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 demonstration swagger documentation to see how the endpoints work.

The Openfisca Web API can be used to:

  • access information about the parameters (e.g. /parameters), the variables (e.g. /variables), and entities (e.g. /entities) 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,
  • analyse a simulation calculation (e.g. /trace) on a specific situation.
