Kelsey Hightower mentioned Zeit last year and I've been meaning to look into it. It's a pretty awesome serverless platform.
I didn't use their now client, I just added a repo to Zeit and it manages the build and deployment for me.
Here's a link to the repo: https://gitlab.com/hooksie1/zeit-test
This was written in Go. Using Go you just need an exported Function and take the http.responseWriter and the http.Request. Then do you work on the payload and return the info.
Here's the URL for the endpoint: https://goniq.hooks.technology/api/test
You can test it by giving it a list of strings and it will return only the unique strings. For example:
curl -X POST https://goniq.hooks.technology/api/test -d '{"list": ["testing","testing2","testing3","testing2", "mangolassi", "mangolassi"]}'
It will return this data for you:
["testing","testing2","testing3","mangolassi"]
