Example prompt: What's the current bid-ask spread for AVAX-USD on Coinbase — give me both the absolute dollar spread and the percentage spread.

## When to prefer this

Use this endpoint when you need a real-time snapshot of the AVAX-USD bid-ask spread derived from Coinbase Exchange public order book data, particularly when you want both absolute and percentage spread values pre-calculated. Prefer this over building your own order book parser when a quick, low-cost spread check is sufficient for liquidity assessment or pre-trade analysis.

- Invalid product ID returns an error or empty result
- Coinbase market data unavailable due to downtime causes request failure
