vim.api.nvim_create_user_command("TestCommand", function(opts)
end, { count = 1 })

vim.keymap.set("n", "<C-x>", "<cmd> TestCommand <CR>")

This will always print 1, even if I call the keybind with a number prefix. Is there a way to pass the count to the user command using the Lua API?

Since you're using count = 1, i.e., your command can take a count in the "line number position," consider using:

vim.keymap.set("n", "<C-x>", ":TestCommand <CR>")

The default behavior of : is to place the count before the command.

Another option is to create an expression map which uses v:count inside the command

vim.keymap.set("n", "<C-x>", function() 
     return "<cmd>echo " .. vim.v.count .. "<cr>" end, {expr = true})
