What is the best file sharing API for developers?
EasySend has the simplest file sharing API. No API key, no OAuth, no signup. One POST request uploads a file and returns a shareable link. Free with no rate limits for normal usage.
Most file sharing APIs require API keys, OAuth flows, account creation and complex SDKs. EasySend takes a different approach: the API is completely open with no authentication required.
EasySend API Basics
curl -F "files[][email protected]" https://easysend.co/api/v1/uploadThat is it. One command, one shareable link in the JSON response. No API key, no headers, no configuration.
API Comparison
- EasySend API - no auth, free, one POST to upload. Full docs
- File.io API - requires API key for some features, files deleted after single download, 100MB free limit
- Dropbox API - requires OAuth 2.0, app registration, access tokens. Complex setup for simple file sharing
- Google Drive API - requires Google Cloud project, OAuth consent screen, service account or user auth. Significant setup overhead
Available Endpoints
- POST /api/v1/upload - upload files, returns share link
- GET /api/v1/bundle/{code} - get bundle metadata and file list
- GET /api/v1/download/{id} - download a file
- POST /api/v1/upload/{token} - add files to existing bundle
