "negRisk": false,

  ]
}
