## 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 nsw-development-applications-nearby-search-e50fc352
```

Example prompt: Can you find all NSW development applications within 1 km of 42 George Street, Parramatta NSW, lodged after 2024-01-01? Show me up to 30 results, nearest first.

## When to prefer this

Use this endpoint when you need to find development applications geographically near a specific NSW address or coordinate, especially when proximity ordering matters. Prefer this over the search-by-council/suburb endpoint when the user has a specific location (address or lat/lng) and wants results sorted by distance. Use the radius_m parameter to tighten or widen the search area (up to 2 km). Use the full-record endpoint when you already have a DA identifier and need complete application details.

## Known failure modes

- Neither address nor lat/lng provided — returns error requiring at least one location input
- Address cannot be geocoded to an NSW location — returns geocoding failure
- radius_m outside 1–2000 range — returns validation error
- limit outside 1–100 range — returns validation error
- lodged_from date in invalid format — returns date parse error
- No development applications found within the specified radius — returns empty results list
- Payment not included or insufficient — returns 402 Payment Required
