# Steam Community Inventory Skill

Retrieve and browse a Steam user's inventory, and send/manage trade offers on steamcommunity.com.

## Setup

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](https://steamid.io) and paste your profile URL to get your SteamID64

2. Get your **Steam Web API key**:
   - Go to [https://steamcommunity.com/dev/apikey](https://steamcommunity.com/dev/apikey)
   - Register a domain name (any value works, e.g., `localhost`)
   - Copy the API key shown on the page

3. Get your **Steam session cookies** (required for trade offers and bypassing inventory rate limits):
   - Log in to [steamcommunity.com](https://steamcommunity.com) in your browser
   - Open Developer Tools (F12) > Application tab > Cookies > `https://steamcommunity.com`
   - Copy the value of the `steamLoginSecure` cookie
   - Copy the value of the `sessionid` cookie

4. Set environment variables:
   ```bash
   export STEAM_ID="your-steamid64"
   export STEAM_API_KEY="your-api-key"
   export STEAM_COOKIES="steamLoginSecure=your-cookie-value"
   export STEAM_SESSION_ID="your-sessionid-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

|------|--------|
| CS2 / CS:GO | 730 |
| Team Fortress 2 | 440 |
| Dota 2 | 570 |
| Rust | 252490 |

### 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.

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