Steam & PC Gaming Companion#

A complete Steam Web API integration skill. Manages your library, tracks achievements, monitors wishlist sales, recommends what to play next, and looks up any game — all from natural language.

---

Setup#

Step 1: Get Your Steam API Key (required, 30 seconds)#

1. Go to https://steamcommunity.com/dev/apikey
2. Sign in with your Steam account
3. Enter any domain name (e.g. localhost) — it doesn't matter for personal use
4. Click Register and copy the key
5. Set it: STEAM_API_KEY=<your-key>

Step 2: Get Your 64-bit Steam ID (required, 15 seconds)#

Your Steam ID is NOT your vanity URL or display name. It's a 17-digit number.

1. Go to https://steamid.io
2. Paste your Steam profile URL (e.g. https://steamcommunity.com/id/yourname)
3. Copy the steamID64 value (looks like 76561198012345678)
4. Set it: STEAM_ID=<your-steam-id-64>

Step 3: Get IGDB Credentials (optional, 2 minutes)#

IGDB provides richer game metadata (ratings, genres, descriptions) than the Steam store API. It's free via Twitch.

1. Go to https://dev.twitch.tv/console/apps and log in with your Twitch account (create one if needed)

2. Click Register Your Application

3. Name: anything (e.g. steam-companion), OAuth Redirect: http://localhost, Category: Application Integration

4. Click Manage on your new app, copy the Client ID

5. Generate a Client Secret and copy it

6. Get an access token by running: text

   curl -X POST 'https://id.twitch.tv/oauth2/token' \
     -d 'client_id=YOUR_CLIENT_ID&client_secret=YOUR_CLIENT_SECRET&grant_type=client_credentials'
   
   

7. Copy the access_token from the response

8. Set both: text

   IGDB_CLIENT_ID=<your-client-id>
   IGDB_ACCESS_TOKEN=<your-access-token>
   
   

Note: IGDB tokens expire after ~60 days. If game lookups start failing with 401, regenerate the token using step 6.

Step 4: Verify Setup#

Tell the agent: "verify my steam setup" — it will confirm your credentials work and show your account name and library size.

Feature 1: Library Overview + Backlog Manager#

API Call#

text

GET https://api.steampowered.com/IPlayerService/GetOwnedGames/v1/

Query parameters:

ParameterValuekey``{STEAM_API_KEY}``steamid``{STEAM_ID}``include_appinfo``1``include_played_free_games``1``format``json

Response Fields Used#

json

{
  "response": {
    "game_count": 247,
    "games": [
      {
        "appid": 570,
        "name": "Dota 2",
        "playtime_forever": 14523,

Feature 2: Play Recommender#

Prerequisites#

Fetch the full library using the same API call as Feature 1.

Interaction Flow#

1. Ask the user two questions (or extract from their message if already stated):

   • Mood: chill / intense / story-driven / competitive
   • Time available: under 1 hour / 1-2 hours / all night (3+ hours)

2. Filter the user's library to games with playtime_forever < 60 (unplayed) OR 60 <= playtime_forever < 300 (abandoned — gave it a short try).

3. For each candidate game, look up genre data. Use one of these methods:

   • If IGDB credentials exist: POST to https://api.igdb.com/v4/games with body search "{game_name}"; fields genres.name, themes.name, total_rating; limit 1; and headers Client-ID: {IGDB_CLIENT_ID}, Authorization: Bearer {IGDB_ACCESS_TOKEN}
   • If no IGDB: GET https://store.steampowered.com/api/appdetails?appids={appid} and extract data.genres[].description and data.short_description

4. Match games to mood using these genre mappings:

MoodMatching Genres / ThemesChillSimulation, Puzzle, Casual, Farming, Sandbox, Walking Simulator, Indie (non-horror)IntenseAction, Shooter, Roguelike, Roguelite, Survival Horror, Souls-like, Bullet HellStory-drivenRPG, Adventure, Visual Novel, Interactive Fiction, Narrative, Point & ClickCompetitiveMultiplayer, PvP, Fighting, Sports, Racing, Battle Royale, MOBA

1. Match games to time available:

Time SlotRuleUnder 1 hourPrefer games with short play sessions — roguelites, puzzle games, platformers, arcade. Avoid open-world RPGs or grand strategy.1-2 hoursAny genre works. Prefer games with moderate session lengths.All nightPrefer RPGs, open-world, strategy, survival, sandbox — games that reward long sessions.

1. Select the top 3 matches. If fewer than 3 match, relax the playtime filter to include games up to 600 minutes.

Response Format#

text

🎯 Play Recommendations — {mood}, {time_available}

1. 🎮 {game_name}
   Genre: {genres}
   Why: {1-2 sentence reason based on mood + time fit}
   Playtime so far: {minutes} min

2. 🎮 {game_name}

   Why: {reason}
   Playtime so far: {minutes} min

3. 🎮 {game_name}
   Genre: {genres}
   Why: {reason}
   Playtime so far: {minutes} min

💡 None of these click? Tell me more about what you're in the mood for.

If no games match at all:

text

😅 Couldn't find a great match in your unplayed library for "{mood}" + "{time}".

Your unplayed games are mostly: {top 3 genres in unplayed list}.

Want me to check your full library instead, or look up something new?

Feature 3: Wishlist Sale Monitor#

API Call#

text

GET https://store.steampowered.com/wishlist/profiles/{STEAM_ID}/wishlistdata/

No API key needed — uses the Steam store API directly. Requires the user's wishlist to be public.

Note: This endpoint may paginate. If the response contains exactly 50 items, make additional requests:

text

GET https://store.steampowered.com/wishlist/profiles/{STEAM_ID}/wishlistdata/?p=1
GET https://store.steampowered.com/wishlist/profiles/{STEAM_ID}/wishlistdata/?p=2

Continue incrementing p until the response is empty or contains fewer than 50 items. Page 0 is the default.

Response Fields Used#

Each entry is keyed by appid:

json

{
  "730": {
    "name": "Counter-Strike 2",
    "capsule": "url-to-image",
    "review_score": 7,
    "review_desc": "Very Positive",
    "reviews_total": "7,456,123",
    "reviews_percent": 86,
    "release_date": "1694649600",
    "release_string": "Sep 27, 2023",
    "priority": 0,
    "added": 1680000000,
    "background": "url",
    "rank": 14,
    "tags": ["FPS", "Shooter"],
    "is_free_game": false,
    "subs": [
      {
        "id": 54029,
        "discount_block": "<div ...>-75%</div>",
        "discount_pct": 75,
        "price": "749"
      }
    ]
  }
}

Logic Rules#

1. Iterate over all wishlist entries
2. For each entry, check subs array. A game is on sale if any sub has discount_pct > 0
3. The price field is the current (discounted) price in cents (e.g. 749 = $7.49). If price is a string, parse it as an integer first.
4. Calculate original price: original_price = price / (1 - discount_pct / 100)
5. Sort results by discount_pct descending (biggest discounts first)

Response Format#

If sales found:

text

🏷️ Wishlist Sales — {count} game(s) on sale!

{for each discounted game, sorted by discount_pct desc:}
🔥 {name} — {discount_pct}% OFF
   💰 ${sale_price} (was ${original_price})
   ⭐ {review_desc} ({reviews_percent}% positive)
   🔗 https://store.steampowered.com/app/{appid}
{end}

💡 Prices are current as of this check. Steam sales change without notice.

If no sales:

text

🏷️ Wishlist Sales

No games on your wishlist are currently discounted.

📋 You have {total_wishlist_count} games wishlisted.
Top 3 by priority:
  1. {name} — {review_desc}
  2. {name} — {review_desc}
  3. {name} — {review_desc}

💡 Major Steam sales happen in June (Summer Sale) and December (Winter Sale).

If wishlist is empty or inaccessible:

text

⚠️ Couldn't access your wishlist.

This usually means your wishlist is set to private. To fix:
1. Go to your Steam profile → Edit Profile → Privacy Settings
2. Set "Game details" to Public
3. Try again

If it's already public, Steam's wishlist API may be temporarily down. Try again in a few minutes.

Feature 4: Achievement Tracker#

Step 1: Get Player Achievements#

text

GET https://api.steampowered.com/ISteamUserStats/GetPlayerAchievements/v1/

Query parameters:

ParameterValuekey``{STEAM_API_KEY}``steamid``{STEAM_ID}``appid``{appid}``l``english

Response fields:

json

{
  "playerstats": {
    "steamID": "76561198012345678",
    "gameName": "Hades",
    "success": true,
    "achievements": [
      {
        "apiname": "AchUnlockAll",
        "achieved": 1,
        "unlocktime": 1695000000
      }
    ]
  }
}

• achieved: 1 = unlocked, 0 = locked
• unlocktime: Unix timestamp (0 if locked)

Step 2: Get Achievement Schema (for human-readable names + descriptions)#

text

GET https://api.steampowered.com/ISteamUserStats/GetSchemaForGame/v2/

Query parameters:

ParameterValuekey``{STEAM_API_KEY}``appid``{appid}``l``english

Response fields:

json

{
  "game": {
    "gameName": "Hades",
    "availableGameStats": {
      "achievements": [
        {
          "name": "AchUnlockAll",
          "defaultvalue": 0,
          "displayName": "Everything in its Place",
          "hidden": 0,
          "description": "Unlock all other achievements.",
          "icon": "url-to-achieved-icon",
          "icongray": "url-to-locked-icon"
        }
      ]
    }
  }
}

Step 3: Resolve Game Name to AppID#

If the user says a game name instead of an AppID, resolve it:

text

GET https://api.steampowered.com/ISteamApps/GetAppList/v2/

This returns ALL Steam apps (~180,000). To avoid fetching this every time:

1. First try the store search API: GET https://store.steampowered.com/api/storesearch/?term={game_name}&l=english&cc=US
2. Use the first result's id as the appid
3. If no results, tell the user the game wasn't found and ask them to check the name

Logic Rules#

1. Fetch both player achievements and schema for the given appid
2. Match achievements by apiname (player data) to name (schema data)
3. Replace API names with displayName from the schema
4. Sort unlocked achievements by unlocktime descending (most recent first)
5. Calculate: unlocked_count, total_count, completion_pct
6. Build a visual progress bar: use █ for filled and ░ for empty, 20 characters wide
7. Show the 5 most recently unlocked achievements
8. Show up to 5 locked achievements (non-hidden ones only; for hidden: 1, show as "🔒 Hidden Achievement")

Response Format#

text

🏆 Achievements — {game_name}

Progress: {unlocked_count}/{total_count} ({completion_pct}%)
[████████████░░░░░░░░] {completion_pct}%

🔓 Recently Unlocked
{for each of the 5 most recent, by unlocktime desc:}
  ✅ {displayName} — {description}
     Unlocked: {formatted_date}
{end}

🔒 Up Next ({remaining_count} remaining)
{for up to 5 non-hidden locked achievements:}
  ⬜ {displayName} — {description}
{end}
{if hidden locked achievements exist:}
  🔒 +{hidden_count} hidden achievement(s)
{end}

{if completion_pct == 100:}
🎉 Completionist! You've unlocked every achievement in {game_name}!
{end}

Error: Game Has No Achievements#

If GetSchemaForGame returns no achievements array or it's empty:

text

ℹ️ {game_name} doesn't have Steam achievements.

Error: Achievement Data Private#

If GetPlayerAchievements returns success: false:

text

⚠️ Can't access achievement data for {game_name}.

This usually means your game details are set to private. To fix:
1. Go to Steam → Profile → Edit Profile → Privacy Settings
2. Set "Game details" to Public
3. Try again

Feature 5: Most Played Rankings#

API Call#

Same as Feature 1 — IPlayerService/GetOwnedGames/v1 with include_appinfo=1.

Logic Rules#

1. Sort all games by playtime_forever descending
2. Take the top 10
3. Convert minutes to hours and minutes: hours = playtime_forever // 60, minutes = playtime_forever % 60
4. Calculate total lifetime hours across ALL games: sum(playtime_forever for all games) / 60
5. If playtime_2weeks exists on any game, also show "Recently Active" section

Response Format#

text

📊 Total Lifetime Gaming: {total_hours} hours across {game_count} games
   That's {total_days} days of gaming!

{if any game has playtime_2weeks:}
🕹️ Active This Week
{for each game with playtime_2weeks > 0, sorted desc:}
  • {name} — {hours}h {minutes}m in the last 2 weeks
{end}
{end}

To fix:
1. Go to https://steamcommunity.com/dev/apikey
2. Make sure you're logged into the correct Steam account
3. If you see a key, copy it exactly (no spaces)
4. If you don't see a key, register a new one with any domain
5. Update your STEAM_API_KEY env var

Failure — bad Steam ID:

If players array is empty:

text

❌ Setup Failed — Steam ID Not Found

No account found for Steam ID: {STEAM_ID}

To fix:
1. Go to https://steamid.io
2. Paste your Steam profile URL
3. Copy the steamID64 (17-digit number like 76561198012345678)
4. Update your STEAM_ID env var

Common mistakes:
• Using your vanity URL name instead of the 64-bit ID
• Using a 32-bit Steam ID (shorter number) instead of 64-bit
• Extra spaces or characters in the value

Failure — missing env vars:

text

❌ Setup Failed — Missing Credentials

Error Handling (Global)#

Private Profile#

Detection: IPlayerService/GetOwnedGames/v1 returns {"response": {}} (empty, no game_count or games key).

Response:

text

🔒 Your Steam profile or game details are set to private.

To use this skill, your profile needs to be public:
1. Open Steam → click your name → Profile
2. Click Edit Profile → Privacy Settings
3. Set "My profile" to Public
4. Set "Game details" to Public
5. Wait 1-2 minutes for Steam's cache to update
6. Try again

Note: You can set it back to private after you're done.

API Rate Limiting#

Steam's Web API has a rate limit of approximately 100,000 calls per day and 1 request per second per key. In practice, you will not hit this unless you're scripting bulk requests.

If you receive HTTP 429 or 503:

text

⏳ Steam's API is temporarily rate-limiting requests. Wait a minute and try again.

Network / Server Errors#

If any API call returns HTTP 500, 502, 503, or times out:

text

⚠️ Steam's API returned an error ({status_code}). This is on Steam's end, not yours.

Try again in a minute. If it persists, check https://steamstat.us for outages.

Missing Environment Variables#

Before making any API call, check that the required env vars are set. If missing:

text

⚠️ Missing required configuration.

{if STEAM_API_KEY not set:}
• STEAM_API_KEY — Get one at https://steamcommunity.com/dev/apikey
{end}
{if STEAM_ID not set:}
• STEAM_ID — Find yours at https://steamid.io
{end}

Run "verify my steam setup" after setting them.

IGDB Token Expired#

IGDB access tokens expire after approximately 60 days. If any IGDB API call returns HTTP 401:

text

⚠️ Your IGDB access token has expired.

To regenerate it:
1. Run this command (replace with your credentials):

Falling back to Steam store API for this lookup.

After showing this message, fall back to Steam store API (Method B) for the current request so the user still gets a result.

Store API Region Issues#

store.steampowered.com/api/appdetails may return different prices based on region. Prices shown are for the US store by default. Add &cc=US to force USD, or &cc={country_code} if the user requests a different region.

Example Conversations#

Example 1: Library Check#

User: How many games do I own on Steam?

Agent: Calls IPlayerService/GetOwnedGames/v1 → gets library → categorizes → responds with full library overview showing total count, backlog breakdown, and the unplayed/abandoned lists.

Example 2: Play Recommendation#

User: I've got about 2 hours tonight and want something chill. What should I play?

Agent: Fetches library → filters unplayed/abandoned games → looks up genres for each via IGDB or Steam store → matches to "chill" + "1-2 hours" → picks 3 best matches → responds with names, genres, and personalized reasons.

Example 3: Wishlist Check#

User: Any games on my wishlist on sale?

Agent: Calls wishlist API → checks all subs for discount_pct > 0 → calculates original prices → sorts by discount → responds with formatted sale list or "no sales" message with upcoming sale dates.

Example 4: Achievement Progress#

User: Show my achievements for Hades

Agent: Searches store for "Hades" → gets appid 1145360 → calls GetPlayerAchievements and GetSchemaForGame → matches by apiname → calculates completion → builds progress bar → shows recent unlocks and remaining achievements.

Example 5: Quick Stats#

User: What are my most played games?

Agent: Fetches library → sorts by playtime_forever desc → takes top 10 → formats table with hours/minutes → calculates total lifetime hours → shows recently active games if any.

Example 6: Game Lookup#

User: Tell me about Baldur's Gate 3

Agent: If IGDB configured, POSTs search query → gets name, summary, rating, genres, developer, release date. If not, searches Steam store → gets appdetails. Also checks if user owns it and shows playtime.

Notes for Agent Implementors#

• All Steam Web API calls use HTTPS GET with query parameters. No POST requests needed for Steam.
• IGDB uses POST with a plain-text body in Apicalypse query language. Content-Type must be text/plain.
• The wishlist endpoint ( store.steampowered.com) does not require an API key but does require the wishlist to be public.
• Steam's playtime_forever is always in minutes. Always convert to hours/minutes for display.
• Unix timestamps from Steam and IGDB should be formatted as human-readable dates (e.g., "Sep 17, 2020").
• The store search API ( storesearch) is the fastest way to resolve a game name to an appid. Do not fetch the full app list unless store search fails.
• When making multiple API calls for a single feature (e.g., achievements need 2 calls), make them concurrently where possible.
• IGDB access tokens expire. If a 401 is returned, tell the user to regenerate the token.
