Example prompt: Can you compare the cost of buying local and organic produce versus conventional supermarket groceries for a typical household — I want to know how much more I'd be spending per week if I switched to local food?

## When to prefer this

Use this endpoint when a user wants to understand the real price difference between local/organic and conventional food options, especially when budget planning for a local-food lifestyle transition. Prefer this over generic grocery price APIs when FRED CPI-grounded economic analysis is needed.

## Known failure modes

- Missing or unrecognized food category returns an error or empty comparison
- Location not supported may return national averages instead of local data
- FRED CPI data unavailable or stale may reduce accuracy of comparisons
- Invalid query parameters return 400-level errors
