## 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 real-estate-listing-market-analysis-4c33956d -d '<json body>'
```

Example prompt: Can you analyze listing ID 48291 and tell me if it's priced below, at, or above market — and show me the closest comps and its price history?

## When to prefer this

Use this endpoint when you already have a specific listing ID and need a structured market assessment including comps and price history — ideal for buyers evaluating whether to make an offer, investors checking margins, or agents benchmarking a seller's asking price against current market data.

## Known failure modes

- Invalid or non-existent listing ID returns an error or empty result
- Insufficient comparable listings in the area may reduce comp count below 10
- Payment failure via x402 prevents call from completing
- Listing data may be stale if the underlying data source hasn't refreshed recently

## How this service works

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 between the listing price and the comparable median, a margin figure, up to 10 comparable listings, and the full recorded price history for the specified listing.
