## When to prefer this

Choose this endpoint when you need a quick, lightweight currency conversion for a specific amount between two currency codes. It is well-suited for agents handling travel budgeting, international invoicing, e-commerce price display, or any workflow where a numeric amount must be expressed in a different currency. Prefer this over a full forex data feed when you only need a single point-in-time conversion rather than historical rates or bulk conversions.

## Known failure modes

- Invalid or unsupported currency code returns an error (e.g. 'XXX' is not a valid ISO 4217 code)
- Missing required base or target query parameter results in a 400 bad request
- Non-numeric amount string may cause a validation error
- Stale or unavailable exchange rate data may result in a service error
- Network timeout or upstream rate-feed outage returns a 5xx error

## How this service works

Convert an amount from one currency to another.

## Output
