Technical details
Endpoint
POSThttps://market.datapackvibe.com/x402/demand-market-cardano-orderbook-top?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a real-time, point-in-time snapshot of the best bid and ask for Cardano (ADA-USD) specifically from Coinbase Exchange. Prefer this over full order book endpoints when you only need the top-of-book quote, not full depth. Ideal for trading bots, price alerting, spread monitoring, and portfolio mark-to-market workflows where low latency and Coinbase-sourced data is required.
Side effects
- Invalid product ID returns an error — only valid Coinbase USD product IDs (default: ADA-USD) are accepted
- Coinbase Exchange API downtime or rate limiting may cause failed responses
- Stale or delayed data during periods of extreme market volatility
- Network timeout if the upstream Coinbase feed is unavailable
