## When to prefer this

Use this endpoint when you need real-time spot price, bid/ask spread, or volume data specifically for the OP-USD pair on Coinbase Exchange. Prefer this over generic crypto price APIs when you need Coinbase-sourced data with bid/ask granularity rather than just a last-traded price aggregated across exchanges.

## Known failure modes

- Invalid product ID returns an error or empty response
- Coinbase Exchange downtime or API unavailability causes request failure
- Network timeout if Coinbase data feed is temporarily delayed
- Unsupported trading pair (non-USD or delisted token) returns no data
