I like how you've thought through the end to end use case: not just generating an API, but actually making it usable. I've done my fair share of web scraping and it's not an easy task to make accessible and reliable -- good luck!

It makes me wonder if there isn't a whole "API to web/mobile app with custom metadata" product in there somewhere. I can imagine a lot of folks starting to get into data analysis and pipelines having an easier time of it if they could just create a visual frontend in a few clicks.
