Hello, I have a static website that I want to do a couple asnychronous requests for data, used to render some data visualizations.I could do it on the website's javascript itself, except for the API keys needed to access the third party. So instead I'll put the API keys on the server and get the data and serve the result to the website.Heroku cost $25/month. I can think of an AWS lambda + database that would theoretically be cheaper, or theoretically more expensive. But what would you guys use?
