## 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 macroeconomic-gdp-growth-rate-report-api-x402-8b6e42dc
```

Example prompt: Pull the latest GDP growth rate report covering the last 10 years across 20 economies and give me the data as JSON, including rankings and trend analysis.

## When to prefer this

Choose this endpoint when you need structured, multi-economy GDP growth data with derived analytics (rankings, R², volatility) out of the box, without managing API keys or subscriptions. It is ideal for agents that need to pay per-fetch rather than maintaining a billing relationship, and when you want a ready-made report rather than raw indicator data from a source like World Bank directly. Prefer it over general-purpose economic data APIs when you want the data pre-processed into rankings and trend statistics across a fixed panel of 20 economies.

## Known failure modes

- Payment not included or insufficient USDC — returns HTTP 402 requiring x402 payment header
- Invalid format query parameter value — server may reject or ignore the parameter
- Upstream World Bank data unavailable — report may be stale or incomplete
- Network timeout if the report is large and connection is slow
- Free preview endpoint may be used accidentally instead of the paid full report

## How this service works

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

## Output
