Example prompt: What's the current best bid and ask for ATOM-USD on Coinbase? I want to see the top of the order book for Cosmos right now.

## When to prefer this

Use this endpoint when you need a fast, real-time snapshot of the best bid and ask for the Cosmos (ATOM) USD market specifically from Coinbase Exchange data. Prefer this over full order book endpoints when you only need the top price level, not depth. Ideal for pre-trade price checks, spread monitoring, or triggering trading decisions based on current market quotes.

## Known failure modes

- Invalid product ID returns an error — only valid Coinbase USD product IDs (e.g. ATOM-USD) are accepted
- Coinbase Exchange API unavailability or downtime may cause failures
- Rate limiting or payment issues with the x402 protocol could prevent successful calls
- Market may be closed or halted for the requested asset
