Extract data from Recipes

Hi

I need to extract data from all recipes :

I tried this
mywebsiteURL/wp-json/wp/v2/cooked_recipe

with this you get 10 recipes as this is the default returned number of recipes defined by API REST.

You can get methods for cooked_recipe at http://herbalgetresults.tk/wp-json/wp/v2/

I tried to used ?per_page=99 to increase the number of recipes listed but it doesn’t work.
Could it be possible for you to have a look at this please ? I am sure you are more skilled than in wordpress and developping.

Thank you
