## 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-complying-development-certificates-nearby-search-aca912b7
```

Example prompt: Can you find all complying development certificates within 1 km of 45 George Street, Parramatta NSW and show me the ones lodged since 2023-01-01?

## When to prefer this

Use this endpoint when you need to discover CDC records geographically near a specific point in NSW, especially when you have a street address or coordinates and want proximity-ranked results. Prefer this over the search-by-council/suburb endpoint when location proximity matters more than administrative boundaries, and over the single-record endpoint when you don't yet know the specific certificate ID.

## Known failure modes

- Missing both address and lat/lng — endpoint requires at least one location input
- Invalid latitude or longitude values (out of WGS84 range)
- Radius exceeds 2000 metres maximum — capped or rejected
- Address not resolvable to a NSW location — geocoding failure
- Limit parameter out of range (must be 1–100)
- No CDCs found within radius — empty result set returned
- Payment failure or missing x402 payment header — 402 response
