Which HTTP methods are standard for REST APIs?

The standard HTTP methods for REST APIs are GET, PUT, POST, and DELETE. These correspond to the common CRUD (Create, Read, Update, Delete) operations. GET retrieves data, POST creates new data, PUT updates existing data, and DELETE removes data. The other options include non-standard or incorrect HTTP methods. "ERASE" and "CHANGE" are not standard HTTP methods. "MOD" is also not a standard HTTP method; "PUT" is used for modification (updating). Understanding these standard methods is fundamental for working with RESTful web services.
