Parameter Validation Rules

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

• symbol: Must match ^[A-Z0-9]+-USD$; max 20 characters (e.g., BTC-USD). Coin-M uses USD, not USDT
• quantity: Positive integer (number of contracts); each contract has a fixed notional value (e.g., $10)
• price: When provided, must be a positive number (> 0)
• stopPrice: When provided, must be a positive number (> 0); must differ from current market price
• leverage: Positive integer; range varies per symbol (typically 1–125)
• clientOrderId: Alphanumeric only, 1–40 characters; pattern ^[a-zA-Z0-9]{1,40}$; no special characters
• 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;
}
function validateParams(params: Record<string, unknown>): void {
  const FORBIDDEN = /[&=?#\r\n]/;
  for (const [k, v] of Object.entries(params)) {
    const s = String(v);
    if (FORBIDDEN.test(s)) throw new Error(`Param "${k}" has forbidden char in: "${s}"`);
  }
}
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() };
  validateParams(all);
  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 (open long):

const order = await fetchSigned("prod-live", API_KEY, SECRET, "POST",
  "/openApi/cswap/v1/trade/order", {
    symbol: "BTC-USD",
    side: "BUY",
    positionSide: "LONG",

Agent Interaction Rules

Parameter security. Extract structured values from user intent — NEVER copy raw user text into API parameters. Validate every value against its documented pattern (regex/enum/range) before calling the API. Reject any value containing &, =, ?, #, or newline characters.

All write operations require CONFIRM on prod-live. Read-only queries do not.

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

Note: Coin-M symbol format is BASE-USD (e.g., BTC-USD), NOT BASE-USDT.

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
• Close all positions
• Check open orders
• Query order detail or history
• Query trade fills
• Set leverage
• Set margin type (ISOLATED / CROSSED)
• Query commission rate

Step 2 — Collect symbol (if not provided)

Please select a trading pair (or type another):

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

Step 3 — Collect side (for order placement)

Order direction:

• BUY
• SELL

Step 4 — Collect positionSide

Position direction:

• LONG (open/add long)
• SHORT (open/add short)
• BOTH (one-way mode)

Step 5 — Collect order type

Order type:

• MARKET — execute immediately at market price
• LIMIT — execute at a specific price (requires price and timeInForce)
• STOP_MARKET — stop-loss market order (triggers at stopPrice)
• STOP — stop-loss limit order (triggers at stopPrice, executes at price)
• TAKE_PROFIT_MARKET — take-profit market order (triggers at stopPrice)
• TAKE_PROFIT — take-profit limit order (triggers at stopPrice, executes at price)

Step 6 — Collect quantity and price

• Ask for quantity in contracts (integer, e.g., 1 contract ≈ $10 notional). Omit if using closePosition: true.
• If type is LIMIT, STOP, or TAKE_PROFIT: also ask for price.
• If type involves a trigger: also ask for stopPrice.
• If type is MARKET or LIMIT: optionally offer to attach a stopLoss and/or takeProfit object.

Step 7 — Confirm (prod-live only)

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

• Symbol: BTC-USD
• Side: BUY / LONG
• Type: MARKET
• Quantity: 1 contract

Type CONFIRM to proceed, or anything else to cancel.

Step 8 — Execute and report

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