How this service works
Arbitrum 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 (ask minus bid in USD), and percentage bid-ask spread for the specified Coinbase USD trading pair (default ARB-USD). Data is sourced from Coinbase Exchange public market feed and is not investment advice.
Example use cases
Pre-trade liquidity check for ARB

Algorithmic spread monitoring alert
“I'm running a bot that trades ARB-USD — can you pull the latest bid-ask spread percentage for ARB-USD so I can decide if it's within my 0.5% threshold?”
Comparing market conditions over time
“Can you grab the current absolute and percentage bid-ask spread for ARB-USD? I'm logging it every hour to track how market conditions change throughout the day.”

- Network timeout if Coinbase data feed is slow
- Passing a non-USD pair (e.g. ARB-BTC) may return an error or unsupported pair message
