## When to prefer this

Choose this endpoint when you need a quick, real-time snapshot of the NEAR-USD bid-ask spread derived from Coinbase Exchange order book data. It is ideal for pre-trade cost estimation, liquidity monitoring, or logging spread history for NEAR specifically. Prefer it over generic market data APIs when you need both absolute and percentage spread in a single call without building the computation yourself.

## Known failure modes

- Invalid product ID returns an error — only valid Coinbase USD pairs are accepted
- Coinbase Exchange API downtime may cause data unavailability
- Stale or missing order book data can result in null or unreliable spread values
- Rate limiting or payment failure ($0.01 USDC) may block the request
