Are there any API's for Amazon Web Services PRICING? [closed]

Solution 1:

UPDATE:

AWS has pricing API nowadays: https://aws.amazon.com/blogs/aws/new-aws-price-list-api/

Original answer:

This is something I have asked for (via AWS evangelists and surveys) previously, but hasn't been forthcoming. I guess the AWS folks have more interesting innovations on their horizon.

As pointed out by @brokenbeatnik, there is an API for spot-price history. API docs here: http://docs.amazonwebservices.com/AWSEC2/latest/APIReference/ApiReference-query-DescribeSpotPriceHistory.html

I find it odd that the spot-price history has an official API, but that they didn't do this for on-demand services at the same time. Anyway, to answer the question, yes you can query the advertised AWS pricing...

The best I can come up with is from examining the (client-side) source of the various services' pricing pages. Therein you'll find that the tables are built in JS and populated with JSON data, data that you can GET yourself. E.g.:

• http://aws.amazon.com/ec2/pricing/pricing-on-demand-instances.json
• http://aws.amazon.com/s3/pricing/pricing-storage.json

That's only half the battle though, next you have to pick apart the object format to get at the values you want, e.g., in Python this gets the Hi-CPU On-Demand Extra-Large Linux Instance pricing for Virginia:

>>> import json
>>> import urllib2
>>> response = urllib2.urlopen('http://aws.amazon.com/ec2/pricing/pricing-on-demand-instances.json')
>>> pricejson = response.read()
>>> pricing = json.loads(pricejson)
>>> pricing['config']['regions'][0]['instanceTypes'][3]['sizes'][1]['valueColumns'][0]['prices']['USD']
u'0.68'

Disclaimer: Obviously this is not an AWS sanctioned API and as such I wouldn't recommend expecting stability of the data format or even continued existence of the source. But it's there, and it beats transcribing the pricing data into static config/source files!

Solution 2:

For the people who wanted to use the data from the amazon api who uses things like "t1.micro" here is a translation array

type_translation = {
    'm1.small' : ['stdODI', 'sm'],
    'm1.medium' : ['stdODI', 'med'],
    'm1.large' : ['stdODI', 'lg'],
    'm1.xlarge' : ['stdODI', 'xl'],
    't1.micro' : ['uODI', 'u'],
    'm2.xlarge' : ['hiMemODI', 'xl'],
    'm2.2xlarge' : ['hiMemODI', 'xxl'],
    'm2.4xlarge' : ['hiMemODI', 'xxxxl'],
    'c1.medium' : ['hiCPUODI', 'med'],
    'c1.xlarge' : ['hiCPUODI', 'xl'],
    'cc1.4xlarge' : ['clusterComputeI', 'xxxxl'],
    'cc2.8xlarge' : ['clusterComputeI', 'xxxxxxxxl'],
    'cg1.4xlarge' : ['clusterGPUI', 'xxxxl'],
    'hi1.4xlarge' : ['hiIoODI', 'xxxx1']
}
region_translation = {
    'us-east-1' : 'us-east',
    'us-west-2' : 'us-west-2',
    'us-west-1' : 'us-west',
    'eu-west-1' : 'eu-ireland',
    'ap-southeast-1' : 'apac-sin',
    'ap-northeast-1' : 'apac-tokyo',
    'sa-east-1' : 'sa-east-1'
}
