## 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-lookup-5c41b622 -d '<json body>'
```

Example prompt: Can you pull the MacroLens series data for FRED series ID 'UNRATE' so I can see the historical US unemployment rate time series?

## When to prefer this

Use this endpoint when you need raw time series data for a specific known FRED or World Bank series ID. Ideal for agents that already know the series identifier (e.g. 'UNRATE', 'GDP', 'CPIAUCSL') and need to retrieve its historical data programmatically with micro-payment via x402 on Base.

## Known failure modes

- Invalid or unknown series_id returns an error or empty data
- Series ID not found in FRED or World Bank datasets
- Payment failure via x402/Base blockchain returns 402 response
- Network timeout from upstream FRED or World Bank APIs
- Malformed request body missing required series_id field
