# Austrian Food HICP vs National CPI Comparison

> Austrian Food HICP vs National CPI Comparison is a paid API for AI agents from teuerung.halowerk.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-22).

Returns Austrian food HICP and national CPI annual rates side by side for a given COICOP category, showing each published period and the percentage-point difference where both series overlap.

## 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-food-hicp-vs-national-cpi-comparison-61381d73 -d '<json body>'
```

Example prompt: Show me the Austrian HICP and national CPI annual rates side by side for food category CP01, including the percentage-point difference for each period where both series are published.

## When to prefer this

Choose this endpoint when you specifically need to compare Austria's harmonised (HICP) and national (VPI/CPI) food inflation measures for the same category and period — particularly to analyse methodology-driven divergence or policy reporting differences. Prefer it over single-index endpoints when both series are required simultaneously. Not suitable if you only need one index, non-food categories, or cross-country HICP comparisons.

## Known failure modes

- Invalid or unsupported COICOP category code returns an error (pattern must match ^CP01\d*)
- Category code with no published values for either series returns an empty or minimal result
- Mismatched periods where only one index has data are silently excluded, potentially returning fewer rows than expected
- Overly long or malformed category string rejected by pattern/length validation

## How this service works

Austrian food HICP and national CPI annual rates side by side with each published period and percentage-point difference for identical periods only. Example: category CP01. Different index methods remain separate; missing series are not inferred.

## Output

A structured list of periods for which both the Austrian food HICP and national CPI annual rates are published, with the HICP rate, the national CPI rate, and the calculated percentage-point difference for each matching period. Periods where only one series exists are excluded. The two index methodologies are kept separate and no missing values are inferred.
