Requester Pays Buckets
In general, bucket owners pay for all Amazon S3 storage and data transfer costs associated with their bucket. A bucket owner, however, can configure a bucket to be a Requester Pays bucket. With Requester Pays buckets, the requester instead of the bucket owner pays the cost of the request and the data download from the bucket. The bucket owner always pays the cost of storing data.
Typically, you configure buckets to be Requester Pays when you want to share data but not incur charges associated with others accessing the data. You might, for example, use Requester Pays buckets when making available large data sets, such as zip code directories, reference data, geospatial information, or web crawling data.
If you enable Requester Pays on a bucket, anonymous access to that bucket is not allowed.
You must authenticate all requests involving Requester Pays buckets. The request authentication enables Amazon S3 to identify and charge the requester for their use of the Requester Pays bucket.
When the requester assumes an AWS Identity and Access Management (IAM) role prior to making their request, the account to which the role belongs is charged for the request. For more information about IAM roles, see IAM Roles in the IAM User Guide.
After you configure a bucket to be a Requester Pays bucket, requesters must include
x-amz-request-payer in their requests either in the header, for POST,
GET and HEAD requests, or as a parameter in a REST request to show that they understand
that they will be charged for the request and the data download.
Requester Pays buckets do not support the following.
You cannot use a Requester Pays bucket as the target bucket for end user logging, or vice versa; however, you can turn on end user logging on a Requester Pays bucket where the target bucket is not a Requester Pays bucket.
DevPay and Requester Pays
You can use Amazon DevPay to sell content that is stored in your Requester Pays bucket. For more information, go to "Using Amazon S3 Requester Pays with DevPay," in the Using Amazon S3 Requester Pays with DevPay.
The charge for successful Requester Pays requests is straightforward: the requester pays for the data transfer and the request; the bucket owner pays for the data storage. However, the bucket owner is charged for the request under the following conditions:
The requester doesn't include the parameter
x-amz-request-payerin the header (GET, HEAD, or POST) or as a parameter (REST) in the request (HTTP code 403).
Request authentication fails (HTTP code 403).
The request is anonymous (HTTP code 403).
The request is a SOAP request.
