Get Autocomplete Advanced Previews

GET/v1/intl_addver/completions

Returns address completion previews for a partial address string, suitable for populating an autocomplete dropdown.

Regular mode — supply partialStreet to search by partial street address. Results may include Address types (resolvable directly) and Container types (buildings/complexes that require a follow-up call).

Advanced mode — supply advanced=true and a container ID (from a previous regular call) to drill into a building or complex and retrieve individual unit addresses.

Results with type: "Address" can be fully resolved by passing their id to POST /completions.

Does not consume a lookup.

data: array of object { id, description, error, 3 more }

The unique identifier for this result. Pass this to POST /completions to retrieve the full address. If the type is Container, pass it as the container parameter to GET /completions to drill down further.

error: optional string

An error message if the lookup failed for this result.

highlight: optional string

Character ranges within text that match the search input, for bolding in UI.
