## 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-analysis-aacbfd59 -d '<json body>'
```

Example prompt: Pull an AI-powered interest rate analysis from MacroLens starting from January 2022 — I want to understand the macro trend and what the data signals about monetary policy.

## When to prefer this

Choose this endpoint when you need not just raw interest rate data but also an AI-generated narrative interpretation of macro trends — it combines FRED's authoritative rate series with LLM analysis in a single call, saving the step of fetching data and prompting an LLM separately. Best for finance research agents, macro briefings, and investment analysis workflows where both data and human-readable insight are required.

## Known failure modes

- Invalid or missing start date returns a validation error
- Start date set in the future may return empty data or an error
- FRED data unavailability during outages may cause partial or failed responses
- Malformed request body returns a 400-level error
- x402 payment failure prevents the call from executing — USDC balance must be sufficient on Base

## How this service works
