Our API is designed to work with the speech recognition technology of your current voice supplier. If your voice supplier needs help recognising 3 word addresses, don't hesitate to get in touch.
The what3words API translates 3 word addresses to GPS coordinates. It does not provide map or routing data. However, our API does provide a layer that can be used with any mapping software, meaning it can work well as part of your existing mapping, addressing and route optimisation solutions.
The what3words API has a grid-section function (learn more at: https://developer.what3words.com/public-api/docs#grid-section). This returns grid lines for the area supplied in GeoJSON format, which can be directly added to a web map or desktop GIS such as QGIS. To add the what3words grid to a Google Map, watch this short tutorial: https://developer.what3words.com/tutorial/displaying-the-what3words-grid-on-a-google-map/
