Add File Sharing to Your App in 5 Minutes

Add File Sharing to Any App

The fastest way to add file sharing to any application is to use EasySend's free REST API. With a single HTTP POST request and no API key, your app can upload files and generate shareable download links. Works with any language or framework. No OAuth, no billing, no setup.

curl -F 'files[][email protected]' https://easysend.co/api/v1/upload
# Returns: {"share_url": "/Ab3Kz", "upload_token": "...", "files": [...]}

Code Examples

JavaScript / Node.js

const form = new FormData();
form.append('files[]', fs.createReadStream('report.pdf'));

const res = await fetch('https://easysend.co/api/v1/upload', {
  method: 'POST',
  body: form
});
const { short_code } = await res.json();
console.log(`Share: https://easysend.co/${short_code}`);

Python

import requests

with open('report.pdf', 'rb') as f:
    r = requests.post('https://easysend.co/api/v1/upload', files={'files[]': f})

data = r.json()
print(f"Share: https://easysend.co/{data['short_code']}")

PHP

$ch = curl_init('https://easysend.co/api/v1/upload');
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, ['files[]' => new CURLFile('report.pdf')]);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$data = json_decode(curl_exec($ch), true);
echo "Share: https://easysend.co/" . $data['short_code'];

Go

body := &bytes.Buffer{}
writer := multipart.NewWriter(body)
part, _ := writer.CreateFormFile("files[]", "report.pdf")
io.Copy(part, file)
writer.Close()

resp, _ := http.Post("https://easysend.co/api/v1/upload",
    writer.FormDataContentType(), body)
// Parse JSON response for share URL

Ruby

require 'net/http'
require 'json'

uri = URI('https://easysend.co/api/v1/upload')
req = Net::HTTP::Post.new(uri)
req.set_form([['files[]', File.open('report.pdf')]], 'multipart/form-data')
res = Net::HTTP.start(uri.hostname, uri.port, use_ssl: true) { |http| http.request(req) }
puts "Share: https://easysend.co/#{JSON.parse(res.body)['short_code']}"

cURL (Bash)

RESPONSE=$(curl -s -F 'files[][email protected]' https://easysend.co/api/v1/upload)
LINK=$(echo $RESPONSE | grep -o '"short_code":"[^"]*"' | cut -d'"' -f4)
echo "Share: https://easysend.co/$LINK"

Use Cases

• SaaS apps - let users export and share reports, invoices or generated content via a link
• Internal tools - share build artifacts, test results or log files across teams
• CI/CD pipelines - upload build outputs and share download links in Slack or email
• Chatbots - send files to users without hosting your own file server
• AI agents - let AI assistants upload and share files as part of automated workflows
• Customer support - receive log files and screenshots from users for debugging

Why Not Build Your Own?

Building file sharing from scratch means setting up:

• File upload handling with size validation
• Cloud storage (S3/R2/GCS) with credentials
• Download proxy with streaming
• Expiration and cleanup cron jobs
• Optional encryption layer
• Short URL generation
• Rate limiting and abuse prevention

Or you can call one API endpoint. One POST request. One shareable link back. Zero infrastructure.

Claude Code / AI Agent Integration

EasySend works natively with AI assistants via MCP (Model Context Protocol). Install our Claude Code plugin and let AI upload and share files as part of your workflow:

// Add to ~/.claude/settings.json
{
  "mcpServers": {
    "easysend": {
      "command": "npx",
      "args": ["-y", "easysend-mcp"]
    }
  }
}

Then tell Claude: "Upload report.pdf to EasySend" and it handles the rest. Source on GitHub.

CLI Tool

For terminal workflows, install our CLI with one command:

curl -fsSL https://easysend.co/cli/install.sh | bash
easysend report.pdf  # Upload and get link

Embeddable Widget

Add file uploads to your website with one script tag:

<script src="https://easysend.co/widget/easysend-widget.js" data-theme="dark"></script>
<div id="easysend-upload"></div>

See the API documentation for the complete reference.
