Technical details
Endpoint
POSThttps://market.datapackvibe.com/x402/demand-market-uniswap-orderbook-top?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a lightweight, real-time snapshot of the best bid/ask for UNI-USD (or another Coinbase USD market) without requiring a full order book depth feed. Prefer this over full order book endpoints when only the top-of-book spread or reference price is needed.
