Suggest Addresses

client.addressVerification.suggestAddresses(, ?): AddressVerificationSuggestAddressesResponse { data, message, status }

POST/v1/addver/suggestions

Returns up to 3 verified address suggestions for a given input address.

Useful as a fallback when POST /verifications returns a failed status — suggestions represent the closest matches found and may help the user identify the correct address.

Accepts the same freeform or structured input formats as POST /verifications.

Uses 1 lookup per call (plus 1 more if geocoding).
