Binance API Integration & Protocol Analysis Services

Deliverables

• OpenAPI / Swagger interface specifications
• Protocol and authorization flow analysis (including notes on how authorization is implemented)
• Runnable backend code (Node.js / Python), including authentication, market data, order and positions sync modules
• Automated tests, Postman collections and sample SDK
• Compliance recommendations (KYC, data retention, regional regulatory alignment)

Interface Example: Account Balance Query (pseudo-code / secure mode)

// Server-side API Key + Secret signing (pseudo)
POST /api/v1/account/balances
Content-Type: application/json
API-KEY: xxxxx
X-SIGN: HMAC_SHA256(nonce + body, API_SECRET)

{ "user_id": "cust_1234", "include_zero": false }

Response:
{
  "status": "ok",
  "balances": [
    {"symbol":"BTC","available":"0.01234","locked":"0.00000"},
    {"symbol":"USDT","available":"1200.50","locked":"0.00"}
  ],
  "timestamp": 1699999999
}

Interface Example: Market Data Subscription (WebSocket)

// WebSocket subscription example (pseudo)
ws.connect('wss://api.exchange.example/ws')
ws.send(JSON.stringify({"op":"subscribe","channel":"ticker","symbol":"BTCUSDT"}))
// receive: {"ch":"ticker","symbol":"BTCUSDT","price":"60321.12","ts":1699999999}

Core Advantages

• Compliance-first: only integrate based on authorized APIs or client-provided credentials, with compliance auditing guidance
• Production-ready: deployable APIs, SDKs, tests and monitoring configurations
• Multi-protocol coverage: REST / WebSocket / gRPC / JSON-RPC (on-chain)
• Security practices: signing, key rotation, rate limiting and least privilege policy
• Cross-region experience: supports global exchanges and local regulatory requirements

Typical Integration Workflow (Brief)

1. Requirements: target interfaces (market data / orders / copies / reports) and compliance boundaries
2. Protocol & authorization analysis (2-4 days) — keys, signing, callbacks, rate limits
3. Development & testing (3-10 days) — REST, WebSocket, SDK, tests
4. Security review & compliance guidance (including logging strategy)
5. Delivery & training: source code, documentation, test suites and operations guide

API Quick Start Guide (for engineers)

1. Preparation: obtain API Key, Secret and callback whitelist IP from exchange/client
2. Signing: implement HMAC-SHA256 (or as required), include timestamp and nonce to prevent replay
3. Rate limiting: implement local request queue and rate limiter; handle 429 and backoff retries
4. Security: store keys in secure key management (KMS), support rotation and least privilege
5. Monitoring: report latency, success rate, anomalous trades and audit logs; automatic alerts

Node.js quick commands (pseudo):

// Node.js pseudo: query balance
const resp = await fetch('https://api.exchange.example/v1/account/balances',{
  method:'POST',
  headers:{'API-KEY':KEY,'X-SIGN':sign(payload, SECRET),'Content-Type':'application/json'},
  body:JSON.stringify(payload)
});
