# Teuerung Food HICP Multi-Country Comparison

> Teuerung Food HICP Multi-Country Comparison is a paid API for AI agents from teuerung.halowerk.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-21).

Compares food-category HICP inflation rates across multiple European countries for a specified COICOP category and reference period, without substituting zeros for missing observations.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 teuerung-food-hicp-multi-country-comparison-cd5bd45a -d '<json body>'
```

Example prompt: Can you compare the official HICP inflation rate for dairy and eggs (CP0112) between Germany, Austria, and France? I want to see the figures side by side without any zero-fill for missing data.

## When to prefer this

Use this endpoint when you need to directly compare food HICP inflation across two or more European countries for the same category and reference period, especially when data integrity matters and zero-filling of missing observations would distort the comparison. Prefer this over single-country endpoints when cross-national benchmarking is the primary goal. Best suited for economic analysis, retail pricing strategy, and policy research requiring official Eurostat-sourced figures.

## Known failure modes

- Invalid or unsupported COICOP category code returns an error or empty result
- Geo code not recognized as an EU/EFTA/candidate country returns a validation error
- Fewer than 2 countries specified triggers a schema validation error
- Missing Eurostat data for a country-period combination returns null rather than zero
- Category keyword not matched to a known COICOP code may return no results or ambiguity error
- API authentication or x402 payment failure blocks the request

## How this service works

Compare food-category HICP rates across reporting countries with an explicit reference period. Example: category CP0114, geos DE and AT. Missing source observations are never replaced by zero.

## Output

Returns HICP inflation rates (period-over-period and/or annual) for the specified food category, broken down by each requested country, along with the reference period and any flags for missing or unavailable source observations (which are left as null rather than replaced by zero).
