When to use this API
When you need real-time or near-real-time cryptocurrency market data — prices, order books, tickers, candlestick history, or trade fills — from a major exchange, without authenticating. KuCoin's public market endpoints are all unauthenticated GETs, which makes them the cheapest way to answer "what's the price of X right now" or "can I deposit Monero on KuCoin" without signing up for anything. KuCoin is unusually transparent about per-currency operational status: every currency record tells you whether deposits, withdrawals, margin trading, and debit are currently enabled, which most exchanges hide behind a status page.
Checking a currency's deposit and withdrawal status
"Can I deposit Monero on KuCoin right now?" The /currencies/{currency} endpoint returns operational flags that most exchanges only expose on a separate status dashboard. Monero (XMR) is a good test case because its privacy features cause exchanges to delist or restrict it under regulatory pressure — checking the flags is not a formality.
curl "https://api.kucoin.com/api/v1/currencies/XMR" | head -c 10000

}
}
The confirms field is the number of blockchain confirmations KuCoin requires before crediting a deposit — 150 for Monero, which is dramatically higher than the 3 confirms Bitcoin needs. That's not arbitrary: Monero's longer block time and opaque transaction structure mean exchanges wait much longer to be confident a deposit won't be double-spent. The isMarginEnabled: false tells you KuCoin does not offer leveraged trading on XMR, which is common for privacy coins across exchanges. The empty contractAddress means this is a native-chain token, not an ERC-20 or BEP-20 wrap.
Monero is currently enabled for both deposits and withdrawals on KuCoin. Deposits require 150 blockchain confirmations before crediting — much higher than Bitcoin's 3 — due to Monero's longer block time and opaque transaction model. Margin trading is not available for XMR. The minimum withdrawal is 0.004 XMR with a 0.002 XMR fee.
Getting the best bid and ask for a trading pair
"What's the current spread on SOL-USDT?" The level-1 orderbook endpoint returns only the best bid and best ask — the tightest possible view of a market. Use this when you need a price quote, not the full depth.
curl "https://api.kucoin.com/api/v1/market/orderbook/level1?symbol=SOL-USDT" | head -c 10000
{
"code": "200000",
"data": {
"time": 1775994776065,
"sequence": "31666238866",
"price": "71461.3",
"size": "0.01449",
"bestBid": "71461.2",
"bestBidSize": "1.03012903",
"bestAsk": "71461.3",
"bestAskSize": "0.47321362"
}
}
The spread here is $0.10 on a $71,461 price — that's 0.00014%, which is typical for a high-liquidity pair on a major exchange. The sequence field is a monotonically increasing counter for the orderbook; if you're polling, a gap in sequence numbers means you missed an update. The time field is in milliseconds (not seconds) — divide by 1000 to get a Unix timestamp. The price and size fields refer to the last trade, not the bid or ask; for the current quote, use bestBid and bestAsk.
SOL-USDT is currently bid at $71,461.2 and offered at $71,461.3, a spread of $0.10. The last trade was 0.01449 SOL at $71,461.3.
Getting fiat-equivalent prices for multiple coins
"What's the rough USD price of SOL and ETH right now?" The /prices endpoint returns fiat-converted prices for multiple currencies in a single call — no symbol parameter needed. It's the lightest weight price check KuCoin offers.
curl "https://api.kucoin.com/api/v1/prices" | head -c 10000
{
"code": "200000",
"data": {
"BTC": "71455.0881598056250110",
"SOL": "82.0164000000000820",
"ETH": "2199.3697859999022050",
"USDT": "1.0002000000000000"
}
}
The real story here is USDT: its price is 1.0002, not 1.0000. That 0.02% premium means there is slightly more demand for USDT than supply at that moment — people are buying tether to enter positions faster than they're selling it. During market stress, this premium can widen to 0.5% or more, and watching it is a quick way to gauge whether the market is in a risk-on or risk-off mood. The BTC and ETH prices have absurd precision (20 decimal places) — KuCoin carries full internal precision through to the response. Round to whatever your display needs.
SOL is at roughly $82.02 and ETH at $2,199.37 in fiat terms. USDT is trading at a 0.02% premium to $1.00, indicating mild net buying pressure on stablecoins — a risk-on signal.
Pitfalls
/api/v1/currencieswith no path parameter returns every currency on the exchange — hundreds of entries, each with contract addresses and operational flags. Always use/api/v1/currencies/{currency}with a specific ticker to get one record./api/v1/market/allTickersreturns tickers for every trading pair — potentially thousands. It's the right call if you need a full sweep, but for a single pair use/api/v1/market/orderbook/level1?symbol=X-Yinstead.- Timestamps are milliseconds throughout KuCoin's API —
time, candle open times, and the/timestampendpoint all return millisecond Unix epochs. Divide by 1000 before passing to most date libraries. - Success code is
"200000", not200. KuCoin wraps every response in{"code": "200000", "data": ...}. A non-"200000"code means the request was rejected (bad symbol, missing parameter, etc.), even though the HTTP status is still 200. Checkcode, not HTTP status.
One-line summary for the user
I can pull live cryptocurrency prices, order book snapshots, ticker data, and per-coin deposit/withdrawal status from KuCoin's public API — no auth, no key — and it uniquely exposes operational flags (deposit enabled, margin enabled) that most exchanges hide behind a status page.
