## 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-indicator-lookup-api-7d08bdf2 -d '<json body>'
```

Example prompt: Pull the MacroLens analysis for FRED series CPIAUCSL — I want to see the latest consumer price index data with AI interpretation.

## When to prefer this

Choose this endpoint when you need structured macro-economic indicator data combined with AI-generated interpretation for a specific FRED or World Bank series ID. It is especially useful when you want both raw time-series data and LLM-powered analysis in a single call, rather than querying FRED or World Bank directly and interpreting the data yourself. Prefer this over raw FRED API access when AI narrative context is needed alongside the numbers.

## Known failure modes

- Invalid or unknown series_id returns success: false with no data
- Missing required series_id field causes request validation error
- Network or upstream FRED/World Bank API unavailability causes failure
- Payment not completed (x402) results in 402 Payment Required response
- Rate limiting or quota exceeded on the underlying data sources
