## 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 re-oracle-production-up-railway-app-1c858518 -d '<json body>'
```

Example prompt: Search the RE Oracle for residential properties in Austin, Texas with 3 bedrooms under $500,000 — I want to see what's available in that market.

## When to prefer this

Use this endpoint when you need to query real estate property data via a decentralized oracle approach with micropayment access, particularly when integrating into Web3 or x402-protocol-compatible workflows where pay-per-call pricing is acceptable.

## Known failure modes

- Invalid or missing search query returns 400 error
- Payment not included or insufficient USDC triggers 402 payment required
- Malformed POST body returns validation error
- No results found for overly specific criteria returns empty result set
- Service unavailability returns 500 error

## Output

Returns real estate search results matching the query criteria, including property listings, details, and relevant market data sourced from the RE Oracle.
