Kartpunkt's answers, by what you are building. Each page has an example call and its answer.

## Use cases

- [Trip logs](https://kartpunkt.se/en/use-cases/trip-logs): an official address for each trip's start and end in a körjournal, from the vehicle's GPS position.
- [School transport platforms](https://kartpunkt.se/en/use-cases/school-transport): for platforms that build school-transport products, road distances on foot or by car from many homes to a few destinations, with NVDB's facts along each route.
- [Address validation at checkout and in a CRM](https://kartpunkt.se/en/address-validation): check an address as typed, and say what is wrong instead of correcting it.
- [Road context](https://kartpunkt.se/en/use-cases/road-context): the road at a coordinate, with its speed limit, road owner and surface.
