Technical details
Endpoint
POSThttps://market.datapackvibe.com/x402/demand-market-hedera-orderbook-top?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need the best bid and ask levels for HBAR-USD (Hedera) from Coinbase Exchange in real time. It is ideal for trading agents that need price reference data, spread analysis, or market condition checks for Hedera without pulling the full order book depth. Prefer this over full order book endpoints when only the top price levels are needed, minimizing cost and latency.
Side effects
- Invalid product ID returns an error — only Coinbase-listed USD product IDs are valid (default HBAR-USD)
- Market may be closed or illiquid, resulting in empty or stale top-of-book data
- Payment failure or insufficient USDC balance causes the request to be rejected before execution
- Network or upstream Coinbase API outage may result in a timeout or 5xx error
