## 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 italian-house-price-index-by-region-istat-ipab-e1d8dd27
```

Example prompt: What's the latest ISTAT house price index for Milan — how much have prices changed in the last quarter and over the past three years?

## When to prefer this

Use this endpoint when you need official, ISTAT-sourced Italian residential property price index data broken down by region or city, with quarterly and multi-year trend figures. Prefer this over generic real estate listing APIs when you need statistical index benchmarks rather than individual property listings or valuations. Ideal for investment analysis, market research, or regulatory compliance contexts requiring authoritative Italian government data.

## Known failure modes

- Invalid or unrecognised region name returns empty or null region data
- Data may lag by one quarter if ISTAT has not yet published the latest update
- National-level data returned if region param is omitted or left empty
- Service unavailability (Railway.app hosting downtime) returns HTTP 5xx

## How this service works
