Example prompt: Can you pull up an AI-powered analysis of interest rate trends starting from January 2022 using MacroLens — I want to understand how rates have moved and what the macro picture looks like?

## When to prefer this

Choose this endpoint when you need both raw interest rate data and AI-generated macro-economic interpretation in a single call, particularly when analyzing Federal Reserve policy trends, comparing historical rate cycles, or building reports that combine quantitative FRED data with qualitative LLM-driven insights. Prefer over raw FRED API access when narrative context or synthesis is needed alongside the numbers.

## Known failure modes

- Missing or invalid 'start' date string returns an error or empty dataset
- Malformed date format causes request failure
- FRED data unavailable for the requested range returns partial or empty data
- Payment not provided or insufficient results in HTTP 402 rejection
- LLM analysis timeout may cause delayed or truncated AI commentary
