refactor: Update APIRequestComponent and URLComponent

Update the APIRequestComponent and URLComponent to improve functionality and error handling. In APIRequestComponent, add the ability to parse curl commands and update the build configuration accordingly. In URLComponent, include metadata in the returned data objects. These changes enhance the overall performance and user experience of the components.
