Business Verification API for KYB and Onboarding
Resolve any Australian entity and screen it against sanctions and banned-persons registers in one call, joined from every free Australian government register with the Australian business data API. Built for customer onboarding and know-your-business checks.
Every register, one call
ABR, ASIC, ACNC, ORIC, GLEIF, and Super Fund Lookup, joined into a single verified record.
POST https://api.auo.com.au/v1/resolve Authorization: Bearer auo_sk_test_... { "abn": "46008583542" }
One request resolves the entity against the Australian Business Register (ABR) for status and GST, ASIC for company and business-name detail, ACNC for charity registration, ORIC for Indigenous corporations, GLEIF for the global LEI cross-walk, and Super Fund Lookup for superannuation fund status. Every field carries the register it came from and the date it was read.
Built for Tranche 2 due diligence
From 1 July 2026, full obligations commence under the AML/CTF Amendment Act 2024 for newly captured sectors: real estate, lawyers and solicitors, accountants, conveyancers, trust and company service providers, and precious-metals and stones dealers. These businesses must now run customer due diligence before providing a service, and screen for sanctions and politically exposed persons. The API gives you the entity-resolution and screening building blocks for that program: verified identity, ownership-adjacent structure, and possible-match screening, all sourced from free public registers. Read more in our Tranche 2 AML/CTF screening guide.
Screening built in
Every resolve call can include a possible-match screen against the DFAT sanctions consolidated list and the ASIC banned and disqualified persons and organisations registers. A hit is always returned as a review, never as a pass, fail, or clearance, and always names the underlying register. See the sanctions screening API for the dedicated screening endpoint.
| Register | Verdict | Meaning |
|---|---|---|
| DFAT sanctions | review | Possible name match, needs human review |
| ASIC banned persons | no match found as of 2026-07-05 | Not a clearance |
Honest boundaries
This is verification and monitoring, not a full KYB or customer due diligence platform. There is no free public register of directors, shareholders, or beneficial ownership for an ordinary Australian company, so we do not return it. An ACN is returned only for a company acting in its own right: a trust has an ABN but no ACN of its own, and its corporate trustee is a separate entity we resolve and screen in its place. We would rather state the boundary plainly than have you find it in production.
Business verification questions.
Is this a full KYB solution?
No. This is verification and monitoring across free public Australian government registers, not full KYB or customer due diligence. There is no directors, shareholders, or beneficial ownership data on the free sources we use.
Which registers do you check?
ABR, ASIC (companies, business names, banned and disqualified persons and organisations, AFS and credit licensees), ACNC, ORIC, GLEIF, and Super Fund Lookup, joined into one call.
Does it cover Tranche 2 requirements?
It gives you the identity and screening checks that sit inside a Tranche 2 customer due diligence program: entity resolution, sanctions and banned-persons screening, and ongoing monitoring. You still need your own AML/CTF program and reporting obligations. See our Tranche 2 guide.
Do you provide beneficial ownership?
No. There is no free public register of directors, shareholders, or beneficial ownership for ordinary Australian companies. We say so plainly rather than paper over the gap.
