## 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-city-to-city-transit-comparison-c3224ff0
```

Example prompt: Can you do a head-to-head comparison of the transit systems in Chicago and Seattle? I'm deciding where to relocate and want to know which city is more navigable without a car.

## When to prefer this

Use this endpoint when a user needs a direct apples-to-apples transit comparison between exactly two cities — ideal for relocation decisions, travel planning, or urban research. Prefer this over single-city transit endpoints when the core question is relative ('which is better') rather than absolute. Choose this over general web search when structured, comparable transit metrics are needed.

## Known failure modes

- City name not recognized or too ambiguous — returns error asking for clarification
- Both city inputs required; missing one returns a validation error
- Very small cities with no formal transit data may return incomplete or unavailable comparison
- Rate limit or payment failure returns 402 or 429 error
