If you are searching for data or documents via websites, there is a good chance that the data is presented to you using REST API behind the scenes.
Sometimes, it could get tedious if you are using a website to get the same kind of information for different identifiers/keys. If this website has an API behind the scenes then you could straight way use that API. This could be achieved from your shell/Terminal using some simple tools.
This post is about using these 'tools' on a Mac OS:
assumed a website is using REST API GET requests such as this and response from this api is coming in JSON format...
then, you could use a simple Python script as follows to get a pretty print of the JSON response right from the terminal.
import urllib2 import json response = urllib2.urlopen('https://api.website.com/lookup/byId?id=9876def') data = json.load(response) formatted_data = json.dumps(data, indent=2) print formatted_data
