## 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-boston-real-time-route-vehicle-positions-4e17fa1d -d '<json body>'
```

Example prompt: Where are all the Red Line trains right now? I want their current coordinates, bearing, and status.

## When to prefer this

Use this endpoint when you need live, real-time positions of MBTA Boston transit vehicles on a specific named route (subway lines like Red, Green-B, or bus routes like 1). Prefer this over static schedule data when you need current locations, not planned stops.

## Known failure modes

- Invalid or unknown route ID returns empty results or error
- Route with no currently active vehicles returns empty array
- MBTA API upstream outage may return stale or no data
- Missing or malformed ?q= parameter causes bad request error

## How this service works

Boston (MBTA) real-time vehicle positions for a route — current status, coordinates, bearing and direction. Param q = route id (e.g. Red, Green-B, 1). Query: ?q= Returns JSON.

## Output

A JSON array of active vehicles on the specified MBTA route, each with real-time coordinates (latitude/longitude), bearing (degrees), direction of travel, and current status (e.g. in transit, stopped).
