## When to prefer this

Use this endpoint when you need real-time MBTA service alert data for a specific Boston transit route — ideal for commuter apps, travel planning agents, or any workflow that needs to check whether a particular MBTA line is running normally before routing a user.

## Known failure modes

- Missing or invalid route parameter returns an error or empty result
- Route name typo (e.g. 'red' vs 'Red') may return no results if case-sensitive
- No alerts returns an empty array — does not mean the API failed
- Network timeout or service unavailability returns a non-200 HTTP status
- Unknown route identifiers (e.g. bus route numbers) may not be supported
