First you'll want to get a sessionid from the auth endpoints.
Second you'll want to execute a search from the search endpoints and record the search id. This will require the sessionid.
Then you'll want to get the results from the search endpoints after verifying the search has completed. Both steps here will require the search id & sessionid.
There's plenty of documentation on the Splunk rest api. There is no need to create your own api.

As we aren't in the business of writing your code for you, I hope you can use a search engine to fill in the blanks.
Best of luck! Let us know if you have difficulties with the api.
