## 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 reportbazaar-2021-world-economy-yearbook-api-525cd4fc
```

Example prompt: Pull the 2021 World Economy Yearbook report as JSON so I can analyze GDP growth, inflation, and unemployment trends across the 20 economies covered from 2017 to 2021.

## When to prefer this

Choose this endpoint when you need a pre-packaged, analysis-ready macroeconomic report for 20 economies covering 2017–2021, and you want to pay per-fetch in USDC with no account or API key setup. It is ideal for agents that need structured economic panel data (GDP, inflation, unemployment, population) quickly and programmatically. Prefer alternatives if you need real-time or post-2021 data, a different set of economies, or custom indicator selection.

## Known failure modes

- Payment not included or insufficient USDC — returns HTTP 402 with payment required details
- Invalid format query parameter — returns error or ignores and defaults
- Network timeout if the report server is unavailable
- Upstream data unavailable or stale — report may reflect cached or incomplete World Bank data

## How this service works

Machine-to-machine macroeconomic report API. Pay per fetch in USDC over x402. No accounts, no API keys.

## Output

Returns a structured report covering 20 economies and 5 World Bank indicators (GDP current US$, GDP growth %, inflation %, unemployment %, total population) for the years 2017–2021. Output includes key findings, a ranking table, share-of-group totals, trend lines with R², volatility metrics, a full year-by-year data matrix, and a coverage/data-quality disclosure. Available in HTML, JSON, CSV (long panel), or summary-CSV (one row per economy).
