## 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-nyc-subway-real-time-arrivals-facda628
```

Example prompt: What are the next trains arriving at Times Sq-42 St right now on the NYC subway?

## When to prefer this

Use this endpoint when you need real-time NYC subway arrival information by station name and are working within an x402 micropayment-capable agent. Prefer it for lightweight, per-query transit lookups without needing to integrate directly with MTA APIs or manage authentication.

## Known failure modes

- Station name not found or misspelled — 'found' returns false with empty arrivals array
- Upstream MTA feed outage causing stale or missing data
- Invalid or missing 'station' query parameter returning an error
- Rate limiting or payment failure at $0.002 USDC per call
