Get the live order book snapshot for a Polymarket outcome token

Price: 1 credit

💡 AI Hint: Get the current order book (market depth) snapshot for one Polymarket outcome token, identified by its clob token id (obtained from a market’s outcomes via the markets endpoint). Returns the full ladder of resting bids and asks (each a price/size level), the derived best bid, best ask, spread and midpoint, the last trade price, tick size, minimum order size, and the snapshot timestamp. This is a point-in-time snapshot of resting liquidity, not a price history.

⚠️ Common errors: 412: Order book not found (token id is unknown or the market has no live order book)
