Python script for automating registration via API with email, OTP, and proxy

It is necessary to develop a Python script that automatically registers accounts on the target platform. Registration is carried out in stages: via temporary email, OTP code, phone, password, and agreement to the terms. All requests must be sent through HTTP(S) proxy. The use of browsers (Selenium, Puppeteer) is prohibited. The developer must be able to build the script in such a way as to avoid automatic blocking by the platform.
