## 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-search-00a03841
```

Example prompt: Find me the 20 most recent development applications lodged in Surry Hills, NSW — filter to only residential development types and show anything lodged from 2024-01-01 onwards.

## When to prefer this

Use this endpoint when you need to search or browse NSW development applications across multiple records with filtering by geography (council, suburb, postcode), time (lodgement date range), cost, status, or type. Prefer this over the single-record endpoint when you don't have a specific application ID and need to discover or enumerate applications matching criteria.

## Known failure modes

- Invalid postcode format returns no results or an error
- Council name not matching any known council returns empty results
- Date range parameters in wrong format (not yyyy-mm-dd) may cause errors
- Offset exceeding 1000 or limit outside 1-100 range may return validation errors
- Payment failure ($0.01 USDC) results in a 402 response and no data returned
