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

Query spot account balance:

const balance = await fetchSigned("prod-live", API_KEY, SECRET, "GET",
  "/openApi/spot/v1/account/balance"
);
// balance.balances[].asset, balance.balances[].free, balance.balances[].locked

Query fund account balance:

const fundBalance = await fetchSigned("prod-live", API_KEY, SECRET, "GET",
  "/openApi/fund/v1/account/balance"
);
// fundBalance.data.balance

Query all account balances (overview):

const allBalances = await fetchSigned("prod-live", API_KEY, SECRET, "GET",
  "/openApi/account/v1/allAccountBalance"
);
// allBalances[].asset, allBalances[].balance

Transfer assets (Spot → Perpetual Futures):

await fetchSigned("prod-live", API_KEY, SECRET, "POST",
  "/openApi/api/asset/v1/transfer", {
    type: "FUND_PFUTURES",
    asset: "USDT",
    amount: 100,
  }
);

Query asset transfer records:

const transfers = await fetchSigned("prod-live", API_KEY, SECRET, "GET",
  "/openApi/api/v3/asset/transferRecord", {
    type: "FUND_PFUTURES",
    startTime: 1700000000000,
    endTime: 1702731787011,
  }
);
// transfers[].asset, transfers[].amount, transfers[].type, transfers[].timestamp

Query supported coins for transfer:

const coins = await fetchSigned("prod-live", API_KEY, SECRET, "GET",
  "/openApi/api/asset/v1/transfer/supportCoins"
);
// coins[].coin, coins[].name

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.

Asset transfer operations require CONFIRM on prod-live. Read-only queries (balance, transfer records) do not.

• prod-live: Ask user to type CONFIRM before any asset transfer.
• 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?

• Check account balance (spot / fund / all accounts)
• Transfer assets between accounts
• Query transfer records
• Query supported coins for transfer
• Internal P2P transfer

Step 2 — Account Balance Query

For balance queries, ask which account type:

Which account balance would you like to check?

• Spot account balance
• Fund account balance
• All accounts overview

Step 3 — Asset Transfer Flow

1. Ask which direction:

   Transfer direction:

   • Spot → Perpetual Futures (FUND_PFUTURES)
   • Perpetual Futures → Spot (PFUTURES_FUND)
   • Spot → Standard Contract (FUND_SFUTURES)
   • Standard Contract → Spot (SFUTURES_FUND)
   • Standard Contract → Perpetual Futures (SFUTURES_PFUTURES)
   • Perpetual Futures → Standard Contract (PFUTURES_SFUTURES)

2. Ask for asset (e.g., USDT) and amount.
3. For prod-live: ask for CONFIRM.
4. Execute POST /openApi/api/asset/v1/transfer.

Step 4 — Transfer Records Query

1. Optionally ask for type (transfer direction) and time range.
2. Execute GET /openApi/api/v3/asset/transferRecord.
3. Present results in a table format: asset, amount, type, timestamp, status.
