Game Market Skill

Query YY game trading marketplace listings directly in chat. Browse by game → category → listings → paginate. When the user wants to actually buy or sell, confirm then open the browser.

No login required. The API uses a front-end signature (MD5-based) that is self-contained.

When to Activate

Activate when the user:

• Runs /game-market manually
• Mentions game trading keywords: game account, buy/sell account, boosting, coaching, game currency, game items
• Mentions specific game names: 王者荣耀, 英雄联盟, 三角洲行动, 和平精英, 穿越火线, 无畏契约, 绝地求生, 崩坏, 原神, CSGO
• Mentions YY marketplace: YY交易, YY商城, mall.yy.com

Workflow

Step 1 — Intent Recognition

Extract from user input:

• Game name → categoryId
• Sub-category → subCategoryId

If intent is unclear (game mentioned but no category, or vice versa), go to Step 2.

Step 2 — Category Selection (when intent is unclear)

Run this Python snippet to fetch and display categories:

import hashlib, uuid, time, requests

APPID  = "market_app"
SECRET = "ixlOJVDwdOm5rGdudhEywwK6"
HDID   = "38e6a82f5f724517d6cbe82cde56e846690afcb0"
BASE   = "https://gamemarket.yy.com"

def sign(uri):
    nonce = str(uuid.uuid4())
    ts    = str(int(time.time() * 1000))
    raw   = f"appId={APPID}&nonce={nonce}&timestamp={ts}&uri={uri}&secret={SECRET}"
    sig   = hashlib.md5(raw.encode()).hexdigest()
    return {
        "accept": "application/json, text/plain, */*",
        "origin": "https://mall.yy.com",
        "referer": "https://mall.yy.com/",
        "user-agent": "Mozilla/5.0",
        "x-appid": APPID, "x-nonce": nonce, "x-timestamp": ts, "x-signature": sig,
    }

uri  = "/category/queryShowCategories"
resp = requests.get(BASE + uri, params={"sid": "", "hdid": HDID}, headers=sign(uri), timeout=15)
cats = resp.json()["data"]

for c in cats:
    subs = ", ".join(s["name"] for s in c.get("subCategories", []))
    print(f"  {c['id']:>2}. {c['name']}  ({subs})")

Present the list to the user and ask them to choose game and sub-category.

Step 3 — Query Listings

Run this Python snippet with the resolved category_id and sub_category_id:

import hashlib, uuid, time, requests

APPID  = "market_app"
SECRET = "ixlOJVDwdOm5rGdudhEywwK6"
HDID   = "38e6a82f5f724517d6cbe82cde56e846690afcb0"
BASE   = "https://gamemarket.yy.com"

def sign(uri):
    nonce = str(uuid.uuid4())
    ts    = str(int(time.time() * 1000))
    raw   = f"appId={APPID}&nonce={nonce}&timestamp={ts}&uri={uri}&secret={SECRET}"
    sig   = hashlib.md5(raw.encode()).hexdigest()
    return {
        "accept": "application/json, text/plain, */*",
        "origin": "https://mall.yy.com",
        "referer": "https://mall.yy.com/",
        "user-agent": "Mozilla/5.0",
        "x-appid": APPID, "x-nonce": nonce, "x-timestamp": ts, "x-signature": sig,
    }

# ---- Set these before running ----
category_id     = 5    # None = all games
sub_category_id = 5
page_num        = 1
# ----------------------------------

uri    = "/goods/v2/search"
params = {
    "pageNum": str(page_num), "pageSize": "20",
    "requestSource": "HOME", "withRegionServer": "true",
    "hdid": HDID, "subCategoryId": str(sub_category_id),
    "searchDistChannelGoods": "false",
}
if category_id is not None:
    params["categoryId"] = str(category_id)

resp   = requests.get(BASE + uri, params=params, headers=sign(uri), timeout=15)
result = resp.json()["data"]
goods  = result.get("goodsList", [])
total  = result.get("totalCount", 0)

print(f"Total: {total} listings  |  Page {page_num}\n")
for i, g in enumerate(goods, 1):
    price  = g["salePrice"] / 100
    name   = g["goodsName"].replace("\r\n", " ").replace("\n", " ")[:80]
    labels = "  ".join(lb["labelName"] for lb in g.get("goodsLabels", []))
    gid    = g["goodsId"]
    cat    = g.get("categoryName", "")
    sub    = g.get("subCategoryName", "")
    url    = f"https://mall.yy.com/?pageId=20000#/shop/detail/{gid}"
    print(f"[{i:02d}] ¥{price:.0f}  {cat} · {sub}")
    print(f"     {name}")
    if labels:
        print(f"     【{labels}】")
    print(f"     🔗 {url}\n")

Step 4 — Follow-up Interaction

After displaying results, keep listening:

Buy / Sell Flow

When the user expresses intent to buy or sell:

1. Reply with confirmation prompt:

   To buy or sell, you'll need to use the YY marketplace website. Open it now?

2. If user confirms, run:

# Open YY marketplace homepage
open "https://mall.yy.com/?pageId=20000"

If the user was interested in a specific item, open its detail page instead:

open "https://mall.yy.com/?pageId=20000#/shop/detail/{goodsId}"

Error Handling

Out of Scope

• Login / authentication (not needed for queries)
• Placing orders or payments (redirect to website instead)
• Price sorting / filtering (future iteration)
• Favorites / comparison

Examples

User: show me 王者荣耀 accounts
→ Queries categoryId=5, subCategoryId=5, displays 20 listings

User: I want to look at boosting services
→ Game unclear → shows game list for selection

User: next page
→ Increments to page 2, same category

User: open item 3
→ Opens https://mall.yy.com/?pageId=20000#/shop/detail/{goodsId}

User: I want to buy this
→ "To buy, you'll need the YY website. Open it now?"
→ Confirmed → open "https://mall.yy.com/?pageId=20000#/shop/detail/{goodsId}"

User: I want to sell my account
→ "To sell, you'll need the YY website. Open it now?"
→ Confirmed → open "https://mall.yy.com/?pageId=20000"
