user83074: I need to use some API in my project. So I'm gonna use such libraries as listed in the title? What GSM/SIM module do I need for this purpose? I've checked 800L and similar - it only can use plain http, and only via AT command. At least based on this, that's not what I really need. Thanks in advance.

user37622: The TinyGSM library implements the Arduino Client class required by networking super libraries you mention in the question.
TinyGSM supports the SIM800 modems.
