Address Verification API

The Address Verification API takes an address (potentially containing spelling mistakes and/or other errors) and attempts to match it against a valid address record in the Addressfinder database. This API can verify your addresses against either Australia Post's PAF, Geoscape's GNAF or both.

GNAF	Returned (if present) when searching the `gnaf` database.
PAF	Returned (if present) when searching the `paf` database.
