domain expiration

Hello Guys, Overnight, I found out that one of my competitors domain expired, so I'm looking to buy that domain. The problem is when I access the domain I get a page saying the domain expired about a couple of days ago, but when I type the domain on "Whois", it says it won't expire until next...

Hi Im looking to make a Domain Expiration bot to tell me when a site I want is available for purchase. I have no idea where to get this data but Im sure its open to the public. Where can I find it? Thanks *I dont want to use a service Im learning how to code so I want to do it myself.
