Generate an Australian address API client in 60 seconds

20 July 2026 · 3 min read

WattleAddr now publishes a full OpenAPI 3.1 description of every endpoint, so your existing tools can write the request code for you.

The spec is live and public

It’s served straight from the API, unauthenticated (and you can try every call live in the interactive reference), at:

https://api.wattleaddr.com.au/v1/openapi.json

The servers block points at production, so anything you paste it into talks to the production API, not a mock.

Three ways to use it

• Explore it visually: open our interactive reference and call autocomplete and retrieve live in the browser, no key required.
• Generate an SDK: run the spec through openapi-generator, Speakeasy, Kiota or similar to scaffold a typed client in TypeScript, Python, Go, PHP or your language of choice.
• Import into Postman or Insomnia: use the ready-made collection at /v1/postman.json to click through every endpoint.

Why this matters for a small, onshore provider

With a machine-readable contract, your client code does not drift from the API. The spec is the source of truth. Our own test suite checks live responses against it on every run, so what you generate matches what you get. An Australian-owned, onshore provider should still give developers the tooling the large offshore providers do.
