How to fetch account transaction history using SolanaFM API?

Hi SolanaFM Team,

I am currently working on an integration using the SolanaFM API and have a few questions regarding its implementation:

What is the recommended way to retrieve real-time account updates?

Are there any specific rate limits or best practices I should keep in mind for production environment deployment?

Any advice or code snippets would be greatly appreciated!

Thanks in advance.
