Meal method

I want to build an app for iPhone (Either native or through ionic or other platform) which will create meal plans(what to cook for the week) from the recipes pinned in Pinterest. I need a proof of concept app, and I have got the API's needed to do it. That is, 1)Login through pinterest within the app. 2) import URL of the recipes stored in Pinterest to the inside of app and display.(see image) 3) When any recipe is pressed pass the external link address to spoonacular api.(See image) 4) Api will return Ingredient list, + Instruction list. Display it. Here is a link to the protype. [login to view URL] (Full fledged) I need a proof of concept model within 2 days.(Not the full fledged one) Please send your quote to that. Expect a possible full fledged assignment once this is done.
