Wasabi Storage

Wasabi is a cost-effective S3-compatible object storage with no egress fees — compared to AWS S3 (~$0.09/GB egress), Wasabi's no-egress model makes it attractive for large data sets that are frequently accessed or replicated. For agents: use standard boto3 with a custom endpoint — identical code as S3, just different endpoint URL. Good for backup storage, ML dataset storage, and media archives where egress costs would be prohibitive on S3. 30-day free trial. Confidence is docs-derived.

S3-compatible API via boto3 with Wasabi endpoint. s3 = boto3.client("s3", endpoint_url="https://s3.wasabisys.com", aws_access_key_id=access_key, aws_secret_access_key=secret_key). s3.create_bucket(Bucket="my-bucket"). s3.put_object(Bucket="my-bucket", Key="path/file.txt", Body=data). s3.get_object(Bucket="my-bucket", Key="path/file.txt"). s3.list_objects_v2(Bucket="my-bucket", Prefix="folder/"). s3.delete_object(Bucket="my-bucket", Key="path/file.txt"). Presigned URLs: s3.generate_presigned_url("get_object", Params={Bucket, Key}, ExpiresIn=3600). Regional endpoints: s3.wasabisys.com (us-east-1), s3.us-west-1.wasabisys.com, s3.eu-central-1.wasabisys.com, etc. Lifecycle: s3.put_bucket_lifecycle_configuration for object expiration rules.

Access key + secret key auth (same as AWS S3). Keys from Wasabi Console → Access Keys → Create New Access Key. Custom endpoint required — NOT the default AWS endpoint. HTTPS enforced. No IAM policies (Wasabi uses simplified permissions model). Bucket policies: apply via S3-compatible API for access control. Sub-account users: Wasabi supports sub-accounts for permission isolation.

S3-compatible: standard boto3 exceptions (ClientError with error code). Bucket minimum storage: Wasabi charges minimum 1TB/month per bucket regardless of actual usage — check billing model before creating many small buckets. Object minimum: 4KB minimum object size billing. Egress: free from Wasabi (key differentiator). Wasabi uptime at status.wasabi.com. Minimum retention: Wasabi requires 90-day minimum retention period — early deletion still billed. Regional performance: use closest regional endpoint for best latency.

docs.wasabi.com covers S3 API compatibility guide, boto3 configuration, SDK examples, and regional endpoint reference. Getting started: create Wasabi account (30-day free trial), create bucket, configure boto3 — first upload in under 5 minutes. Use standard boto3: pip install boto3. Regional endpoint selection is key for performance. Community via Wasabi support and developer documentation. Documentation is solid for the S3-compatible storage use case.
