Now it is public so you can access using https://bard.google.com/Before to this, I received an email to join the beta or preview of bard. I believe that is because I am also part of Pixel Superfan community. 

Thanks, very eager to wait to get access and try it out. 

Thanks for sharing this info, I have joined the waitlist and also signed up for Google I/O. I live close so I can attend in person.I have a simple question.So it is under PalmAPI and not called as Bard API? Thanks,Vivek

looks like for enterprise customers it is through Vertex AI LLM. 

Same here. I've been waiting. I got the beta access when Bard first launched and been using since the first day. I wish we find a way to get access to API
