Example prompt: How fast does a Toyota Corolla lose value in Ireland — can you show me the median price by year and how much it drops per 10,000 km?

## When to prefer this

Use this endpoint when you need to understand how a specific car model loses value over time in Ireland — particularly when advising on which model year to buy, assessing whether a high-mileage car is priced fairly, or comparing EV vs ICE depreciation curves. Prefer this over a general valuation endpoint when the user's question is about rate of value loss rather than the current price of a specific listing.

## Known failure modes

- 404 returned when fewer than 5 listings exist for the requested make/model (or make/model/fuel_type combination)
- Missing required 'make' or 'model' query parameters result in a validation error
- Misspelled or unrecognized make/model may return no data or 404
- Very niche or rare vehicles may consistently return 404 due to thin market data

## How this service works

How fast a car model loses value in Ireland - Use to estimate depreciation: median price by model year with year-on-year change, plus price change per 10,000 km. Needs at least 5 listings; otherwise returns 404 and you are not charged.

## Output

Returns a breakdown of median prices for each model year of the requested make and model in the Irish used car market, including the year-on-year percentage or absolute price change and the price change per 10,000 km driven. Requires at least 5 active listings to compute; returns 404 if there is insufficient data.
