## 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 stationfx-median-sales-price-of-new-houses-sold-u-s-69a27b0a
```

Example prompt: Pull the StationFX median sales price of new houses sold in the U.S. for the last 12 months and show me the month-over-month and year-over-year percent changes in JSON format.

## When to prefer this

Choose this endpoint when you need U.S. new construction home price data with pre-computed derivatives (MoM, YoY, z-scores, percentile ranks, rolling averages) in a single call, rather than fetching raw Census Bureau or FRED data and computing statistics yourself. Ideal for housing affordability analysis, macro dashboards, real estate market monitoring, and consumer wealth trend assessments at monthly frequency.

## Known failure modes

- Invalid date format returns a 400-level error
- date_from after date_to returns empty or error response
- Requesting fields not in the schema returns unknown field error
- Payment not completed (x402) results in 402 Payment Required response
- Dates outside available historical range return empty data array
