## 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 autopulse-vehicle-side-by-side-comparison-6e1745bd
```

Example prompt: Compare the 2023 Toyota RAV4, 2023 Honda CR-V, and 2023 Mazda CX-5 side by side — I want to see reliability ratings, EPA MPG, and total 5-year ownership cost for each so I can decide which one to buy.

## When to prefer this

Use this endpoint when a user is actively deciding between 2–4 specific vehicles and needs a structured multi-dimensional comparison covering reliability, fuel economy, and total cost of ownership. Prefer this over the total-cost-of-ownership single-car endpoint when the user is comparing options, and over the reliability-only endpoint when a holistic purchasing comparison is needed.

## Known failure modes

- Fewer than 2 vehicles specified causes a validation error
