Serving with the OpenFisca web API

You can plug the OpenFisca web api to your country package.

First, install the OpenFisca web API:

pip install -e '.[api]'

Then run:

make run

You can make sure that the api is working by requesting:

curl "http://localhost:2000/api/2/formula/edat?data_naixement=1978-01-15"

A more complex example, create this file:

{
  "output_format": "variables",
  "scenarios": [
    {
      "test_case": {
        "families": [
          {
            "adults": ["pare1"],
			"menors": ["infant1"]
          }
        ],
        "persones": [
          {
            "id": "pare1",
            "data_naixement": "1961-01-15",
            "ingressos_bruts": "7000",
            "es_usuari_serveis_socials": true,
            "ciutat_empadronament": "Barcelona"
          },
          {
            "id": "infant1",
            "data_naixement": "2002-01-15",
            "es_usuari_serveis_socials": true,
            "ciutat_empadronament": "Barcelona"
          }
        ]
      },
      "period": "2017-1"
    }
  ],
  "variables": ["AE_230_mensual"]
}

and run:

curl http://localhost:2000/api/1/calculate -X POST --data @./the_file_you_created.json --header 'Content-type: application/json'
