## How to call it through Zero

```sh
zero fetch --capability carfax-used-car-listings-search-49e4f9cf
```

Example prompt: Can you search CARFAX for used SUVs near ZIP 10001 and show me the first page of results, including price, mileage, and history flags like no accidents or one owner?

## When to prefer this

Use this endpoint when you need structured used-car listing data from CARFAX — including vehicle history badges, dealer details, and photos — filtered by body style or price ceiling and optionally geo-located by US ZIP code. Prefer it over generic web search when you need machine-readable vehicle attributes (VIN, MPG, drivetrain) in bulk across 24 results per page.

## Known failure modes

- Invalid or unsupported bodyType value returns empty results or error
- maxPrice value not in the supported discrete set may return no results
- ZIP code not recognized or outside the US returns no nearby listings
- Page number exceeding 50 or total pages returns empty result set
- Stealth proxy blocked or rate-limited by carfax.com — service may return error or empty response
- Both bodyType and maxPrice omitted may return a default or error response

## How this service works

CARFAX used-car listings by body style or price ceiling (optionally near a US ZIP): total matches and 24 cars per page with VIN, year, make, model, trim, mileage, price, value badge, history flags (one owner, no accidents, service history), colour, drivetrain, engine, fuel, MPG, dealer, rating, location, phone, photo and link. From carfax.com via a stealth proxy.

## Output

Returns total match count and up to 24 used-car listings per page, each including VIN, year, make, model, trim, mileage, asking price, value badge, history flags (one owner, no accidents, service history), exterior colour, drivetrain, engine spec, fuel type, MPG, dealer name, rating, location, phone number, photo URL, and a link to the CARFAX listing page.
