## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability mbta-vehicles-by-route-da8384fd -d '<json body>'
```

Example prompt: Can you show me the live positions and status of all vehicles currently running on the MBTA Red Line?

## When to prefer this

Use this endpoint when you need real-time Boston MBTA vehicle tracking data for a specific route — positions, bearings, and statuses of all active vehicles on that route. Prefer this over general transit APIs when the user is specifically asking about MBTA (Boston) transit and needs live location data rather than schedules or stop information.

## Known failure modes

- Invalid or unrecognized route identifier returns empty results or error
- MBTA API upstream outage causes stale or unavailable data
- Missing required 'route' query parameter results in a bad request error
- Route with no active vehicles returns an empty list

## How this service works

## Output

A JSON array of vehicle objects for the specified MBTA route, each containing the vehicle's current GPS position (latitude/longitude), bearing (direction of travel), and operational status (e.g. in transit, stopped).
