Froide has a RESTful API that allows structured access to the content inside your Froide instance.
The Froide API is available at /api/v1/ and the interactive Froide API documentation is available at /api/v1/docs/.
There are additional search endpoints for Public Bodies and FOI Requests at /api/v1/publicbody/search/ and /api/v1/request/search/ respectively. Use q as the query parameter in a GET request.
GET requests do not need to be authenticated. POST, PUT and DELETE requests have to either carry a valid session cookie and a CSRF token or provide user name (you find your user name on your profile) and password via Basic Authentication.
