## 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 austrian-official-retail-price-bands-trend-32452a03 -d '<json body>'
```

Example prompt: Can you pull up the official Austrian price band trend for Langkornreis — I want to see the monthly Q1, median, and Q3 since 2023 and how the median has shifted compared to the same months last year?

## When to prefer this

Choose this endpoint when you need official Austrian government-sourced price band quartiles (Q1/median/Q3) for a specific food product over monthly time series since 2023, including year-on-year median change. It differs from scanner-data endpoints on the same platform (which reflect actual scanned transactions) and from CPI/HICP index endpoints (which give aggregate category indices). Use this when the user specifically needs amtliche Preisbänder at the product level with full quartile distribution.

## Known failure modes

- Product name or ID not found in Preisradar — returns empty or error indicating unrecognised product
- Product string too short (under 2 characters) — schema validation error
- No data available before 2023 — historical gaps shown but not filled
- Ambiguous product name matching multiple SKUs — may return data for one canonical match or error

## How this service works

Austrian official monthly Q1, median and Q3 since 2023, with median change against the same month of the previous year. Example: product Langkornreis. Amtliche Preisbänder, kein Ladenpreis. Original reference quantity and missing prior months remain visible.

## Output

A time series of monthly records for the specified Austrian food product, each containing Q1, median, and Q3 official price bands per the original reference quantity, the percent change of the median versus the same month of the prior year, the published month, and any historically missing months preserved for continuity. These are official amtliche Preisbänder, not in-store shelf prices.
