## 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 property-memoryapi-org-20adc698
```

Example prompt: What's the current median home price for the Austin metro area, and how has it changed over the last 12 months compared to the national figure?

## When to prefer this

Use this endpoint when you need current US home price levels or trends — either at the national level (FRED median) or for a specific metro (Zillow ZHVI) — with YoY change and a 12-month history series. Prefer this over raw FRED or Zillow APIs when you need a unified, pre-normalized response without managing multiple data source integrations.

## Known failure modes

- Unsupported or unrecognized metro area name returns an error or empty result
- FRED or Zillow data source temporarily unavailable causing fetch failure
- Missing required geographic parameter returns a validation error
- Data lag: most recent month may not yet be available from upstream sources
