## 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 financial-data-x402-housing-market-fc7fa6b7
```

## When to prefer this

Choose this endpoint when you need a quick, self-contained snapshot of the most important U.S. housing market metrics in a single call, without managing API keys or subscriptions. It is ideal for agents that need pay-per-call access via USDC over the x402 protocol, covering mortgage rates, construction activity, and home price appreciation in one response.

## Known failure modes

- Payment not provided or insufficient USDC — returns 402 Payment Required
- Upstream data source temporarily unavailable — series appears in failed_series array
- Malformed request parameters — returns 400 Bad Request
- Network timeout or provider downtime — returns 5xx error

## How this service works

Pay-per-call stock, macro, on-chain, and crypto data over the x402 protocol. USDC on Base or Solana, no API keys, no subscriptions.
