## New Feature

**Market Search: Search by radius**

`POST /market/search` now takes a `radius` as well as `coordinates`. Send a center point and a distance in miles (up to 25) to get every property within that distance:

```json
{
  "radius": { "lat": 41.8868, "lon": -87.6374, "miles": 1 }
}
```

Radius results are sorted by distance and each property includes `distance_miles`. If more than 2,500 properties match, you get the 2,500 closest.

Send either `radius` or `coordinates`. Sending both, or neither, returns HTTP `422`. Polygon searches work the same as before.

See the new [Market Search](/docs/market-search) guide for examples.
