Sadly. mcapi.ca was the best service so far.

I'm not sure. Maybe this will help? Unfortunately there is no English. But you can use a translator.
http://docs.ely.by/skin-system.html

It doesn't provide the data I need. A digital signature by Mojang is required otherwise the minecraft client will decline to accept the skin data.

This will help in solving the problem?

https://mineskin.org/
MineSkin.org allows you to generate skin texture data signed by Mojang.
These can be used on ingame skull blocks or to change a player's skin using some packet magic :).

[Lib] MineskinSponge - Easy texture to skin conversion
https://forums.spongepowered.org/t/lib-mineskinsponge-easy-texture-to-skin-conversion/16293

The goal of mineskin is only to generate custom skins not download them.

This is an unofficial client.

Sad. A dead end.

Not the same. TLauncher is patch supported version of Minecraft automatically.

There is a plugin (Bukkit/Spigot/Sponge). In 1.11.2 doesn't work. On 1.10.2 is not checked. I think you would be interested. ely.by/skinsystem-plugin/elyby-skinsystem-0.1.1.jar

Any news?

I found no alternative solution sorry.

Another question. Request to mojang is sent at every change of skin? Or load from the cache?

No it caches it in memory and in the database

That is enough to have one license client? Others will be able to install from the cache?

yes they will be only downloaded once

TLauncher (http://tlaun.ch/jar) somehow works with Ely.by. Unfortunately there is no source code. It is possible to decompile. Is it possible to integrate the plugin?

So this is a mod?
