Parameter Validation Rules

Before sending a request, validate parameters client-side to avoid unnecessary API errors:

• symbol: Must match ^[A-Z0-9]+-[A-Z]+$; max 20 characters (e.g., BTC-USDT)
• quantity: Must be a positive number (> 0); precision depends on the symbol's lot-size filter

• price: When provided, must be a positive number (> 0)
• stopPrice: When provided, must be a positive number (> 0)
• newClientOrderId: 1–40 characters; avoid special characters that could be interpreted as injection
• recvWindow: Integer, 1–5000 ms; keep as small as possible (see Replay Protection)
• timestamp: Unix time in milliseconds; must be within recvWindow of server time

Quick Start

CONSTRAINT: You MUST copy the fetchSigned function below verbatim when generating code. Do NOT rewrite the signing, request, or JSON parsing logic. Only modify: (1) BASE URL entries for custom environments, (2) business parameters passed to fetchSigned. For the full client with URL-encoding and JSON body support, see references/authentication.md.

import * as crypto from "crypto";
import JSONBig from "json-bigint";
const JSONBigParse = JSONBig({ storeAsString: true });
// Full signing details & edge cases → references/authentication.md
// Domain priority: .com is mandatory primary; .pro is fallback for network/timeout errors ONLY.
const BASE = {
  "prod-live": ["https://open-api.bingx.com", "https://open-api.bingx.pro"],
  "prod-vst":  ["https://open-api-vst.bingx.com", "https://open-api-vst.bingx.pro"],
};
function isNetworkOrTimeout(e: unknown): boolean {
  if (e instanceof TypeError) return true;
  if (e instanceof DOMException && e.name === "AbortError") return true;
  if (e instanceof Error && e.name === "TimeoutError") return true;
  return false;
}
async function fetchSigned(env: string, apiKey: string, secretKey: string,
  method: "GET" | "POST" | "DELETE", path: string, params: Record<string, unknown> = {}
) {
  const urls = BASE[env] ?? BASE["prod-live"];
  const all = { ...params, timestamp: Date.now() };
  const qs = Object.keys(all).sort().map(k => `${k}=${all[k]}`).join("&");
  const sig = crypto.createHmac("sha256", secretKey).update(qs).digest("hex");
  const signed = `${qs}&signature=${sig}`;
  for (const base of urls) {
    try {
      const url = method === "POST" ? `${base}${path}` : `${base}${path}?${signed}`;
      const res = await fetch(url, {
        method,
        headers: { "X-BX-APIKEY": apiKey, "X-SOURCE-KEY": "BX-AI-SKILL",
          ...(method === "POST" ? { "Content-Type": "application/x-www-form-urlencoded" } : {}) },
        body: method === "POST" ? signed : undefined,
        signal: AbortSignal.timeout(10000),
      });
      const json = JSONBigParse.parse(await res.text());
      if (json.code !== 0) throw new Error(`BingX error ${json.code}: ${json.msg}`);
      return json.data;
    } catch (e) {
      if (!isNetworkOrTimeout(e) || base === urls[urls.length - 1]) throw e;
    }
  }
}

Code Usage Rules

• MUST copy fetchSigned verbatim -- do not simplify or rewrite
• MUST use json-bigint (JSONBigParse.parse) for response parsing -- not JSON.parse
• MUST include X-SOURCE-KEY: BX-AI-SKILL header on every request
• MUST NOT remove the domain fallback loop or isNetworkOrTimeout check

Common Calls

Place a market buy order (spend 100 USDT):

const order = await fetchSigned("prod-live", API_KEY, SECRET, "POST",
  "/openApi/spot/v1/trade/order", {
    symbol: "BTC-USDT",
    side: "BUY",
    type: "MARKET",
    quoteOrderQty: 100,
  }
);
// order.orderId, order.status, order.executedQty, order.cummulativeQuoteQty

const order = await fetchSigned("prod-live", API_KEY, SECRET, "POST",
  "/openApi/spot/v1/trade/order", {

// data.orders[].orderId, data.orders[].price, data.orders[].status

  "/openApi/spot/v1/trade/historyOrders", {
    symbol: "BTC-USDT",

Query trade fills for an order:

const data = await fetchSigned("prod-live", API_KEY, SECRET, "GET",
  "/openApi/spot/v1/trade/myTrades", {
    symbol: "BTC-USDT",
    orderId: 123456789,
  }
);
// data.fills[].price, data.fills[].qty, data.fills[].commission

Query commission rate:

const data = await fetchSigned("prod-live", API_KEY, SECRET, "GET",
  "/openApi/spot/v1/user/commissionRate", {

Agent Interaction Rules

All write operations (place order, cancel order, OCO create/cancel) require CONFIRM on prod-live. Read-only queries do not.

• prod-live: Ask user to type CONFIRM before any order placement or cancellation.
• prod-vst: No CONFIRM required. Inform user: "You are operating in the Production Simulated (VST) environment."

Step 1 — Identify the Operation

If the user's intent is unclear, present options:

What would you like to do?

• Place a new order
• Cancel an order / Cancel all orders
• Check open orders
• Check order history
• Check trade fills (transaction details)
• Check trading commission rate
• OCO order (create / cancel / query)

Step 2 — Collect symbol (if not provided)

Please select a trading pair (or type another):

• BTC-USDT
• ETH-USDT
• SOL-USDT
• BNB-USDT
• Other (format: BASE-USDT)

Step 3 — Collect side (for order placement)

Order direction:

• BUY
• SELL

Step 4 — Collect order type

Order type:

• MARKET — execute immediately at best price
• LIMIT — execute at a specific price (requires price and timeInForce)
• TAKE_STOP_LIMIT — take-profit/stop-loss limit (requires stopPrice + price)
• TAKE_STOP_MARKET — take-profit/stop-loss market (requires stopPrice)
• TRIGGER_LIMIT — trigger limit order (requires stopPrice + price)
• TRIGGER_MARKET — trigger market order (requires stopPrice)

Step 5 — Collect quantity and price

• MARKET BUY: ask for quoteOrderQty (USDT to spend) or quantity (base asset amount)
• MARKET SELL: ask for quantity (base asset amount to sell)
• LIMIT: ask for quantity and price; confirm timeInForce (default GTC)
• TAKE_STOP_LIMIT / TRIGGER_LIMIT: ask for quantity, stopPrice (trigger), and price (execution)
• TAKE_STOP_MARKET / TRIGGER_MARKET: ask for quantity and stopPrice

Step 6 — Confirm (prod-live only)

For prod-live, present a summary and ask:

You are about to place the following order on Production Live:

• Symbol: BTC-USDT
• Side: BUY
• Type: MARKET
• Amount: 100 USDT

Type CONFIRM to proceed, or anything else to cancel.

Step 7 — Execute and report

Execute the API call and return the order ID, status, and filled quantity to the user.

Cancel Order Flow

1. Ask for symbol and orderId (or clientOrderID) if not provided.
2. For prod-live: ask for CONFIRM.
3. Execute POST /openApi/spot/v1/trade/cancel.

Cancel All Open Orders Flow

1. Ask for symbol (optional — omit to cancel all pairs).
2. For prod-live: ask for CONFIRM.
3. Execute POST /openApi/spot/v1/trade/cancelOpenOrders.

OCO Order Flow

OCO (One-Cancels-the-Other) pairs a limit order with a stop-limit order; when one fills or triggers, the other is automatically cancelled.

1. Ask for symbol, side, quantity.
2. Ask for limitPrice (limit order execution price).
3. Ask for triggerPrice (stop-limit trigger price).
4. Ask for orderPrice (stop-limit execution price after trigger fires).
5. For prod-live: ask for CONFIRM.
6. Execute POST /openApi/spot/v1/oco/order.
