## 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 tfl-london-underground-live-status-9f96676f -d '<json body>'
```

Example prompt: Can you check the current live status of all London Underground lines and let me know if any are delayed or suspended?

## When to prefer this

Use this endpoint when you need a complete snapshot of all London Underground line statuses simultaneously, rather than querying individual lines. Ideal for monitoring dashboards, travel planning apps, or any agent needing to alert users about Tube disruptions across the whole network.

## Known failure modes

- TfL API upstream unavailability returns an error or empty response
- Stale data if TfL feed is temporarily frozen
- Payment failure (402) if USDC balance is insufficient
- Malformed JSON if provider is experiencing issues
