How this service works
Live order book for a Coinbase spot pair: best bid/ask, mid price, spread in bps, USD liquidity within 1% of mid on each side, and the top bid/ask levels (up to 50). Useful for slippage and execution checks.
Output
Returns a structured snapshot of the live Coinbase order book for the requested pair, including: best bid price and size, best ask price and size, mid price, spread in basis points, total USD liquidity within 1% of mid on both the bid and ask sides, and the top N bid/ask price levels (up to 50) with sizes.
Example use cases
Pre-trade slippage check for large ETH buy
“Before I place a large ETH buy, can you pull the ETH-USD order book with 50 levels deep and tell me how much USD liquidity is within 1% of mid on the ask side so I can estimate my slippage?”
Real-time spread monitoring for SOL-USD
“What's the current bid-ask spread in basis points for SOL-USD on Coinbase? Show me the top 10 levels on each side too.”
Cross-pair liquidity comparison for ETH-BTC
“I'm deciding whether to trade ETH directly for BTC or route through USD — can you check the ETH-BTC order book with 20 levels and show me the mid price, spread, and liquidity within 1% of mid?”
Technical details
Endpoint
POSThttps://dt0ur.online/api/market/orderbook?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time Coinbase-specific order book data for execution quality checks, slippage estimation, or market microstructure analysis. Prefer this over generic price feeds when you need depth-of-book liquidity data (not just last traded price), spread in basis points, or USD liquidity within a price band — especially for pre-trade analysis on Coinbase spot pairs.
Side effects
- Invalid product ID returns an error — must use a valid Coinbase product format like BTC-USD, ETH-USD, SOL-USD, ETH-BTC
- Depth out of range (less than 1 or greater than 50) will be rejected
- Network or exchange connectivity issues may return stale or unavailable data
- Payment failure for the $0.01 USDC per call fee results in 402 error
