## 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 reuseful-shop-deal-check-3257f675
```

Example prompt: Is $120 a good deal for a used iPhone 12 in good condition — can you check if that asking price is fair compared to the market?

## When to prefer this

Use this endpoint when you have a specific asking price and want a quick binary or tiered judgment (good/fair/poor deal) rather than a raw price estimate. It is distinct from the price estimate endpoint (which gives a range) and the price history endpoint (which shows trends) — this endpoint is specifically for deal evaluation against a known asking price.

## Known failure modes

- Missing required query parameters 'q' or 'price' returns an error
- Item description too vague to match market data may return low-confidence or no result
- Unusual or niche items with limited market data may yield unreliable verdicts
- Price provided in wrong currency or format may produce incorrect comparisons

## How this service works

Deal check: is this asking price good relative to the market

## Output

Returns a judgment on whether the asking price is good, fair, or poor relative to current market conditions for that second-hand item, likely including context such as how the price compares to typical market values.
