How to track the value of your collection via AI

I’ve been experimenting with tracking the value of my collection using AI. I tried using ChatGPT and managed to input an Excel list of my items, but the values it provides are often inaccurate or outdated since ChatGPT doesn’t have direct access to live websites. Even when I specify to pull prices from eBay, 130point, or Fanatics, or ask it to give me values from recent months, it still doesn’t get the numbers right.

Has anyone else had experience with this or found a solution? Any ideas on what I could try?

I do not think a LLM is a good approach to help you here. They are not good with staying up-to-date and they are not good at understanding numbers and mathematics. So asking it to keep up-to-date averages is like asking Superman to hold a bucket of kryptonite.

At best, ChatGPT can probably be helpful at writing scripts that will help you extract information from websites

Oh the script writing is a good Idea. Do you have an idea what good prompt would be? I never worked with scripts before.

My original idea was not to have an LLM that automatically keeps up to date but rather ask it every once in a while to gather the current value of the items.

I’d recommend just using something like PokeDATA - Track your Pokemon Collection and Monitor your Portfolio of Investments! instead of trying to make something yourself. Obtaining ebay sold listing data is either quite fiddly & annoying (if you choose to scrape it yourself) or expensive (if you use someone elses api)

Thank you for the Idea. I was also checking that out, but some prices are quite off. And they are missing a bunch of cards in their library.

Have you tried Collectr

Probably the same issue of prices not being 100% accurate. I have my sealed stuff tracked on that app and use it for a rough outline.

Yep, unfortunately the same issue. They are missing a lot of Japanese cards and some prices, are even further off than PokeData.

I know nothing about coding…and tried to accomplish something that you’re looking to do.

TCGPlayer doesnt give out their API anymore…however, I found from my research this endpoint that I believe you can make your own excel “Scraper”. It is manual setup…but its possible. Here is the end point that should help you get started.

The attached picture is how I set up my excel sheet

Nice! Any idea how to do this with a site that tracks JP card prices?

LLMs, are essentially built on / trained on a digest of information that aggregates and compounds over time with diminishing returns as time goes on. Gen AI can change it’s own methods, disregard arbitrarily, yata… math… yata… Because of this, the AI we have now (non Gen AI) has a hard time adjusting to current information without also factoring in old information. I bet it would be good at giving you a growth over time value, but current values change too quickly, ironically, for our AIs to keep up. What you might do though, is break the problem down. AI is great at solving small problems we’ve already solved. :rofl:

Try using it to produce a smaller dataset, maybe prices at a certain time? no. you tried that… hmm. Something to think about. Maybe use AI to automagically do what @hero above said you could do.

Also, I’m fairly certain that some versions of chatbots or different service tiers (I’m not sure which) have access to live information, while others do not.

Just checked out that website, that’s super cool! Great tool and I will be using it :slight_smile:
