## How to call it through Zero

## When to prefer this

Use this endpoint when a user needs a quick, actionable market value estimate for a specific used vehicle, especially when a sell-vs-hold recommendation or trade-in context is needed. Prefer this over generic car listing searches when the user wants a price appraisal rather than browsing inventory.

## Known failure modes

- Missing required parameters (no VIN and no year/make/model) returns a 422 validation error
- Unrecognized make/model combination returns a 404 with no value data
- Vehicle year out of supported range returns an error indicating data unavailability
