usage

var req struct {
		Code string `json:"code"`
	}

As the code above shows, the code you want to run should be in the code field of the request body as a string. The method should be POST and the content type should be application/json.

type Response struct {
	Status        int    `json:"status"`
	CompileOutput string `json:"compileOutput"`
	RunOutput     string `json:"runOutput"`
}

The response is a json object with three fields: status, compileOutput and runOutput. The status field is the status code of the coderunning. It is 1 if compiled correctly and 0 if not. The compileOutput field is the output of the compiler. The runOutput field is the output of the execution of the code.
