So midjourney is very 'casse couille'. They don't provide api access and using MJ through a third party tool is forbidden.
I don't really know what I have to do. Should I try to use self hosted solution (or tier hosted because I don't have the hardware) ?
it will be much more harder because MJ is a super multi model.
Another pain, this solution requires hosting solution.
Perhaps PaaS or SaaS solution already exists
