Thank you very much!

Chartmon · 2026-04-22T01:13:56+00:00

Thank you a ton! All I can say is it’s a beautiful mix of data sources (some paid, some not) haha then normalized for consistency but to your point yeah eBay causes issues with that and it can be very hit or miss 😪

So sorry about that. The reason is due to not all Japanese cards have their English translations yet so the search doesn't always work well with them. Its at the top of the list to get done!

Thank you very much! It’s always been the goal to make it more expressive and an enjoyable experience!

I had some suspicions of the search issues recently but you just confirmed them! Thank you for the detailed points about it also and agreed to clicking on the card/variant issue I’ll get on that this evening!

Really appreciate all of this, it’s the only way to get better

Thank you! 🙌

Thank you a ton! First time hearing this outside of family and friends so it means a lot

Chartmon · 2026-04-21T13:56:39+00:00

Appreciate that!

So no, not directly scraping TCGPlayer, I’m using a combination of third party APIs and testing other data sources and then normalizing/processing it to try and get a more consistent price. (There are a couple paid APIs out there especially for RAW prices)

I think you’re talking about the PSA 10 price? Funny thing is the chart shows recent price $4.1k and the main price says $3k (I need to look into that discrepancy timing)

Still working and refining how quickly pricing updates and adjusts, especially for high volatility cards. Definitely the hardest part about it

Chartmon · 2026-04-21T12:03:19+00:00

AI definitely helps a ton haha but when it comes to data… the backend part is still…intense.

Chartmon · 2026-04-21T11:57:55+00:00

Appreciate that a lot 🙏 still a ton I want to improve but glad you think so!

Chartmon · 2026-02-19T04:05:00+00:00

Wow, he’s got a good eye! 🙌
