## 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 irish-used-car-market-data-prices-by-county-57f30313
```

Example prompt: Which Irish counties have the cheapest used Toyota Corollas right now, and how do they compare to the national median price?

## When to prefer this

Use this endpoint when you need a geographic breakdown of Irish used-car prices by county — particularly for identifying regional arbitrage opportunities or comparing where a specific make/model is cheapest. Prefer this over the national market overview endpoint when county-level granularity matters. Not suitable for valuing a specific listing or calculating VRT/import costs.

## Known failure modes

- Model filter used without make filter — may return no results or unexpected data
- Small counties with few listings produce statistically unreliable comparisons
- Unrecognised make or model strings return empty results
- Network or payment (x402) failure if USDC balance is insufficient

## How this service works

Used-car prices by Irish county - Use to see where a model (or make, or all cars) is cheapest or dearest across Irish counties, relative to the national median. Small counties may have few listings.

## Output

Returns a list of Irish counties, each with aggregated used-car price metrics (median, mean, etc.) and a comparison to the national median, optionally filtered by make and/or model. Counties with few listings are flagged as having limited data.
