How this service works
Stellar Bid-ask spread check: Calculate the latest absolute and percentage bid-ask spread. Coinbase Exchange public USD market data; not investment advice.
Output
Returns the latest bid price, ask price, absolute bid-ask spread (in USD), and percentage bid-ask spread for the requested Coinbase USD trading pair (defaulting to XLM-USD). Data is sourced from Coinbase Exchange public market feeds and is for informational purposes only.
Example use cases
Pre-trade liquidity check for XLM
“Before I place a large Stellar buy, what's the current bid-ask spread on XLM-USD? I want the absolute and percentage spread so I can gauge slippage.”
Automated spread monitoring alert
“Check the XLM-USD bid-ask spread right now and tell me if the percentage spread is wider than usual — I'm trying to track liquidity conditions for Stellar.”
Multi-asset spread comparison
“Can you pull the bid-ask spread for XLM-USD and tell me how tight the market is compared to what I'd expect? Give me both the raw spread and the percentage.”

Choose this endpoint when you need a quick, real-time bid-ask spread calculation for a Coinbase USD market pair — especially Stellar (XLM-USD) — and want both absolute and percentage values computed for you without having to manually subtract bid from ask. It is ideal for agents performing pre-trade liquidity checks, spread monitoring, or market condition analysis on Coinbase-listed assets.
Side effects

- Coinbase API downtime may result in stale or unavailable data
- Extremely illiquid pairs may return zero or null bid/ask values
- Network or payment processing failures may prevent the $0.01 USDC charge from completing
