BingX Coin-M (CSwap) Market Data

Public market data for BingX Coin-M inverse perpetual futures. No HMAC signature required, but a timestamp query parameter is required for all endpoints.

Parameters

Common Parameters

• symbol: Trading pair in BASE-USD format (e.g., BTC-USD, ETH-USD). Note: Coin-M uses USD, not USDT.
• limit: Number of results to return. Default and max vary per endpoint.
• startTime: Start timestamp in milliseconds (e.g., 1735693200000)
• endTime: End timestamp in milliseconds (e.g., 1735693200000)
• interval: Kline/candlestick interval (see Enums below)

Enums

• interval: 1m | 3m | 5m | 15m | 30m | 1h | 2h | 4h | 6h | 12h | 1d | 3d | 1w | 1M

Parameter Validation Rules

• symbol: Must match ^[A-Z0-9]+-USD$; max 20 characters (e.g., BTC-USD). Coin-M uses USD, not USDT
• limit: Positive integer; default and max vary per endpoint
• startTime / endTime: Unix timestamps in milliseconds; endTime must be ≥ startTime
• interval: Must exactly match one of the enum values above

Quick Start

Base URLs: see references/base-urls.md

TypeScript helper:

CONSTRAINT: You MUST copy the coinmMarket function below verbatim when generating code. Do NOT rewrite the request or JSON parsing logic. Only modify: (1) BASE_URLS entries for custom environments, (2) business parameters passed to coinmMarket.

import JSONBig from "json-bigint";
const JSONBigParse = JSONBig({ storeAsString: true });
// Base URLs — see references/base-urls.md for all environments
// Domain priority: .com is mandatory primary; .pro is fallback for network/timeout errors ONLY.
const BASE_URLS = ["https://open-api.bingx.com", "https://open-api.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 coinmMarket(
  path: string,
  params: Record<string, string | number> = {}
): Promise<unknown> {
  const query = new URLSearchParams(
    Object.entries(params).map(([k, v]) => [k, String(v)])
  ).toString();
  for (const base of BASE_URLS) {
    try {
      const url = `${base}${path}${query ? `?${query}` : ""}`;
      const res = await fetch(url, {
        headers: { "X-SOURCE-KEY": "BX-AI-SKILL" },
        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 === BASE_URLS[BASE_URLS.length - 1]) throw e;
    }
  }
}

Code Usage Rules

• MUST copy coinmMarket 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

24h ticker price for BTC-USD:

const ticker = await coinmMarket("/openApi/cswap/v1/market/ticker", {
  symbol: "BTC-USD",
});
// ticker.lastPrice, ticker.priceChangePercent, ticker.volume

Order book depth for BTC-USD:

const depth = await coinmMarket("/openApi/cswap/v1/market/depth", {
  symbol: "BTC-USD",
});
// depth.bids: [price, qty][], depth.asks: [price, qty][]

1-hour klines (last 100 candles):

const klines = await coinmMarket("/openApi/cswap/v1/market/klines", {
  symbol: "BTC-USD",
  interval: "1h",
  limit: 100,
});
// Each item: [openTime, open, high, low, close, volume, closeTime]

Mark price & current funding rate:

const premium = await coinmMarket("/openApi/cswap/v1/market/premiumIndex", {
  symbol: "BTC-USD",
});
// premium.markPrice, premium.lastFundingRate, premium.nextFundingTime

Open interest:

const oi = await coinmMarket("/openApi/cswap/v1/market/openInterest", {
  symbol: "BTC-USD",
});
// oi.openInterest, oi.symbol, oi.time

All contract specifications:

const contracts = await coinmMarket("/openApi/cswap/v1/market/contracts");
// Array of contract objects: symbol, pricePrecision, minTickSize, minTradeValue, status

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.

cswap-market provides public read-only market data. No HMAC signature required (only timestamp parameter needed), no CONFIRM needed. The interaction goal is to collect query parameters.

Note: Coin-M contract trading pair format is BASE-USD (e.g. BTC-USD), not BASE-USDT.

Operation Identification

When the user's request is vague (e.g. "check Coin-M market" or "look at BTC inverse contract"), first identify what type of data they want to query:

Please select the market data type:

• Price / 24h change — ticker
• Order book depth — depth
• K-lines / Candlesticks — klines
• Mark price / Funding rate — premiumIndex
• Open interest — openInterest
• Contract specification list — contracts

When symbol is missing

Applicable endpoints: depth, klines, openInterest

Please select a trading pair (or type another):

• BTC-USD
• ETH-USD
• BNB-USD
• Other (enter manually, format: BASE-USD)

If the trading pair can be inferred from context (e.g. "BTC K-lines today" or "Ethereum inverse contract funding rate"), infer it automatically without asking again.

When interval is missing (klines endpoint only)

Please select a K-line interval:

• 1m (1 minute)
• 5m (5 minutes)
• 15m (15 minutes)
• 1h (1 hour)
• 4h (4 hours)
• 1d (daily)
• 1w (weekly)

limit handling

• klines: default 100, no need to ask — inform the user "returning the most recent 100 K-lines by default"

Endpoints where symbol is optional

symbol is optional for ticker and premiumIndex. If the user does not specify, query all contracts and inform the user; if a trading pair is specified, query only that pair.
