Comms.ID Address

Australian address autocomplete

Suggest, resolve and validate Australian addresses from G-NAF, the national address file. Every answer comes from Australian address data, and the address text a user types is not logged. Free under fair use.

Try it

Quickstart

Sign in to the Companion App and register your app. Enable Address only.
Create your app's key pair on your server; Companion registers the public key.
Call the API with a short-lived token signed by your key:

curl -X POST https://api.comms.id/address/v1/suggest \
  -H "authorization: Bearer $(npx comms-id token address)" \
  -H "content-type: application/json" \
  -d '{"query":"1 george st syd"}'

Reference: comms.id/docs/address. For agents: llms.txt.

Operations

POST /address/v1/resolve — Resolve one suggested address identifier to a structured address.
POST /address/v1/suggest — Suggest Australian addresses for partial text, as the user types.
POST /address/v1/validate — Check one typed address against the supported source. Not proof that mail can be delivered there.

How it compares

Comms.ID Address answers from G-NAF, does not log the address text a user types, and is free under fair use. Each cell below quotes the vendor's own public page, with the date it was read. Where a page does not say, the cell says so; nothing is inferred.

Coverage and limits

Coverage: every address in G-NAF, in every Australian state and territory.
Validation reports a match against G-NAF. It is not proof that mail can be delivered.
On this page, each visitor may make 10 requests per 10 seconds and 40 requests per 60 seconds. Over the limit, the reply is 429 FAIR_USE_CEILING with Retry-After.
A registered app starts with 150 requests for each product and each day (an owner's apps share one daily total). Over it, the reply is 429 FAIR_USE_CEILING with Retry-After and the reset time. A verified owner can ask for a higher ceiling in the Companion App.
At 150 requests, the Address element (1.0.0) completes about 75 addresses a day for a person who types the whole address at 40 words per minute. How this was measured, and the limit for slower typists.
