A Hands-On Comparison Based on Fees, API, and RebatesIf you're an crypto API trader, choosing the right trading venue isn't just about liquidity — it's about infrastructure.Both Perpetual DEX (Perp DEX) and Centralized Exchanges (CEX) offer leverage, deep markets, and 24/7 trading. But under the surface, they differ dramatically in execution speed, API performance, and — most critically — rebate access.This article breaks down how Perp DEX and CEX compare for crypto API-driven trading strategies, and how to choose the best setup for your crypto bots.⚙️ What Are We Comparing?We’ll evaluate each category from an crypto API trader's point of view, focusing on factors that directly impact automation, cost, and uptime:- Fee structure- Rebate access- API design & performance- Liquidity depth & slippage- Operational friction (KYC, withdrawals, downtime)💸 1.
