How to get your Phemex API keys

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.
