PolyMarket

by berlinbra

Read prediction-market prices, probabilities and price history from PolyMarket.

Economic, Alternative & Prediction-Market Data
Summary
What a market thinks will happen, with the history behind the number.

Current price plus the history is the pairing that matters: today's probability means something quite different if it was far lower last week. The tools read markets; placing or settling a position is not part of the set.

What it is

A server over the PolyMarket API for market listings, current prices and historical price and volume data.

What you get
  • The markets available on PolyMarket (list-markets)
  • One market in detail, with category, description and resolution date (get-market-info)
  • Current prices and the probabilities they imply (get-market-prices)
  • Price and volume history over 1d, 7d, 30d or the market's whole life (get-market-history)
  • Rate-limit handling and consistent formatting, so responses arrive usable
Requirements

A PolyMarket API key and a wallet address, passed as KEY and FUNDER. Run with uv from a clone, or installed for Claude Desktop through Smithery.
