## When to prefer this

Use this endpoint when you need to surface real used-car listings from CarsDirect.com for a specific US location, optionally narrowed by make and model. Prefer this over generic web search when you need structured vehicle data (price, mileage, condition, colors, dealer distance) in a machine-readable format ready for comparison or display.

## Known failure modes

- Invalid or non-existent US ZIP code returns empty results or an error
- Model slug provided without a make slug may return no results or an error
- Page number out of range (>10) may return empty results
- Residential proxy failure may result in a timeout or 5xx error
- Make/model slugs must be lowercase and hyphenated (e.g. f-150, not F150)
