Tái sử dụng bot Binance Futures sẵn có của bạn

Hầu hết các SDK Binance Futures đều chấp nhận base URL tùy chỉnh. Đây là toàn bộ thay đổi mà một bot Python thông thường cần:

# before — trading on real Binance
from binance.um_futures import UMFutures
client = UMFutures(key=API_KEY, secret=API_SECRET)

# after — trading on a BuyCrypt user's demo
from binance.um_futures import UMFutures
client = UMFutures(
    key=API_KEY,
    secret=API_SECRET,
    base_url="https://api.buycrypt.com/fapi",   # <- the only line that changes
)

# everything below is identical to your existing code
client.new_order(symbol="BTCUSDT", side="BUY", type="MARKET", quantity=0.01)
client.account()
client.cancel_open_orders(symbol="BTCUSDT")

CCXT, python-binance, go-binance của Go, node-binance-api của JS — tất cả đều hoạt động như nhau. Các bot dùng requests.get(...).headers["X-MBX-APIKEY"] = key đơn giản cũng chạy được; quy tắc ký HMAC giống hệt từng byte.

Cách chúng tôi gửi API key đến hệ thống của bạn

Khi một người dùng BuyCrypt đăng ký theo bot của bạn, chúng tôi tạo API key + secret riêng cho từng người dùng ở phía server và POST chúng đến webhook URL đã đăng ký của bạn. Secret không bao giờ được trả về cho người dùng — nó chỉ được gửi đến bạn, qua HTTPS, có chữ ký.

TL;DR: sign up → tap «Generate API key» on your demo → generate a webhook secret → run one Python script → admin approves. ~5 minutes.

Step 1 — Sign up

Open buycrypt.com/terminal (or the mobile app). Sign in via Google or phone. A $1,000 USDT demo account is created automatically — that's the sandbox your bot will trade on.

Step 2 — Generate your trading API key (in the app)

In the app: Profile → API Keys → tap your demo account → «Bot API keys» → Generate. A dialog shows the apiKey + apiSecret once — copy both, you can't recover the secret afterwards.

# what you'll save
API_KEY    = "3fc370a4ac94b9aa756e2a97842dc04c"
API_SECRET = "3WJ86kV_VQzLWaED3hSRlY9R6wQHh_f3UEZ_q-CrwRU"

Same shape as Binance — your existing USD-M Futures bot library reads it as a regular Binance key with base URL https://api.buycrypt.com/fapi.

Step 3 — Generate your webhook signing secret

A second secret, separate from API_SECRET. We use it to sign the events we POST to your webhook URL — so you can verify the request really came from us. You generate it on your side; we encrypt-store it but never reveal back:

# any of these works — pick one. Save the output.
$ openssl rand -hex 32                          # macOS / Linux
$ python3 -c "import secrets; print(secrets.token_hex(32))"   # cross-platform

# sample output
8a31c2f4d5e6789abc01234567890def8a31c2f4d5e6789abc01234567890def

Step 4 — Register the bot (one signed POST)

Drop your three secrets into one signed POST. Save this as register_bot.py and run it once. Works on any OS with Python 3.10+ and pip install requests:

import hmac, hashlib, time, urllib.parse, requests

# ─── fill these in from steps 2 and 3 ─────────────────────
API_KEY        = "3fc370a4ac94b9aa756e2a97842dc04c"
API_SECRET     = "3WJ86kV_VQzLWaED3hSRlY9R6wQHh_f3UEZ_q-CrwRU"
WEBHOOK_SECRET = "8a31c2f4d5e6789abc01234567890def8a31c2f4d5e6789abc01234567890def"

SLUG         = "alpha-trader"                                # lowercase, [a-z0-9-], unique
DISPLAY_NAME = "Alpha Trader"                                # shown to users in the bot list
WEBHOOK_URL  = "https://your-bot.example.com/buycrypt/hook"   # MUST be HTTPS, public
# ──────────────────────────────────────────────────────────

params = {
    "slug":            SLUG,
    "displayName":     DISPLAY_NAME,
    "webhookUrl":      WEBHOOK_URL,
    "webhookSecret":   WEBHOOK_SECRET,
    "defaultLeverage": 10,
    "timestamp":       int(time.time() * 1000),
}
qs  = urllib.parse.urlencode(params)
sig = hmac.new(API_SECRET.encode(), qs.encode(), hashlib.sha256).hexdigest()

r = requests.post(
    "https://api.buycrypt.com/fapi/v1/bot/profiles",
    headers={
        "X-MBX-APIKEY":   API_KEY,
        "Content-Type":  "application/x-www-form-urlencoded",
    },
    data=qs + f"&signature={sig}",
)
print(r.status_code, r.json())

Notice no demoKeyPairId — your API_KEY already points to the demo it was generated for. Need to register against a different demo? Generate a separate API key for it (step 2 again).

Expected output:

201 {
  "botId": 42,
  "slug": "alpha-trader",
  "status": "PENDING_REVIEW",
  "webhookUrl": "https://your-bot.example.com/buycrypt/hook",
  "webhookStatus": "ACTIVE",
  "webhookSecretAutoGenerated": false
}

Common errors:

{"code":-2010, "msg":"Slug already in use."}                # pick another slug
{"code":-1102, "msg":"webhookSecret must be at least 32..."}  # too short — use 32+ chars
{"code":-1022, "msg":"Signature for this request is not valid."}  # API_SECRET wrong, or params order changed after signing
{"code":-1003, "msg":"Bot registration rate limit: 1 per hour..."}  # wait it out

Step 5 — Wait for approve, then receive events

Bot lands in PENDING_REVIEW. Our admin sees your request immediately and approves it. To check status anytime:

import hmac, hashlib, time, urllib.parse, requests

API_KEY    = "3fc370a4..."
API_SECRET = "3WJ86kV..."

qs  = urllib.parse.urlencode({"timestamp": int(time.time() * 1000)})
sig = hmac.new(API_SECRET.encode(), qs.encode(), hashlib.sha256).hexdigest()
r = requests.get(
    f"https://api.buycrypt.com/fapi/v1/bot/profiles?{qs}&signature={sig}",
    headers={"X-MBX-APIKEY": API_KEY},
)
print(r.json())   # [{"botId":42, "status":"ACTIVE", ...}] when approved

Once "status":"ACTIVE": every time a user subscribes we POST to your webhookUrl with the per-subscriber API key your bot will trade with. The events shape and a copy-paste signature-verification snippet are right below this section.

Lost your webhook secret? Pick a new one and rotate (same signing pattern as registration):

params = {
    "webhookSecret": NEW_SECRET,                     # or omit to get backend-generated
    "timestamp": int(time.time() * 1000),
}
qs  = urllib.parse.urlencode(params)
sig = hmac.new(API_SECRET.encode(), qs.encode(), hashlib.sha256).hexdigest()
requests.post(
    "https://api.buycrypt.com/fapi/v1/bot/profiles/42/webhook/rotate-secret",
    headers={"X-MBX-APIKEY": API_KEY,
             "Content-Type": "application/x-www-form-urlencoded"},
    data=qs + f"&signature={sig}",
)

Old secret invalid the second the new one saves. Rate limit: 10 rotations/hour per bot.

  }
}

Verify the signature (constant-time)

Use the raw request body bytes — DO NOT parse JSON first and re-serialize, you'll lose key order and signatures will diverge. Always compare in constant time.

# Python (FastAPI / Flask)
import hmac, hashlib, time

WEBHOOK_SECRET = "whsec_aGVsbG8gd29ybGQ_..."   # whsec_…43 chars

def verify(headers, body_bytes):
    sig = headers["X-BuyCrypt-Signature"]
    ts  = int(headers["X-BuyCrypt-Timestamp"])

    # anti-replay: reject if too old
    if abs(time.time() * 1000 - ts) > 5 * 60 * 1000:
        return False

    payload = f"{ts}.".encode() + body_bytes
    expected = hmac.new(WEBHOOK_SECRET.encode(), payload, hashlib.sha256).hexdigest()

    return hmac.compare_digest(expected, sig)

// Node.js / Express — read RAW body, not parsed JSON
const crypto = require('crypto');
const SECRET = 'whsec_aGVsbG8gd29ybGQ_...';

app.post('/buycrypt/hook',
  express.raw({ type: 'application/json' }),   // raw, not json()!
  (req, res) => {
    const sig = req.headers['x-buycrypt-signature'];
    const ts  = parseInt(req.headers['x-buycrypt-timestamp'], 10);

    if (Math.abs(Date.now() - ts) > 5 * 60 * 1000) return res.status(401).end();

    const expected = crypto.createHmac('sha256', SECRET)
      .update(`${ts}.`).update(req.body).digest('hex');

    if (!crypto.timingSafeEqual(Buffer.from(expected), Buffer.from(sig))) {
      return res.status(401).end();
    }
    // req.body is a Buffer here — JSON.parse(req.body.toString('utf8'))
    res.sendStatus(200);
});
