Taxonomy API

We have a basic taxonomy API to get information about a taxonomy.

Eg. to get information about en:carrots entry in categories taxonomy:

https://world.openfoodfacts.org/api/v2/taxonomy?tagtype=categories&tags=en:carrots

you can add lc (language code) parameter to ask for more than one language. cc is used for country code.

Eg. to add french information on previous request:

https://world.openfoodfacts.org/api/v2/taxonomy?tagtype=categories&tags=en:carrots&lc=en,fr&cc=fr
