Will the CS key be tradeable?

PonyExpress · March 11, 2020

Can I check which key the user has:

The key can be tradable in 7 days (Old key)
The key was bought in the game and it can not be traded or sold never (New key)

Here are the data I get using manager.getUserInventoryContents(FRIEND_SID, 730, 2, false, (ERR, DATA)

Old key:

As I see, I have to check to see the parameter "marketable"?

Should this parameter always be true for all old keys and false for all new keys? Regardless of how the key was received (on the market / trade / purchased in the game long ago).

Thanks.

I can't guarantee it's going to work for you forever, but I would guess that checking the marketable property is a reliable way to see if a key is temporarily or permanently untradable.

Thank you for your quick response.

Is there any information about all the properties? I would like to know more about the differences between market_hash_name and market_hash and some others.

appid, contextid, assetid, classid, instanceid, amount, name, market_name, market_hash_name
- See this guide
id
- Same as assetid
pos
- Not always present; this is the item's position in the user's inventory (starting at 1)
background_color
- Hex code for the background color rendered for this item in the Steam inventory
name_color
- Hex code for the name and border color rendered for this item in the Steam inventory
icon_url
- Append this to https://steamcommunity-a.akamaihd.net/economy/image/ to get the item's image
descriptions
- Array of objects containing human-readable description text lines
tradable, marketable
- Self-explanatory
type
- The text that goes under the game's name to the right of the square game logo in the Steam inventory when this item is viewed
commodity
- Determines whether this item's Market listing uses buy orders exclusively (true), or individual listings with the possibility to submit buy orders (false)
market_tradable_restriction
- Length in days that this item will be untradable after it's bought on the market
market_marketable_restriction
- Length in days that this item will be unmarketable after it's bought on the market
tags
- Array of tag objects; tags are used in the Steam inventory for filtering
is_currency
- Always going to be false except for some Spiral Knights stuff (I think). You really don't want to deal with currencies, trust me.
fraudwarnings
- Array of warnings that will be rendered in red when this item is viewed. If fraudwarnings exist, the item gets a red (!) icon in the Steam inventory

I'll just leave it in case someone needs.
