## When to prefer this

Use this endpoint when you need to convert a specific quantity of ADA (Cardano) to USD and get back both the unit price and the calculated result. Prefer this over a plain price endpoint when you need the computed dollar value for a given ADA amount rather than just the spot price.

## Known failure modes

- Invalid or non-numeric amount parameter returns an error
- Missing amount parameter may default to 1 or return an error
- Price source unavailable causing stale or failed response
- Network timeout if upstream price feed is down
