I think it's pretty close to perfect. I made a sample WrapAPI for http://etfdailynews.com/etf/{{symbol}}/ where the symbol is a 3-4 character ETF ticker symbol like VYM. It's one of the only websites I've found that provides the full breakdown of an ETF's contents. Initially I wasn't sure where to provide sample input such as a handful of ticker 3 character strings since /{{symbol}}/ isn't a GET or a POST value. So under the JSON and Table column I had multiple symbols separated by commas and it took me a little while before I realized that you were only supposed to supply one test value and where I was supposed to supply that test value. But it "clicked" shortly after.
