## 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 economy-openverbs-inflation-cpi-history-4210c18f -d '<json body>'
```

Example prompt: Can you pull the World Bank inflation and CPI history for Brazil for the last 5 years? I want to see the annual consumer price inflation percentage and the price index trend.

## When to prefer this

Prefer this endpoint when you need reliable, World Bank-sourced annual inflation and CPI history for a specific country, especially for economic research, country risk assessments, or trend analysis. It is ideal when you need IMF-attributed data with explicit null-handling and clear index-base (2010=100) semantics. Not suitable for monthly inflation releases, real-time price data, cross-country price-level comparisons, or regional aggregates.

## Known failure modes

- Invalid ISO3 country code returns an error (no region aggregates supported)
- Requesting more than 10 or fewer than 1 year returns a validation error
- Countries with sparse World Bank data may return nulls for some years
- Payment failure via x402 protocol blocks the response
- Source data lag may mean the most recent calendar year is incomplete and excluded

## How this service works

Country inflation and CPI history from World Bank WDI: annual consumer-price inflation (%) and consumer price index (2010=100), by ISO3 country for the last 1-10 complete years. Includes independent latest values, units, nulls, source update date and IMF/CC BY attribution. Annual history, not monthly releases or forecasts; CPI levels do not compare prices across countries.

## Output

Returns a structured response containing annual consumer price inflation (%) and CPI values (indexed to 2010=100) for the requested country over the specified number of complete calendar years, plus the latest observed values, units, any null/missing observation flags, source update date, and IMF/CC BY attribution metadata.
