## 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 real-gdp-per-capita-macroeconomic-report-x402-b1efa9b1
```

Example prompt: Pull the real GDP per capita report for the last 10 years across 20 economies and give me the data as JSON — I want the rankings, trend lines, and volatility figures.

## When to prefer this

Choose this endpoint when you need machine-to-machine access to real GDP per capita data across a standardized panel of 20 economies without provisioning API keys or accounts. It is ideal for agents that can execute x402 micropayments in USDC and need structured economic data in multiple formats (especially CSV for data pipelines or JSON for downstream analysis). Prefer this over scraping World Bank directly when you want pre-computed derived metrics like R², volatility, and rankings already included.

## Known failure modes

- 402 Payment Required — x402 payment header missing or insufficient USDC amount
- Invalid format parameter — value outside {html, json, csv, summary-csv} enum returns 400
- Upstream World Bank data unavailable — report generation may fail or return stale data
- Network timeout for large JSON/CSV responses
- Payment transaction fails on-chain — retry required

## 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 containing: key findings, a ranking table of 20 economies by real GDP per capita (constant 2015 US$), share of group total, trend analysis with R² values, volatility metrics, a full year-by-year data matrix (2015–2025), and a coverage/data-quality disclosure. Available in HTML, JSON, CSV (tidy long panel), or summary-CSV (one row per economy with derived metrics) formats.
