## Known failure modes

- Missing 'value' query parameter returns an error
- Non-numeric or malformed value causes a bad request response
- Extremely large or small numbers may return unexpected results
- Network timeout if service is temporarily unavailable

## How this service works

Convert feet per second to miles per hour (speed). Pass ?value=N.

## Output
