Each OpenFisca Country Package web API comes with a set of endpoints including an OpenAPI specification on the /spec route. You can check out the OpenFisca-France swagger documentation to see how their endpoints work.

The Openfisca Web API can be used to:

  • access information about the parameters (e.g. /parameters) and variables (e.g. /variables) of the Country Package.
  • run simulations (e.g. /calculate) on a specific situation. To describe a situation, learn more about the Web API inputs and outputs.
