What is Coinbase advanced API?

Could you elaborate on what Coinbase's Advanced API offers to developers and traders? I'm particularly interested in understanding its capabilities and how it differs from Coinbase's standard API. Does it provide access to more robust trading algorithms, real-time market data, or enhanced security features? Additionally, what are the requirements and limitations for using the Advanced API? I'm aiming to build a custom trading solution and wondering if the Advanced API would be a suitable fit for my needs.
