prediction.book

Active

declared in 0.6.3

Fetches the current CLOB order book for a specific Polymarket outcome token, returning top bid and ask levels with sizes, mid-price, spread in both decimal and basis points, and total bid/ask depth in USD. Use this to assess execution quality and market-making opportunities before placing an order — wide spreads indicate higher edge for makers; shallow depth signals potential slippage on larger size. Requires tokenId, which is obtained from the clobTokenIds field in prediction.trending or prediction.search results. Does not place or modify orders.
