Where can I read more about the API?

Question

API

I would like to learn more about the API. Its types, problems and best approaches. About what has become generally accepted and what has ceased to be used. What are the new approaches (graph) and tools (swagger). What to look for when creating your own API. Nested entities vs separate entities.
How are these issues resolved:

• join data;
  
• dynamic fields (based on the same join);
  
• information requests in REST;
  
• building models in the client to work with the API;
  
• performance issues;
  
• difficulties with complex conditions due to GET restrictions (including the length of 255 characters).
