## 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 macrolens-gdp-analysis-api-88b86d84 -d '<json body>'
```

Example prompt: Can you pull up an AI-powered GDP analysis for Germany using MacroLens — I want current figures and economic context from FRED and World Bank data.

## When to prefer this

Choose this endpoint when you need AI-interpreted GDP analysis that combines FRED and World Bank data sources into a synthesized narrative, rather than raw GDP figures alone. Ideal for agents needing enriched macroeconomic context rather than just data retrieval.

## Known failure modes

- Invalid or unrecognized country name returns error or empty data
- Missing required 'country' field returns validation error
- Country not covered by FRED/World Bank datasets may return incomplete data
- Payment failure via x402/Base blockchain prevents API access
- LLM synthesis timeout may cause delayed or failed response
