My Twitter Bot glowing brightest just before dying out! What to do with it's domain name?

I run a twitter bot @SearchThisImage which does reverse image search of tweeted images. I did this with an intention to help stop spread of misinformation. I assumed many of us would use reverse image search to validate / find more info of tweeted images. And instead of everyone doing the same search, if the searched result is available there itself, it will avoid that hassle. It kind of automates some of CommunityNotes' work. It started spreading slowly and got some eyes of fact checkers and OSINT groups. The adaption was not that great. When Twitter's API pricing came up, I thought it it time to shut down. But things took turn couple of days back. A person was surprised at the results of one of the searches and posted an image of the tweet. That went Viral and got more than 2M Views. I was surprised to know that Reverse Image search was new to many people on Twitter. They even thought this is AI to the next level because of the accuracy of the results. For the past 2 days, there is constant engagement and good uptick of follower counts. Only thing is it has deviated significantly from fact-finding to 'other' image searches. I even got couple of offers to buy the Bot.

I also have a website in the same name searchthisimage.com and have recently used it to push search results to a subdomain. I've pust some ads on it.

Now, I need some help in deciding what to do with the Bot and the website. Due to Twitter's API pricing, the bot is no longer affordable. If I decide to sell the website (I think can be turned to an independent Search web app), how should I valuate it?. How do I price-in the popularity of the bot name in the domain name sale?
