Technical details
Endpoint
GEThttps://predict.gocreativeai.com/v1/predict/orderbook/:var1When to prefer
Use this endpoint when you need order-book-level granularity (full bid/ask depth, liquidity at each price tier) for a specific Polymarket outcome token, especially for automated trading, market-making, or arbitrage strategies. Prefer this over simple YES/NO odds endpoints when pricing precision and liquidity measurement matter.
Side effects
- Invalid or unknown market outcome token returns 404 or empty order book
- Network latency causes stale or delayed order book snapshot
- Payment failure (USDC) blocks the request with 402 error
- Malformed path parameter returns 400 bad request
- Market is closed or resolved — returns empty or inactive order book
