## 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 suverse-macro-cpi-inflation-world-bank-annual-inflation-time-series-14fc2fd5 -d '<json body>'
```

Example prompt: Can you pull the annual CPI inflation time series for Turkey from the World Bank? I want to see how inflation has evolved year by year.

## When to prefer this

Choose this endpoint when you need authoritative, World Bank-sourced annual CPI inflation data for any country by ISO code, especially for macroeconomic analysis, real return calculations, inflation regime identification, or monetary policy context. Prefer this over general economic APIs when you specifically need a clean yearly time series of consumer price inflation backed by World Bank methodology.

## Known failure modes

- Invalid or unrecognized ISO country code returns an error or empty result
- Country has no World Bank CPI data for certain years, resulting in null values in the time series
- World Bank upstream data unavailable or stale, causing degraded or cached response
- Malformed POST body or missing required fields returns a 400-level error
- Payment failure (x402) if the $0.004 USDC micropayment is not correctly processed
