Launify Address API

The Launify Address API powers address typeahead, structured address autocomplete, and reverse geocoding. It returns ranked, deduplicated suggestions biased to a location, with rich structured details for each result.

What you can do

• Address search — free-text typeahead. One query string, ranked address suggestions.
• Structured search — field-by-field autocomplete (city, street, zip, house number…).
• Reverse geocode — find the nearest known addresses to a coordinate.
• Authentication — API keys, allowed domains, and how the ACL works.

Quickstart

1. Get your API key

Your key is issued together with the domain(s) it may be used from. A key only works when the request originates from an allowed domain.

2. Make your first request

Code(bash)
 
curl -G 'https://api.polaris.launify.com/address_whisper' \
  -H 'Referer: https://yourapp.com' \
  --data-urlencode 's=Národní 223' \
  --data-urlencode 'country=CZ' \
  --data-urlencode 'apiKey=YOUR_API_KEY'

3. Render the suggestions

Each result has a ready-to-display label, GPS coordinates, and a structured details object you can store. See the response shape.

Conventions

• Transport — GET requests, JSON responses, UTF-8.
• Coordinates — WGS-84 (lon, lat) in decimal degrees.
• Country codes — ISO 3166-1 alpha-2 (e.g. CZ, SK), case-insensitive.
• Location bias — pass lon/lat to rank nearby results first.
