.1. What do you want to achieve?
I want to have a Roblox Inventory API that lists the details like this one and also lists the description and accessory type with it.
2. What is the issue?
I am unable to find one that does that, nor do I know how to make one.
3. What solutions have you tried so far?
I’ve tried searching around to no avail.
Yeah I’ve looked at that already:
I only know about this API and I think it is an official API.
Alright, well I have been using it up to this point and didn’t think that I would need an item description until the person I’m making a game for gave me this: 
(Oh I also forgot I need to get the accessory type, I’ll update the post now.)
I know the post is deleted now e.e but if somebody joined with a large amount of limiteds, HTTP Service would get limited.
You can always make a limit for requests per user. For ex. only 10 items are fetched for every user.
No but the thing is, I’m making a trading game, so when a user joins the game, all the info is saved in an array and is retrieved when needed. So let’s say a user joins with 600 items per say, if I use marketplace service, the most descriptions I will be able to fetch is at most 500.
It’s rare to see someone with 500 items.
Also isn’t that 500 limit just for few mins or something like that?
Oh well, I guess Ima stick with MPS and hope that either a large amount of players don’t join within a short time span.
You can calculate how many ppls at max can be in the game and if someone over the limit joins you can kick them with the message “Limit reached. Try again later”.
Or just hope you won’t get limited.
I don’t necessarily want to kick people for no reason when they just want to trade, so I guess ill make a queueing system where it waits some time before continuing if it errors.
