Download Link

The /d/:key path serves files as downloads. The browser will prompt to save the file instead of displaying it inline.

Base URL

Downloads are served from https://cdn.atiru.io by default. If you configured a custom CDN, use your public_url_base instead.

Path: GET /d/:key

The :key is the file's file_id from the upload response.

Behavior

• Content-Disposition: attachment — triggers a download in the browser
• Filename: Uses the original filename from upload, or the file ID if no name was provided
• No transformation: Files are served as stored. No resize or format conversion (unlike /m/ for images)

Examples

Direct link (triggers download)

https://cdn.atiru.io/d/abc123

HTML link

<a href="https://cdn.atiru.io/d/abc123" download>Download file</a>

curl

curl -O -J "https://cdn.atiru.io/d/abc123"

The -O flag saves to a file, and -J respects the Content-Disposition filename.

Supported file types

All public files can be downloaded via /d/:key, including:

• Images
• Documents (PDF, Word, Excel, etc.)
• Archives (ZIP, RAR, etc.)
• Audio and video
• Fonts
• Any other allowed upload type

Caching

Responses include Cache-Control: public, max-age=31536000 (1 year).

Authentication

No authentication is required. The file must be public (is_public: true). Private files return 404.
