The what3words Public API converts between three-word addresses and latitude / longitude coordinates, offers an AutoSuggest with autocorrect for voice/typing input, exposes supported languages and locale variants, and returns grid sections as GeoJSON. The API is HTTPS GET only, authenticated by API key in a query parameter or X-Api-Key header, and is wrapped by official SDKs for Swift, Android, Java, JavaScript, Python, PHP, and .NET, plus UI components for map and OCR experiences. image: https://kinlane-productions.s3.amazonaws.com/apis-json/apis-json-logo.jpg tags: - Geocoding - Addressing - Location - Three Word Address - Maps created: '2026-05-23' modified: '2026-05-23' specificationVersion: '0.19' apis: - aid: what3words:public-api name: what3words Public API description: >- REST API for converting between three-word addresses and latitude / longitude coordinates, with AutoSuggest, available-languages, and grid-section endpoints.
