get ec2 pricing programmatically?

Question

Is there a way to get AWS pricing programmatically (cost per hour of each instance type, cost per GB/month of storage on S3, and etc)?

Also, are there cost monitorin

Answer 1

As Amazon has recently changed the pricing scheme for EC2 instances (no more Medium or Light, only Heavy which has multiple payment options - allUpfront, partialUpfront, noUpfront) and also some time ago separated the old generation instances from the current ones, the list of undocumented pricing API links has changed as well the structure of JSON provisioned by these links. The full list if links of EC2 pricing undocumented API with descriptions, as well as the Python module for convenient access and structured output of pricing in JSON, CSV or Table formats can be found in the following repository:

UPDATE:

There is now AWS pricing API: https://aws.amazon.com/blogs/aws/new-aws-price-list-api/

Orginal answer:

The price lists are available in form of JSONP files (you need to strip off function call) which are used by the AWS pricing pages. Each table (and each tab for table) has separate JSON file. It is not an API maybe, but definitely computer digestible. Here is a list that supports EC2 pricing page (as of 17 December 2014):

WARNING: The endpoints change from time to time and often old URL is still there with old values. It is best to check what is the current status rather than relying on links provided in this thread.

So, here is a short command to get current set or URLs from any AWS pricing page. Example based on EC2. Run it on Linux or Cygwin. Actually this command was used to create the list above.

curl http://aws.amazon.com/ec2/pricing/ 2>/dev/null | grep 'model:' | sed -e "s/.*'\(.*\)'.*/http:\\1/"

For those who don't like command line, you can also check in a web browser network console (you get there with F12), filter with JS objects:

Answer 3

If you're using Go, I wrote a package to decode the data into a struct, based on the files linked to in @okrasz's answer

Feel free to contribute with more pricing data.

Answer 4

I am the author of an open-source tool called ec2-cost-calculate that will "report your EC2 instance usage on an hourly basis" - the tool is available at awsmissingtools.com. Output can be hourly, daily, monthly. Two versions of the tool exist, one written in Ruby and another written in bash.

Answer 5

If you are using golang, I wrote a library that can query the data using the "https://pricing.us-east-1.amazonaws.com/offers/v1.0/aws/{offer_code}/current/index.{format}" format.

https://github.com/Chronojam/aws-pricing-api

import (
        "github.com/chronojam/aws-pricing-api/types/schema"
)

func main() {
        ec2 := &schema.AmazonEC2{}

        // Populate this object with new pricing data
        err := ec2.Refresh()
        if err != nil {
                panic(err)
        }

        // Get the price of all c4.Large instances,
        // running linux, on shared tenancy
        c4Large := []*schema.AmazonEC2_Product{}
        for _, p := range ec2.Products {
               if p.Attributes.InstanceType == "c4.large" &&
                       p.Attributes.OperatingSystem == "Linux" &&
                       p.Attributes.Tenancy == "Shared" {
                       c4Large = append(c4Large, p)
               }
        }
}
