Polymarket

Polymarket is a leading prediction market platform. The Polymarket node provides market discovery, orderbook data, pricing, and trade history.

Prerequisites

No credential required. All operations use Polymarket's public APIs.

Operations

Operation	Description	Key inputs
getMarkets	List prediction markets	searchQuery, sortBy, limit
getEvents	List prediction events	searchQuery, limit
getMarketBySlug	Get a market by its URL slug	marketSlug
getOrderBook	Get orderbook for a token	tokenId
getPrice	Get current price for a token	tokenId
getMidpoint	Get midpoint price for a token	tokenId
getPriceHistory	Get historical price data	tokenId, interval
getActiveMarkets	List currently active markets	limit

Configuration

Field	Type	Required	Description
tokenId	string	For price/book ops	Polymarket token ID
marketSlug	string	For getMarketBySlug	Market URL slug
searchQuery	string	No	Search keyword (max 200 chars)
sortBy	string	No	Sort: Volume 24h, Volume 1w, Volume 1m, Liquidity, Start Date, or End Date
sortType	string	No	Uses descending order for market search
side	string	No	Order side: `buy` or `sell`
interval	string	No	Price history interval: `1d`, `1w`, `1m`, `3m`, `6m`, `1y`, or `all`
limit	number	No	Results limit (default: 20, max: 100)

Price history uses a fixed 60-minute fidelity. Choose the interval in the node; there is no separate fidelity field in the UI.

Output

All operations return the standard envelope:

{
  "success": true,
  "operation": "getPrice",
  "data": { /* raw Polymarket response */ }
}

Reference fields downstream with the response name (default polymarketResponse), for example {polymarketResponse.data.price} for getPrice or {polymarketResponse.data[0].question} for getMarkets. The upstream Polymarket payload is always under .data.
