With NameCheap API, I can get the domain availability and prices. Now you can find suitable names and related domains.
I thought it was easy. However, I still need set up a new development and production server to host Django with dockers.
After that, I set up a web service to connect with NameCheap. From the process, I learn that there may be a space to simplify the API set up procedures.
Let me know if you have any feedback for 3sName!
