Example prompt: Can you look up the Australian company registered under ABN 51824753556 — I need their business name, whether they're active, their GST status, and registered address?

## When to prefer this

Use this endpoint when you need to verify or enrich Australian business data using an ABN, confirm GST registration, or validate a business's active status against the official Australian Business Register. Prefer this over generic business search APIs when you have a specific ABN and need authoritative government-sourced data.

## Known failure modes

- Invalid ABN format (not 11 digits) returns validation error
- ABN not found in ABR returns empty or not-found response
- Network or upstream ABR service unavailability causes timeout
- Malformed query parameter causes bad request error
