## When to prefer this

Choose this endpoint when you need real-time best bid/ask quotes specifically for AVAX-USD (or another Coinbase USD pair) without subscribing to a full order book feed. Ideal for quick price checks, spread calculation, or triggering trade logic based on top-of-book conditions. Prefer over full order book endpoints when only the best level is needed.

## Known failure modes

- Invalid product ID returns an error or empty response
- Market closed or low liquidity may result in missing bid or ask levels
- Payment failure (insufficient USDC) blocks the request
- Network timeout if exchange feed is delayed
- Stale data if order book feed is momentarily disconnected
