Overview

Welcome to Nasuni Data Service (NDS) for AWS API Documentation.

This documentation describes the S3-compatible, read-only endpoints exposed via AWS S3 Object Lambda for accessing data stored in a Nasuni Volume.

This API sits behind AWS S3 Object Lambda. Authenticate exactly as you would to S3:

• AWS Signature Version 4 (headers) — Signed requests include:

  • Authorization: AWS4-HMAC-SHA256 ...
  • X-Amz-Date: YYYYMMDD'T'HHMMSS'Z'
  • X-Amz-Content-Sha256: UNSIGNED-PAYLOAD
  • X-Amz-Security-Token (when using temporary credentials)

• Presigned URLs — Generated by AWS SDK/CLI. Credentials/signature appear as query params: X-Amz-Algorithm, X-Amz-Credential, X-Amz-Date, X-Amz-Expires, X-Amz-SignedHeaders, X-Amz-Signature, and optional X-Amz-Security-Token.

• ListObjects / ListObjectsV2: List files in a volume.
• HeadObject: Retrieve file metadata and headers.
• GetObject: Download file content; supports single byte-range requests.
