The SOS API is based on the S3 API.
Storing objects in SOS
Simple Object Storage (or SOS) is compatible with most of the Amazon S3 API. You can find more information about how to use SOS in our documentation.
Content length for POST operation is limited to 16 MB maximum.
Although we strive to maintain full compatibility with the S3 API, we do not support all S3 features. A complete list of unsupported features can be found here: List of unsupported S3 features.
Retrieving usage per bucket
You can retrieve a snapshot of total objects size per bucket using the listBucketsUsage Compute API call. Reported usage is updated on a daily basis.
