  title: Filebase S3-Compatible Multipart Upload API
  description: The Filebase S3-Compatible API provides standard AWS S3 protocol support for bucket and object management. Developers can use any existing S3 SDK, CLI tool, or framework with endpoint s3.filebase.io and region us-east-1. Authentication uses AWS Signature Version 4 (AWS4-HMAC-SHA256) with Filebase access key and secret key pairs. Supported operations include bucket creation and deletion, object upload (including multipart), copy, delete, and listing. Objects stored in IPFS-backed buckets are automatically pinned with 3x geo-redundant replication.
