Prismic.io + Angular the right way, advice needed

prismic-angular

// DRY????? :( How can I avoid to repeat $window.Prismic.Api('...', callback) ??

app.factory('Prismic', function($window, $q) {
    return {
        blogList: function(page) {
            var blogList = $q.defer();
            $window.Prismic.Api('https://thtest.prismic.io/api', function(err, Api) {
                Api.form('everything')
                    .ref(Api.master())
                    .query(Prismic.Predicates.at('document.type', 'article')).pageSize(3).page(page).submit(function(err, response) {
                        if (err) {
                            console.log(err);
                        }
                        blogList.resolve({
                            err: err,
                            result: response.results
                        });
                    });
            });
            return blogList.promise;
        },
        singleBlogPost: function(id) {
            var singleBlogPost = $q.defer();
            $window.Prismic.Api('https://thtest.prismic.io/api', function(err, Api) {
                Api.form('everything')
                    .ref(Api.master())
                    .query(Prismic.Predicates.at('document.id', id)).submit(function(err, response) {
                        if (err) {
                            console.log(err);
                        }
                        singleBlogPost.resolve({
                            err: err,
                            result: response.results
                        });
                    });
            });
            return singleBlogPost.promise;
        }
    };
});

what about this?

app.factory('Prismic', function($window, $q) {
    return {
        blogList: function(page) {
            var query = query('document.type', 'article').pageSize(3).page(page);
            return submit(query);
        },
        singleBlogPost: function(id) {
            var query = query('document.id', 'id');
            return submit(query);
        }
    };
});

function query(where, what) {
    $window.Prismic.Api('https://thtest.prismic.io/api', function(err, Api) {
        return Api.form('everything')
            .ref(Api.master())
            .query(Prismic.Predicates.at(where, what))
    });
}

function submit(query) {
    var q = $q.defer();
    query.submit(function(err, response) {
        if (err) {
            console.log(err);
        }
        q.resolve({
            err: err,
            result: response.results
        });
    });
    return q.promise;
}
