## 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 uk-ireland-used-car-import-agent-single-listing-valuation-a9be542f
```

Example prompt: Can you check if carzone listing 4577902 is good value — is it below, at, or above market price, and what do comparable listings look like?

## When to prefer this

Use this endpoint when you already have a specific listing ID from a supported Irish platform (carzone, joeduffy, windsor, frankkeane, spirit, denismahony) and want a detailed valuation verdict, comparable listings, and price history for that one car. Prefer this over search/browse endpoints when the listing is already identified and you need a buy/pass decision with market context.

## Known failure modes

- Invalid or unknown listing_id returns an error or empty result
- Unsupported source_platform value returns a validation error
- Listing has been removed from the platform and returns no data
- Insufficient comparable listings exist to compute a reliable median
- Network timeout or railway.app service unavailability

## How this service works

Is this specific Irish car listing good value? - Use to assess one listing you already have an id for: verdict (below/at/above market), percentage vs the comparable median, margin, up to 10 closest comparable listings and the listing's recorded price history.

## Output

Returns a market verdict (below/at/above market), the percentage difference vs the comparable median price, the margin in currency, up to 10 closest comparable listings with their details, and the full recorded price history for the specified listing.
