Example prompt: What's the current bid-ask spread for INJ-USD on Coinbase — both the absolute dollar amount and the percentage spread?

## When to prefer this

Use this endpoint when you need a quick, real-time bid-ask spread computation for INJ-USD (or another Coinbase USD pair) expressed in both absolute and percentage terms — particularly useful before executing a trade, monitoring market liquidity, or benchmarking slippage costs. Prefer this over raw Coinbase API calls when you want the spread calculation done automatically rather than computing it yourself from raw order book data.

## Known failure modes

- Invalid product ID returns an error (e.g. non-existent or non-USD trading pair)
- Coinbase market data unavailable or delayed during outages
- Market closed or no active order book results in missing bid/ask data
- Payment failure if USDC balance is insufficient for the $0.01 fee
