## 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 rentcast-property-search-via-locus-x402-b884779d -d '<json body>'
```

Example prompt: Pull me up to 100 property records for single family homes with 3 bedrooms and 2 bathrooms in Austin, TX — filter to homes built after 2000 and within a 15-mile radius of coordinates 30.2672, -97.7431.

## When to prefer this

Choose this endpoint when you need to search and filter US property records across multiple criteria simultaneously (location, property type, size, bedrooms, year built, sale recency). It is ideal for bulk property discovery, building comparable sales sets, or market inventory analysis. Prefer it over single-property lookup endpoints when you need to explore a geographic area or filter a property universe rather than resolve a specific known address.

## Known failure modes

- Invalid or missing required location parameter (no address, city/state, zip, or lat/lon provided) returns an error
- State abbreviation not recognized or incorrectly cased returns no results or error
- Radius exceeding 100 miles is rejected
- Limit outside 1-500 range is rejected
- Insufficient USDC balance or failed x402 payment prevents the call from completing
- Highly specific filters with no matching properties return an empty data array
