I’ve found that Google Cloud Platform (GCP) makes it a bit easier to get current pricing data, compared to Amazon Web Services (AWS). That said, after much searching, I had not found a method to access historical pricing without having to go through the pricing calculators they provide for older pricing.

Until now! You can access historical pricing by appending 'v3', 'v2', or 'v1' to the front of the URL provided by Google for their current pricing. Just a heads-up: you can access that link via HTTPS as well, and if you try to go from there to v1..v3 in a web browser, you might get a security warning, as the older pricing is served only by HTTP. That said, if you’re actually going to access the data, you’re probably not cutting and pasting from a web browser :)

Below is a simple example in Python for retrieving four sets of GCP pricing and storing it in a dict:

import requests

old_pricing = ['v1', 'v2', 'v3', 'current']
pricing = {}

for version in old_pricing:
    if version = 'current':
        url = 'http://cloudpricingcalculator.appspot.com/static/data/pricelist.json'
    else:
        url = ('http://{}.cloudpricingcalculator.appspot.com'
                '/static/data/pricelist.json').format(version)
    pricing[version] = requests.get(url).json()['gcp_price_list']

# then do whatever you want with the data 

That should work in Python 2.7.x and 3.x. You can leave out ['gcp_price_list'] if you want to get metadata as well as the pricing data. And, unlike AWS, you don’t need to build a scraper or have credentials to access this data, which is pretty sweet.
