Render.com's Free plan goes to sleep after 15 minutes of inactivity.  

As a workaround, this uses [cron-job.org](https://console.cron-job.org/), which sends periodic responses.  
Here are the steps I'm keeping a record of.

## 1. Go to cron-job.org and create an account

[cron-job.org](https://console.cron-job.org/)  

> Reference site  
> [Using cron-job.org to periodically access a specific URL](https://laboradian.com/access-url-using-cron-job-org/)

## 2. Create a JOB
From the Dashboard, click CREATE CRONJOB.

## 3. Configure COMMON
Set the URL and access frequency. Here I set it to 10 minutes.

This is the notification setting for when a run fails. (Optional)

## 4. Configure ADVANCED
Next, switch to the ADVANCED tab and configure it.

Finally, click the CREATE button to finish.
