The five endpoints

Everything you need to put an address in its place.

POST /v1/validate

Validation

Parse a messy human-typed address, match it against G-NAF Core, and get back a canonical record with a score and component-level results. Abbreviations, missing units and wrong postcodes are handled at request time.

POST /v1/geocode

Geocoding

The same matching engine, returning coordinates and the geocode type that produced them.

GET /v1/autocomplete

Autocomplete

Lightweight suggestions for address fields. An identifier and a label, nothing heavier.

GET /v1/addresses/{id}

Address details

A direct lookup on a known identifier. No fuzzy logic, no score, just the full record.

GET /v1/reverse-geocode

Reverse geocoding

Coordinates in, nearby addresses out, ordered by distance calculated per request.

Three calls from nothing to a resolved address.

Create a key

Sign up, create a key in the dashboard, and copy the secret. It is shown once. Keys are scoped to your account and can be revoked at any time.

Send an address

Post whatever your users typed. Normalisation and parsing happen server side, so you do not need to clean the input first.

curl https://auadr.arpanlabs.com/v1/validate \
  -H "Authorization: Bearer $ADDR_KEY" \
  -d '{"address":"181 fitzroy st st kilda 3182"}'

Read the match

Use match_quality to decide whether to accept the result, ask the user to confirm, or reject it. Store address_id so later lookups skip matching entirely.

"match_quality": "exact" | "partial" | "none"

Coverage

Matched against G-NAF, not guessed from a postcode file.

Every result traces back to a persistent G-NAF identifier, so an address you validate today is the same address you look up next year.

A G-NAF match confirms the address exists in the national dataset. It is not a postal deliverability certification, and we do not claim otherwise.

Coordinates are supplied in GDA2020, on EPSG:4326 axes, with latitude and longitude given to eight decimal places. There is no international fallback: an address outside Australia does not match, and the response says so.
