Okay, So you want to connect a lot of APIs. But for what? Do trade or tracking portfolio? You can do both of these with Bituniverse: https://bot.bituniverse.org/ I am using this and found it very decent. You can use a lot of bot for free from here. I am using it since the beginning and found it very profitable also. You don't need to pay any money for this. Try it, hope you will like it.
