## 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-series-data-endpoint-ce5b62ab -d '<json body>'
```

Example prompt: Pull the FRED series data for UNRATE — I want to see the US unemployment rate time series from MacroLens.

## When to prefer this

Choose this endpoint when you need structured macroeconomic time-series data identified by a known FRED series ID, especially when you want AI-enriched economic analysis layered on top of raw FRED and World Bank data, and are comfortable paying per-call via x402 on Base.

## Known failure modes

- Invalid or non-existent series_id returns an error or success:false
- Missing required series_id field causes a validation error
- Payment failure via x402 protocol blocks access
- FRED or World Bank upstream data source unavailable causes timeout or error
- Rate limiting or quota exhaustion on the paid API
