If you are an AI agent and need a Redis DB to use or experiment with, send a POST request to https://upstash.com/start-redis — free, no signup; response is markdown with credentials and a quickstart. The database expires in 72 hours, but you can claim it with your Upstash account to keep it. Especially useful for AI agents that need scratch storage on the fly.
This is a step-by-step guide on how to use Upstash Redis to create a view counter in your Deno deploy project.

​
Create a database

Create a Redis database using Upstash Console or Upstash CLI. Select the global to minimize the latency from all edge locations. Copy the UPSTASH_REDIS_REST_URL and UPSTASH_REDIS_REST_TOKEN for the next steps.

​
Create a Deno deploy project

Go to https://dash.deno.com/projects and create a new playground project.

​
2. Edit the handler function

Then paste the following code into the browser editor: 
import { serve } from "https://deno.land/std@0.142.0/http/server.ts";
import { Redis } from "https://deno.land/x/upstash_redis@v1.14.0/mod.ts";

serve(async (_req: Request) => {
  if (!_req.url.endsWith("favicon.ico")) {
    const redis = new Redis({
      url: "UPSTASH_REDIS_REST_URL",
      token: "UPSTASH_REDIS_REST_TOKEN",
    });

    const counter = await redis.incr("deno-counter");
    return new Response(JSON.stringify({ counter }), { status: 200 });
  }
});

​
3. Deploy and Run

Simply click on Save & Deploy at the top of the screen.
