OKX API quant from scratch: from requesting a key to your first order script
Requesting an API key, how to set permissions, what the Passphrase is — and the full run from checking your balance to placing an order in Python (ccxt).
OKX · Quant / strategy trading
Grid bots, copy trading, API scripts — from signing up for OKX and opening API keys to getting your first order through, we break down every step. Before we write up a strategy, the MeowQuant desk tests it with small money on the demo account and with real funds.
* The discount follows OKX's currently published rebate / fee rules. Crypto is high-risk; nothing here is investment advice.
# MeowQuant test: confirm the API works first, then talk strategy
import ccxt
okx = ccxt.okx({
'apiKey': 'your API Key',
'secret': 'your Secret',
'password': 'your Passphrase', # OKX-specific, don't skip it
})
bal = okx.fetch_balance()
print(bal['USDT']['free']) # → confirm the funds are thereA lot of people get stuck on "which step comes first." We lay it out in the real order, and each step has a hands-on article to match.
Sign up for OKX with referral code OK30001, finish identity verification, and get an account you can trade with.
Create an API key, tick "Trade" only, and never tick "Withdraw" — that's the security floor.
Grid, copy trading, DCA, or your own script? Choose based on how much time you can spend watching the market.
Position sizing, stop-losses, demo account first — survive first, talk returns later.

For someone just starting out, "you don't have to build your own infrastructure" matters a lot. OKX puts the API, bots, demo account and copy trading in one account, so the cost of trial and error stays low.
| Capability | OKX | What it means for quant |
|---|---|---|
| REST + WebSocket API v5 | Yes | Market data, orders and account all covered; ccxt connects directly |
| Built-in grid / DCA / arbitrage bots | Yes | Run strategies without writing code |
| Strategy marketplace + copy trading | Yes | Reference parameters others have already proven |
| Demo Trading | Yes | Get it working with fake money before going live |
| Sub-accounts + API rate limits | Yes | Isolate multiple strategies, manage in bulk |
Get OKX signed up and your API set up first, then come back and pick a strategy to run. New accounts that sign up with the referral code get a fee discount — it's the closest step to actually starting.
Crypto prices swing hard, and derivatives with leverage can wipe out your entire principal. Quant and bots don't guarantee profit. Only use money you can afford to lose.
