I was trying to create a customized api which internally sends a request to geocode service , pass the point to our own feature service to get other attribute information and return same thing in json format. i was planning to use JavaScript api to manage above functionalities. However, How to provide a API End point to the user and they can consume to get the customized output in json. I would have given directly feature service URL, However, it does only limited functionality. I want to add multiple functionalities in to it like geocoding, pass the point to different feature services to get the linked information
