# Openrouteservice
In order to use Openrouteservice's isochrone API, you will need to create an account on [their website](https://openrouteservice.org/log-in/). 
Once connected, go in your *Dashboard* and create an API token. 
Once generated it will show you the API key you can use in the dataiku application:

**:warning:  Openrouteservice's API is free but limits your daily API calls to 500: knowing that 5 locations can be passed through each API call (and this is what is done in the project). The API Dashboard will let you manually generate as many API keys as you need if you exceed that daily limit.**
