I am using the AWS Price List Query API to get only pricing for EC2 and EBS services.
Is it free to use the AWS Price List API?
Do I also need to create a new client for every pricing call?
Below is the code that I use:
AWSPricing pricing_client = AWSPricingClientBuilder.standard()
.withCredentials(new AWSStaticCredentialsProvider(new BasicAWSCredentials("mycredentials")))
.withRegion(Regions.US_EAST_1)
.build();
Is it free to use the AWS Price List API?
Yes, using the AWS Price List API is free of charge.
Other paid APIs like the AWS Cost Explorer API mention pricing & have been listed on AWS Cost Management Pricing as having a cost associated with them.
The Price List API is not on the pricing page, nor has a cost mentioned anywhere in the documentation so it is safe to assume that it is free (after all, you're just getting AWS's pricing data).
Do I also need to create a new client for every pricing call?
No, it isn't needed nor recommended.
Use the same pricing client for as many calls as needed.
