## 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-interest-rates-api-274f3be7 -d '<json body>'
```

Example prompt: Pull MacroLens interest rate analysis starting from January 2022 and give me an AI-interpreted summary of how rates have trended since then.

## When to prefer this

Choose this endpoint when you need AI-interpreted interest rate data grounded in authoritative FRED and World Bank sources, especially when you want natural-language macro analysis alongside raw time series — rather than just querying raw FRED data yourself or using a generic financial data API without LLM interpretation.

## Known failure modes

- Missing required 'start' parameter returns a validation error
- Invalid date format for 'start' field may cause parsing failure
- FRED or World Bank upstream data unavailability may result in partial or empty data response
- Payment failure via x402/Base may prevent endpoint access
- LLM inference timeout for MiMo could delay or truncate the AI analysis
