## 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-stop-live-predictions-1c223f85 -d '<json body>'
```

Example prompt: What are the next train arrivals and departures at South Station right now? The MBTA stop ID is place-sstat.

## When to prefer this

Use this endpoint when you need real-time or near-real-time arrival and departure predictions for a specific Boston MBTA stop and have the MBTA stop ID (e.g., place-sstat for South Station). Prefer this over static schedule lookups when live transit data is required.

## Known failure modes

- Invalid or unknown stop ID returns an error or empty predictions array
- Stop with no upcoming service returns empty predictions
- MBTA API outage may result in stale or missing data
- Missing stop parameter returns a bad request error
