This is a really simple REST API demo api (or an example if you want to fork it)

API Docs

API Endpoint Prefix: https://REST-Test-API.vandesm14.repl.co
/api/ - Returns the status of the api
/api/echo/:param - Returns :param
/api/echodbl/:param1/:param2 - Returns :param1, :param2
/api/echoquery/?q=* - Returns q

I hope this helps anyone who is interested in RESTful API's!
