What is Polymarket Scraper?

Polymarket Scraper extracts prediction markets from Polymarket through its public Gamma API: question, outcomes with live prices (the market's implied probability), 24-hour and total volume, liquidity, best bid/ask, last trade, spread, end date and the parent event — one clean row per market. Rank markets by 24h volume, total volume, liquidity, end date or newest, filter by tag (politics, crypto, sports…), expand whole events, or search by text. No API key, no wallet. Schedule it, pipe it into a dashboard or a model, or let an AI agent call it through MCP.

How to use Polymarket Scraper

  1. Pick a Mode: markets (individual markets) or events (every market of each event, with event tags).
  2. Optionally set a Tag such as politics, crypto, sports or economy, and a Sort by (24-hour volume by default).
  3. Or type Search text — bitcoin, election, Fed — to get the markets of matching events.
  4. Set Max markets and click Start. Export JSON, CSV or Excel, or read the dataset through the API.

}

How much does it cost?

Pricing: Polymarket Scraper costs $1 per 1,000 markets (pay per result, platform usage included). The top 100 markets by volume cost about 10 cents.

Use cases

  • Odds tracking — schedule an hourly run and store outcomePrices to chart how probabilities move.
  • Event-driven research — what the market expects for elections, Fed decisions, crypto prices or sports.
  • Trading and arbitrage signals — compare Polymarket prices with sportsbooks, other prediction markets or your own model.
  • News and dashboards — the most-traded questions of the day, ranked by 24-hour volume.

Limits

  • Prices are a snapshot at run time, not a stream; schedule runs for a time series.
  • In markets mode Polymarket returns the parent event without tags, so tags is empty there — use events mode or search when you need tags.
  • Text search returns the markets of the best-matching events, as Polymarket's own search ranks them.

FAQ

Do I need a Polymarket account, wallet or API key? No. The Gamma API is public and read-only.

What does a price of 0.62 mean? Shares of that outcome trade at 62 cents — the market's implied probability of about 62 %.

Is this financial advice? No. It is market data for information purposes only.
