## 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

```

## When to prefer this

Use this endpoint when you need to search across multiple NSW complying development certificates using filters like suburb, postcode, council, or date range. Prefer this over the single-record CDC endpoint when you don't have a specific application ID and need to discover or enumerate certificates. Use the NSW Development Applications search endpoint instead if you are looking for full DA applications rather than CDCs.

- Postcode not 4 digits returns validation error
- offset exceeding 1000 returns error
- limit outside 1-100 range returns validation error
