No there aren't. All HTTP traffic can be modified, which means it can deliver any malicious payload to the server or client. It's dangerous not to use HTTPS, period.
This is silly, as the endpoint you're connecting to could also be malicious. If you're worried about trusting your intermediary, you can just VPN to a trusted host and use it as a proxy.
Or you can SSH to the server and read it from http://localhost (if you have access). But there can still be malicious software running, intercepting syscalls or your localhost domain can point to a malicious IP. :/ Software can't be trusted. Period.
