## When to prefer this

Use this endpoint when you need real-time best bid/ask data specifically for the PEPE-USD pair on Coinbase Exchange. Prefer this over full order book endpoints when you only need the top-of-book quote, not depth. Ideal for quick spread checks, entry/exit timing decisions, or monitoring meme coin pricing without subscribing to a full market data feed.

## Known failure modes

- Invalid product ID returns an error — only valid Coinbase USD product IDs are accepted
- Market temporarily unavailable or exchange downtime may cause failed or stale responses
- Network timeout if Coinbase Exchange data feed is slow
- Thin market conditions may produce unusually wide spreads that appear anomalous
