## 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 transitpulse-airport-transit-guide-3cd0c1f9
```

Example prompt: Can you check if it's feasible to take public transit from downtown Chicago to O'Hare Airport tomorrow morning, and give me the best route and how long it'll take?

## When to prefer this

Choose this endpoint when a user needs to reach an airport specifically by public transit and wants a feasibility check plus best-route recommendation. Prefer over general trip-planning endpoints when the destination is explicitly an airport and the user needs airport-specific timing guidance (e.g. accounting for check-in windows).

## Known failure modes

- Airport not found or not served by public transit — returns no route available
- Origin location unrecognized — returns location lookup failure
- No transit service available at the requested time — returns service unavailability
- Transit data unavailable for the region — returns coverage error
- Payment of $0.08 USDC not completed — returns 402 Payment Required
