BingX Coin-M (CSwap) Trade

Authenticated trading endpoints for BingX Coin-M inverse perpetual futures. All endpoints require HMAC SHA256 signature authentication.

Coin-M contracts are coin-margined (settled in the base asset, e.g., BTC). Symbol format is BASE-USD (e.g., BTC-USD, ETH-USD).

Base URLs: see references/base-urls.md | Authentication: see references/authentication.md

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;
}
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 (open long):

const order = await fetchSigned("prod-live", API_KEY, SECRET, "POST",
  "/openApi/cswap/v1/trade/order", {
    symbol: "BTC-USD",
    side: "BUY",
    positionSide: "LONG",
    type: "MARKET",
    quantity: 1,
  }
);
// order.orderId, order.symbol, order.side, order.type

Place a limit sell order (open short):

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

  "/openApi/cswap/v1/trade/cancelOrder", {
    symbol: "BTC-USD",
    orderId: 1809841379603398656,
  }
);

Cancel all open orders for a symbol:

await fetchSigned("prod-live", API_KEY, SECRET, "DELETE",
  "/openApi/cswap/v1/trade/allOpenOrders", {
    symbol: "BTC-USD",
  }
);

Query open orders:

const data = await fetchSigned("prod-live", API_KEY, SECRET, "GET",
  "/openApi/cswap/v1/trade/openOrders", {
    symbol: "BTC-USD",
  }
);
// data.orders: array of open order objects

Set leverage:

await fetchSigned("prod-live", API_KEY, SECRET, "POST",
  "/openApi/cswap/v1/trade/leverage", {
    symbol: "BTC-USD",
    side: "LONG",
    leverage: 10,
  }
);

Set margin type:

await fetchSigned("prod-live", API_KEY, SECRET, "POST",

const data = await fetchSigned("prod-live", API_KEY, SECRET, "GET",
  "/openApi/cswap/v1/user/commissionRate", {}
);
// data.takerCommissionRate, data.makerCommissionRate

Agent Interaction Rules

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.

Cancel Order Flow

  1. Ask for orderId (or clientOrderId) if not provided.
  2. For prod-live: ask for CONFIRM.
  3. Execute DELETE /openApi/cswap/v1/trade/cancelOrder.

Leverage Settings Flow

  1. Ask for symbol if not provided.
  2. Ask for position side (LONG / SHORT).
  3. Ask for leverage value (e.g., 1–50 for BTC-USD).
  4. For prod-live: ask for CONFIRM.
  5. Execute POST /openApi/cswap/v1/trade/leverage.

Margin Type Flow

  1. Ask for symbol if not provided.
  2. Present options: ISOLATED or CROSSED.
