API3 arbitrage explained

Right now Api3 (API3) trades on 9 venues we scan: 9 perpetual markets, 6 spot markets and 0 DEX pools. The lowest ask is on MEXC perp at $0.3096 and the highest bid on OKX spot at $0.3103.

The widest API3 perpetual spread is between MEXC and Variational: long API3 on MEXC at $0.3096 and short on Variational at $0.3103 for +0.23% gross, or +0.07% after the 0.16% two-leg fee model. No transfer is needed: both positions stay on their exchanges until the prices converge. The funding difference on this pair is +0.273% per day, which the position collects while it is open.

For a spot–perpetual (cash-and-carry) trade, the best API3 route is to buy spot on KuCoin and short the perpetual on Variational: +0.03% gross, -0.17% net, with -0.297% a day of funding on the short leg.

Spot–spot API3 arbitrage (buy on KuCoin, withdraw, deposit and sell on Binance) shows +0.03% gross right now. It only works if withdrawals on the buying exchange and deposits on the selling exchange are open, so check the D/W dots before moving coins.

Small API3 gaps usually disappear after fees, slippage and funding. Look at the Net column, the executable Depth and the spread history before trading: a gap that has been open for days is a different trade from a one-minute spike.
