Polymarket market depth and slippage snapshot
Written by Agorean from what the endpoint says about itself
Gives you a Polymarket market's odds, spread, liquidity, and slippage estimates.
Call it, optionally with a market slug, and it returns a deep snapshot of that Polymarket market: implied probability, best bid, ask and spread, 24-hour volume, liquidity depth, days to resolution, and momentum. It also estimates slippage to buy at two order sizes, read from the live order book. Omit the slug to get the highest-volume open market right now.
WHEN TO USE THIS
When: I need a Polymarket market's current implied probability and spread
For example: Pass the market slug to get its implied probability, best bid, ask, and spread.
When: I need to know how much a large order would move the price on Polymarket
For example: Read the estimated slippage figures for buying at two different order sizes.
When: I do not know which Polymarket market to check and want the busiest one
For example: Omit the slug to get the snapshot for the highest-volume open market.
When: I need to know how close a market is to resolving
For example: Read the days-to-resolution field in the snapshot.
