## 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-b0302988 -d '<json body>'
```

Example prompt: Pull an AI-powered interest rate analysis from MacroLens starting from January 2022 — I want FRED-backed data with an LLM summary of the trends.

## When to prefer this

Choose this endpoint when you need AI-synthesized macro analysis of interest rates backed by authoritative FRED data, rather than raw rate feeds alone. It is especially valuable when you want both structured time-series data and an LLM-generated narrative interpretation in one call. Prefer this over generic financial data APIs when you want macro-level commentary, not just numbers.

## Known failure modes

- Missing or malformed 'start' date parameter returns a validation error
- Start date too far in the past may result in data unavailability from FRED
- LLM (MiMo) generation failure may return a success:false with an error message
- x402 payment failure (insufficient USDC, wrong network) blocks the request entirely
- Rate limits or Vercel cold-start timeouts may cause intermittent failures
