Note that you'll need to:

- Set up a [ReplicateHQ](https://replicate.com) account to get the `REPLICATE_API_TOKEN` env var.

- Set up an [Upstash](https://upstash.com) account to get the Upstash Redis env vars.

- Create a [Cloudflare R2 instance](https://www.cloudflare.com/lp/pg-r2/) and set up a [Cloudflare Worker](https://workers.cloudflare.com/) to handle uploads & reads (instructions below).

### Cloudflare R2 setup instructions

1. Go to Cloudflare and create an [R2 bucket](https://www.cloudflare.com/lp/pg-r2/).

2. Create a [Cloudflare Worker](https://workers.cloudflare.com/) using the code snippet below.

3. Bind your worker to your R2 instance under **Settings > R2 Bucket Bindings**.

4. For extra security, set an `AUTH_KEY_SECRET` variable under **Settings > Environment Variables** (you can generate a random secret [here](https://generate-secret.vercel.app/)).

5. Replace all instances of `images.extrapolate.workers.dev` in the codebase with your Cloudflare Worker endpoint.

Cloudflare Worker Code

```ts

// Check requests for a pre-shared secret

const hasValidHeader = (request, env) => {

  return request.headers.get("X-CF-Secret") === env.AUTH_KEY_SECRET;

};

function authorizeRequest(request, env, key) {

  switch (request.method) {

    case "PUT":

    case "DELETE":

      return hasValidHeader(request, env);

    case "GET":

      return true;

    default:

      return false;

  }

}

export default {

  async fetch(request, env) {

    const url = new URL(request.url);

    const key = url.pathname.slice(1);

    if (!authorizeRequest(request, env, key)) {

      return new Response("Forbidden", { status: 403 });

    }

    switch (request.method) {

      case "PUT":

        await env.MY_BUCKET.put(key, request.body);

        return new Response(`Put ${key} successfully!`);

      case "GET":

        const object = await env.MY_BUCKET.get(key);

        if (object === null) {

          return new Response("Object Not Found", { status: 404 });

        }

        const headers = new Headers();

        object.writeHttpMetadata(headers);

        headers.set("etag", object.httpEtag);

        return new Response(object.body, {

          headers,

        });

      case "DELETE":

        await env.MY_BUCKET.delete(key);

        return new Response("Deleted!");

      default:

        return new Response("Method Not Allowed", {

          status: 405,

          headers: {

            Allow: "PUT, GET, DELETE",

          },

        });

    }

  },

};

```
