Students will be able to...

• Make more request to an external api
• Wrap your request in Python methods and classes
• Register for a api key to use later(look at google api)

• Everything on the internet revolves around data. How do we grab it? Where can we get it? What can we do with it?

Five Min Exercise

• Read about Wrapper Functions

• A wrapper function is a subroutine in a software library whose main purpose is to call a second subroutine with little or no additional computation.
• Did you like that wiki description?
• In human words, a wrapper function is making your code more effienct and DRY by wrapping it in a method we can invoke when we need it.
• In terms of Python and APIs we want to wrap our api calls in a method so we don't have to fill our code repeating endpoints

• There are so many APIs, some are free and others require payment
• You may also stumble upon an API key requirement
• API keys are used by a web app to limit who and how many requests can be made to the API
• Some companies that are free but require a key are Rotten Tomatoes, Twitter, Facebook, Google Maps, and many more
• Usually you will request a key. If and when provided you will have to use that key in your Endpoint call
• When you get a key to an API make sure to see if and what the limit of requests are.

• If everybody gets a unique key how can we keep it safe so nobody steals it
• NEVER PUSH YOUR KEY TO GITHUB
• You can create a gitignore file and choose which files to not push to github
• You can also use Environmental Variables.

Five Min Exercise

• In yesterdays folder, outside the OMDB folder make a new folder
• Create a sqlite3 database in that folder
• Create a readme file and a py file
• Create a text file
• gitignore the text and database files
• push to github and see what happens

It may not make complete sense until next phase when we start building web applications that others can access

• We know that we can employ RESTful practices to API operations following CRUD and HTTP Verbs

• Remember APIs are not only external. Your SQLite MVC applications can and show follow RESTful practices

• Six Restful Rules From This Blog and also the REST Wiki

  • Client-Server
  • Stateless
  • Cacheable
  • Layered System
  • Uniform Interface
  • Code on Demand

• The same endpoint can be used multiple times. The HTTP Verb / Method is important in telling the application what the type of request is
