Starting today, the AWS Price List API can return product and pricing information for specific AWS services and regions. Previously, the API returned product and pricing information for a service for all AWS regions at once. You can now create more precise requests that return product and pricing information for the AWS service and region of interest.

For example, using this API you can get the product and pricing information for Amazon S3 in the us-east-1 region:

https://pricing.us-east-1.amazonaws.com/offers/v1.0/aws/AmazonS3/current/us-east-1/index.json or https://pricing.us-east-1.amazonaws.com/offers/v1.0/aws/AmazonS3/current/us-east-1/index.csv
