Examples
Get funding account balances
import { RestClient } from 'okx-api';
const client = new RestClient({
apiKey: process.env.API_KEY!,
apiSecret: process.env.API_SECRET!,
apiPass: process.env.API_PASS!,
});
// All funding balances
const balances = await client.getBalances();
for (const b of balances) {
console.log(`${b.ccy}: available=${b.availBal}, frozen=${b.frozenBal}`);
}
// Single currency
const [usdtBalance] = await client.getBalances({ ccy: 'USDT' });
console.log('USDT funding balance:', usdtBalance.availBal);
Transfer from funding to trading account
const result = await client.fundsTransfer({
ccy: 'USDT',
amt: '100',
from: '6', // '6' = funding account
to: '18', // '18' = trading account
});
console.log('Transfer ID:', result[0].transId);
// Check transfer state
const state = await client.getFundsTransferState({
transId: result[0].transId,
});
console.log('Status:', state[0].state); // 'success', 'pending', 'failed'
Get deposit address
const addresses = await client.getDepositAddress({ ccy: 'USDT' });
for (const addr of addresses) {
console.log(`Chain: ${addr.chain}, Address: ${addr.addr}`);
if (addr.tag) console.log(`Memo/Tag: ${addr.tag}`);
}
Submit a withdrawal
const [withdrawal] = await client.submitWithdraw({
ccy: 'USDT',
amt: '50',
dest: '4', // '4' = on-chain
toAddr: '0xYourAddressHere',
chain: 'USDT-ERC20',
});
console.log('Withdrawal ID:', withdrawal.wdId);
Double-check the chain value against getCurrencies() output. Sending to the wrong chain results in permanent loss of funds.
Currency conversion
// 1. Get a quote to convert 100 USDT to BTC
const [quote] = await client.estimateConvertQuote({
baseCcy: 'BTC',
quoteCcy: 'USDT',
side: 'sell', // sell base (BTC) for quote (USDT)
rfqSz: '100', // amount in rfqSzCcy
rfqSzCcy: 'USDT',
quoteId: '', // leave blank for initial request
});
console.log('You will receive:', quote.toAmt, quote.toCcy);
console.log('Quote ID:', quote.quoteId);
console.log('Quote expires:', quote.clQReqId);
// 2. Execute the conversion using the quote
const [trade] = await client.convertTrade({
quoteId: quote.quoteId,
baseCcy: 'BTC',
quoteCcy: 'USDT',
side: 'sell',
sz: '100',
szCcy: 'USDT',
});
console.log('Conversion trade ID:', trade.tradeId);
Query deposit history
const deposits = await client.getDepositHistory({
ccy: 'BTC',
limit: '20',
});
for (const d of deposits) {
console.log(`${d.ccy} deposit: ${d.amt} - state: ${d.state} - txId: ${d.txId}`);
}
