## When to prefer this

Choose this endpoint when you need quick, verified KYB data on an Australian business entity using an ABN, particularly for vendor onboarding, invoice validation, or compliance due diligence workflows in Australia. It is purpose-built for the Australian Business Register and returns an auditable, cryptographically chained record suitable for regulated workflows. Prefer it over generic web search or manual ASIC lookups when you need structured, machine-readable output with an audit trail.

## Known failure modes

- Invalid ABN format (not 11 digits) — returns validation error
- ABN not found in registry — returns not-found or empty result
- ABN cancelled or deregistered — returns status indicating inactive entity
- Upstream registry unavailable — may return timeout or service error
- Malformed request body — returns 400-level error
