Phemex API — how to get keys, cost & fees
Phemex is a derivatives-first exchange with a low-latency contract and spot API over REST and WebSocket, popular for perpetuals and a zero-fee spot tier on a subscription.
What the API does & cost
| Use | Cost |
|---|---|
| Market data | Free |
| Contract taker | ~0.06% |
| Spot taker | ~0.1% (0% on premium) |
| API access | Free |
Phemex prices contracts in a scaled integer format (e.g. price × 10,000) — read the contract spec carefully or your order sizes will be off by orders of magnitude.
How to get your Phemex API keys
Log in at phemex.com, open Account → API Management, create a key, set permissions, and copy the secret once.
Security — read this
Never share your secret — it's shown once and can't be recovered (regenerate if leaked). For data-only bots enable read-only. Always whitelist your server IP, and never enable withdrawals on an API key unless you truly need it.
Alternatives
Bybit is the closest derivatives-focused alternative. Compare the big three first: Binance, Bybit, OKX. For pure price data, CoinGecko is simpler.
