# Official Inflation Rate Lookup (HICP / CPI-U)

> Official Inflation Rate Lookup (HICP / CPI-U) is a paid API for AI agents from x402-apis.pages.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-23).

Returns official consumer price inflation data (year-on-year) for 39 European countries plus the US, sourcing Eurostat HICP and BLS CPI-U, with up to 36 months of history and flash-estimate flagging.

## 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 official-inflation-rate-lookup-hicp-cpi-u-603cd225
```

Example prompt: What's the official year-on-year inflation rate for Germany right now? Pull the latest 6 months of history too so I can see the trend.

## When to prefer this

Choose this endpoint when you need official, government-sourced consumer price inflation data — not market forecasts or third-party estimates. It is the right choice for any agent answering macro questions about eurozone (HICP), EU member states, Norway, Switzerland, Turkey, or the US (CPI-U). Prefer it over generic financial data APIs when source attribution, flash-estimate flagging, and historical series up to 36 months are required, and when paying per-call in USDC micro-transactions (x402) is acceptable.

## Known failure modes

- HTTP 400 returned before payment is charged when country code is invalid or missing
- HTTP 400 if months parameter is outside 1–36 range
- Data unavailable for very recent months if the official statistical release has not yet occurred
- Service outage does not result in a charge
- Flash estimates may be revised in subsequent months

## How this service works

Use when an agent needs the official inflation rate (year-on-year consumer prices) for a country: Eurostat HICP for the euro area, EU and 36 European countries (incl. CH, NO, TR) and US CPI-U from the Bureau of Labor Statistics. Latest month plus up to 36 months of history, flash estimates flagged. Source named in every answer. Bad input: HTTP 400 before payment; outage is not charged.

## Output

A JSON object containing the country code, the latest month's year-on-year inflation rate with date and value, a time-series array of up to 36 monthly readings, a flag indicating whether the latest figure is a flash estimate, and a named source field (Eurostat HICP or BLS CPI-U).
