Steam Community Inventory Skill

Retrieve and browse a Steam user's inventory from steamcommunity.com.

Setup

Find your Steam ID (SteamID64):
Go to your Steam profile page
If your URL is https://steamcommunity.com/profiles/76561198012345678, your Steam ID is 76561198012345678
If your URL uses a vanity name like https://steamcommunity.com/id/myname, visit steamid.io and paste your profile URL to get your SteamID64
Get your Steam session cookies (required to bypass rate limits when fetching your own inventory):
Log in to steamcommunity.com in your browser
Open Developer Tools (F12) > Application tab > Cookies > https://steamcommunity.com
Copy the value of the steamLoginSecure cookie
Set environment variables: bash export STEAM_ID="your-steamid64" export STEAM_COOKIES="steamLoginSecure=your-cookie-value"

Usage

All commands use curl to hit the Steam Community inventory endpoint. The context ID is 2 for all standard game inventories.

Common App IDs

Game	App ID
CS2 / CS:GO	730
Team Fortress 2	440
Dota 2	570
Rust	252490
PUBG	578080
Steam Community (trading cards, etc.)	753

Get inventory for a game

Replace $APP_ID with the game's App ID (see table above). Context ID is 2 for all standard game inventories.

curl -s "https://steamcommunity.com/inventory/$STEAM_ID/$APP_ID/2?l=english&count=2000" 
  -H "Cookie: $STEAM_COOKIES" | jq '.'

Get CS2 inventory

curl -s "https://steamcommunity.com/inventory/$STEAM_ID/730/2?l=english&count=2000" 
  -H "Cookie: $STEAM_COOKIES" | jq '.'

Get a summary of items (names and quantities)

curl -s "https://steamcommunity.com/inventory/$STEAM_ID/730/2?l=english&count=2000" 
  -H "Cookie: $STEAM_COOKIES" | jq '[.descriptions[] | {market_hash_name, type}]'

Get item details (asset IDs mapped to descriptions)

curl -s "https://steamcommunity.com/inventory/$STEAM_ID/730/2?l=english&count=2000" 
  -H "Cookie: $STEAM_COOKIES" | jq '{assets: [.assets[] | {assetid, classid, instanceid, amount}], total: .total_inventory_count}'

Paginated fetch (for inventories over 2000 items)

The API returns a last_assetid field when there are more items. Pass it as start_assetid to get the next page:

curl -s "https://steamcommunity.com/inventory/$STEAM_ID/730/2?l=english&count=2000&start_assetid=$LAST_ASSET_ID" 
  -H "Cookie: $STEAM_COOKIES" | jq '.'

Check for more pages by looking at the more_items field in the response (equals 1 if there are more).

Response Format

The inventory endpoint returns JSON with these key fields:

Field	Description
`assets`	Array of items with `appid`, `contextid`, `assetid`, `classid`, `instanceid`, `amount`
`descriptions`	Array of item metadata: `market_hash_name`, `name`, `type`, `icon_url`, `tradable`, `marketable`, tags, etc.
`total_inventory_count`	Total number of items in the inventory
`more_items`	`1` if more pages available (absent otherwise)
`last_assetid`	Last asset ID returned; use as `start_assetid` for next page
`success`	`1` if the request succeeded

Assets are linked to descriptions via classid + instanceid.

Notes

Rate limits: The community endpoint is heavily rate-limited by IP. Using your own cookies bypasses this for your own inventory. Without cookies, expect IP bans after a few requests (cooldown ~6 hours).
Spacing: If fetching multiple inventories or pages, wait at least 4 seconds between requests.
count parameter: Max value is 5000, but 2000 is recommended to avoid issues.
Context ID: Use 2 for all standard game inventories. Steam Community items (appid 753) also use context ID 6 for some item types.
Private profiles: Inventory must be set to public, or you must be authenticated as the owner.
