如何将你的机器人接入 BuyCrypt

复用你现有的 Binance 合约机器人

大多数 Binance 合约 SDK 都支持自定义基础 URL。以下是一个典型 Python 机器人所需的全部改动：

# 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 的 go-binance、JS 的 node-binance-api——都以相同方式工作。纯粹使用 requests.get(...).headers["X-MBX-APIKEY"] = key 的机器人同样可用；HMAC 签名规则完全一致（字节级相同）。

我们如何将 API 密钥送达你的系统

当 BuyCrypt 用户订阅你的机器人时，我们会在服务端为该用户生成专属的 API key + secret，并通过 HTTPS 以签名方式 POST 到你注册的 webhook URL。密钥永远不会返回给用户——只会发送给你。

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.

  }
}

  "event":      "secret.regenerated",
  "deliveryId": "…",
  "timestamp":  …,
  "data": {
    "subscriptionId":       42,

    "oldSecretValidUntil":  "2026-04-26T18:00:00Z"
  }
}

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);
});
