Bypass Medium WAF and reverse-engineer the API

Context: I am working on a project to automatically post to medium.
Iirc there's no API for medium.com .

I have been trying to bypass the Medium WAF using go-rod stealth but it flags and blocks me as a bot. What are your thoughts on this?

Also is there a way I can reverse engineer the medium API in some way? i have no experience in reverse engineering.
