Overview

Storj is a decentralized cloud storage platform that splits, encrypts, and distributes files across thousands of independent nodes worldwide. Unlike traditional cloud storage, no single server holds your complete file, which gives you stronger privacy and data resilience. Use the Storj API to upload objects, manage buckets, generate presigned download URLs, and control access credentials.

💡

Beginner Tip

Storj offers an S3-compatible gateway (link.storjshare.io) so you can test uploads with the same curl commands you would use against AWS S3 — just swap the endpoint URL and use your Storj Access Grant as the credential.

Common Errors & Troubleshooting

401 Unauthorized Missing or incorrect API key / Access Grant in the Authorization header.
✓ Generate an Access Grant in the Storj web console and pass it as the Bearer token: `Authorization: Bearer <access-grant>`.
No such bucket (404) The bucket name in your request does not exist in your project.
✓ Create the bucket first via the dashboard or the `storj mb sj://bucket-name` CLI command before making API calls against it.
Upload hangs or times out Large files uploaded without multipart chunking can exceed connection limits.
✓ Use Storj's multipart upload API for files over 64 MB, or switch to the CLI/SDK which handles chunking automatically.
