## 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 saylor-innovations-transit-berlin-vbb-real-time-departures-9405ca46
```

Example prompt: What are the next departures from Alexanderplatz right now — U-Bahn, S-Bahn, tram, whatever is leaving soon?

## When to prefer this

Choose this endpoint when you need real-time or near-real-time departure information specifically for Berlin VBB stops (U-Bahn, S-Bahn, tram, bus). It is ideal for navigation agents, transit dashboards, or any workflow requiring live Berlin public transport data. Prefer it over generic transit APIs when the user's query is specifically about Berlin or Brandenburg stations by name.

## Known failure modes

- Stop name not recognized — 'found' returns false with empty arrivals array
- Ambiguous stop name matching multiple stations — may return results for unexpected stop
- VBB data feed unavailable — upstream timeout or empty response
- Missing required 'stop' query parameter — request rejected
- Stop exists but no upcoming departures in the near-term window — empty arrivals array
