CAN I GET APPLE CARE ON MAGIC KEYBOARD

I have it, has worked great for 2 years. The cost of AppleCare for small items like the keyboard, even if offered, isn’t worth it. Worst case, buy new if out of warranty. If you don’t bang on the keyboard and don’t spill coffee, it should last a decade. Enjoy...

They make a lot of Magic Keyboards and you didn't say which one, but AppleCare+ for the iPad Pro also covers a new Magic Keyboard.
