## 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 transit-withzero-ai-transit-with-zero-root-endpoint-ab87de56
```

Example prompt: Can you show me the available public transit routes from Amsterdam Centraal to Utrecht using the transit.withzero.ai service?

## When to prefer this

Use this endpoint when building AI agents that need to plan or suggest public transit journeys within Europe, especially when using open-source routing data via Transitous. Prefer this over general mapping APIs when specifically needing European transit schedules and route planning with crypto-native payment support.

## Known failure modes

- Service unavailable (503) if the underlying Transitous API is down
- Empty or minimal JSON response if the root endpoint only serves as an entry point
- Network timeout if transit.withzero.ai is unreachable
- Unknown pricing may result in unexpected payment requirements via x402 protocol

## Output

Returns a JSON object from the root of the transit.withzero.ai service, likely providing entry-point metadata, API structure, or a redirect to the main transit routing functionality powered by Transitous for European public transit.

## Response schema (JSON Schema)

```json
{
 "type": "object"
}
```
