http-only site to test REST requests?

After the latest move by httpbin to HTTPS, apparently all sites that accepted test REST requests have disappeared. I've checked all mentioned in this post, and either they do not allow all kind of requests, or have also moved to HTTPS. In perl 6 modules such as this one, LWP::Simple, we need a HTTP-only site due to problems with certain operating systems. So is there any site left or will we have to roll out our own server?
