M2M Verification API

Query any ABN or NZBN in real time. Government-anchored identity for AI agents and platforms. No login required.

Overview

The Osapher M2M (Machine-to-Machine) Verification API is a public endpoint that returns government-anchored business identity for any Australian ABN or New Zealand NZBN in real time. No API key, no login, no registration required.

It is designed for AI agents, enterprise compliance platforms, and developer tools that need to verify a business identity programmatically — without navigating government web portals or parsing raw registry schemas.

This endpoint is currently in public beta and is rate-limited for stability. Data is sourced from public government registries and is not an official government record.
