You can get access to the same trading APIs GSCO has access to. It does not require much either - the biggest difference between you, me, Jenny from the Block and GSCO is that they can carry much higher risk and provide much higher liquidity and access to exotic markets. Exotic markets are not liquid, so they are not really interesting. If trading is not your primary business, you really do not want to do API trades.
