That makes sense. I just don’t think the economics work for anyone to spend time developing this. It would take work to get to the point where it’s functional (which is potentially quite expensive). Beyond that, a domain name is $10-$15 a year and hosting would be $5-$7 a month. For $0.65 per request, it’s just not worth it.
I’d need a little over a hundred requests a year to break even on just mandatory external costs (development costs are harder to estimate and would almost certainly be 10x, 20x or more of the other costs).
