How to get your API key

Some image services (like Replicate) block direct browser calls (CORS). A free Cloudflare Worker acts as a bridge. Free · 100k requests/day · ~5-minute setup.

1. Sign up at cloudflare.com (free).
2. Workers & Pages → Create Worker.
3. Paste this code, deploy, then copy your worker URL into the tool.

export default {
  async fetch(req) {
    const target = "https://api.replicate.com" + new URL(req.url).pathname;
    if (req.method === "OPTIONS") {
      return new Response(null, { headers: {
        "Access-Control-Allow-Origin": "*",
        "Access-Control-Allow-Headers": "*",
        "Access-Control-Allow-Methods": "GET,POST,OPTIONS"
      }});
    }
    const res = await fetch(target, {
      method: req.method,
      headers: req.headers,
      body: (req.method === "GET" || req.method === "HEAD") ? undefined : req.body
    });
    const headers = new Headers(res.headers);
    headers.set("Access-Control-Allow-Origin", "*");
    return new Response(res.body, { status: res.status, headers });
  }
};
