The OLDP API is based on Django’s Rest framework extension (with Django-Rest-Swagger).

Authenticating with the API

Reading our data is possible without logging in. However, be aware of a stricter throttle policy for anonymous users (see Throttle rates). Write operators require authentication for which two methods exist:

  • Username and password: Use HTTP BasicAuth to login with your login credentials.
  • API Key: In your user settings you can request a specific API key that allows you to authenticating with the API.

Throttle rates

Spending resources carefully is of high importance for a non-profit project like ours. Hence, we limit the usage of our API as following (taken from oldp/settings.py):

  • Anonymous users: 100 requests/day
  • Registered users: 5000 requests/hour

If you need to do more requests, check out our data dumps or contact us. Our data is meant to be share - throttling is use a matter of limited resources.

For terminal-loving developers, curl is also always an option. Examples can be found on ${SITE_URL}api/schema/.

# List cities
curl -X GET "${SITE_URL}api/cities/" -H  "accept: application/json" -H  "api_key: ${API_KEY}"

# Get cases from court with id=3
curl -X GET "${SITE_URL}api/cases/?court_id=3" -H  "accept: application/json" -H  "api_key: ${API_KEY}"
