Steam Community Inventory Skill

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

Setup

1. 1. 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

1. 2. 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

1. 3. Set environment variables:

CODEBLOCK0

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.

CODEBLOCK1

Get CS2 inventory

CODEBLOCK2

Get a summary of items (names and quantities)

CODEBLOCK3

Get item details (asset IDs mapped to descriptions)

CODEBLOCK4

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:

CODEBLOCK5

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
INLINECODE12	Array of items with appid, contextid, assetid, classid, instanceid, INLINECODE18
INLINECODE19

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.
