This page helps you connect to CoreWeave AI Object Storage by selecting an authentication method, configuring an S3-compatible client, and starting to work with objects in your buckets. It’s for developers and operators who prepare applications or tools to interact with Object Storage.

​
Authentication methods

Object Storage supports several authentication methods. Choose the method that best fits your use case, then continue to Configure your client. For production workloads, Workload Identity Federation with OIDC provides a secure authentication method. Your applications obtain tokens from your identity provider and exchange them for temporary CoreWeave access credentials that automatically expire. In Kubernetes environments, the Container Credentials API enables automatic credential rotation without application changes. For setup details, see Configure AWS CLI and boto3.

​
Process Credential Provider

For environments that need interactive sign-in flows or custom token exchange, AWS SDKs support a Process Credential Provider that invokes a custom command to fetch and refresh credentials. This approach works for both human and machine workloads. For examples, see Configure AWS CLI and boto3.

​
Static credentials

For initial testing and development, you can use static Access Keys created through the Cloud Console. Static credentials are long-lived and require manual rotation, so they aren’t recommended for production use.
Static Access Keys are a security risk in production environments because they are long-lived and can be leaked. Use Workload Identity Federation instead.

​
Configure your client

After choosing an authentication method, configure your S3-compatible client:

​
Work with objects

With authentication set up and your client configured, you’re ready to interact with your data. You can manage objects in your buckets, including uploads, listings, deletions, and renames. For endpoint configuration details, including virtual-hosted addressing and LOTA endpoints, see Set endpoints.
