Mandinet Intelligence Layer — Demo v2

Cloudflare Worker Code — paste this into your Worker

export default {
  async fetch(request, env) {

    // Allow CORS from any origin (tighten to your domain in production)
    const cors = {
      'Access-Control-Allow-Origin': '*',
      'Access-Control-Allow-Methods': 'POST, OPTIONS',
      'Access-Control-Allow-Headers': 'Content-Type',
    };

    if (request.method === 'OPTIONS') {
      return new Response(null, { headers: cors });
    }

    if (request.method !== 'POST') {
      return new Response('Method not allowed', { status: 405 });
    }

    // Forward request to Anthropic API
    const body = await request.json();
    const response = await fetch('https://api.anthropic.com/v1/messages', {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json',
        'x-api-key': env.ANTHROPIC_API_KEY,   // stored as Worker secret
        'anthropic-version': '2023-06-01',
      },
      body: JSON.stringify(body),
    });

    const data = await response.json();
    return new Response(JSON.stringify(data), {
      status: response.status,
      headers: { ...cors, 'Content-Type': 'application/json' },
    });
  }
};

After deploying, your Worker URL will look like: https://mandinet-proxy.YOUR-SUBDOMAIN.workers.dev
Replace the API endpoint in this file: find PROXY_URL and paste your Worker URL there.

To use the proxy in this demo

In the API key field above, paste your Worker URL instead of an API key.
The demo detects whether you entered a URL (starts with https://) or a key (starts with sk-ant-) and routes accordingly.
Recipients open the HTML file, leave the key field blank, and click Run Claude — if a default proxy is configured, it just works.
