Contabo Object Storage provides buckets and objects through an S3-compatible interface. Its documentation lists EU, US Central and Singapore endpoints. Choose the correct region and configure the S3 credentials separately from management API credentials.
Capacity is added in 250 GB steps. Optional automatic expansion has an account-level monthly cap. Object size, bucket count, API request rate and bandwidth have documented limits. Check the current account offer and quotas before planning large transfers or relying on old public prices.
