Ajax GET with Reagent

I am doing an Ajax GET from my Reagent application, to load some stuff from the database.

I am not entirely sure what is the best way of getting the result of such ajax call to my page, considering that if I put it in an atom, then Reagent automatically re-renders a component when an atom is dereferenced, which means I get an infinite sequence of ajax calls.

For some code,

(def matches (atom nil))

(defn render-matches [ms]
  (reset! matches (into [:ul] (map (fn [m] ^{:key m}[:li m])
                                   (walk/keywordize-keys (t/read (t/reader :json) ms)))))

This function basically creates a [:ul [:li "Stuff here"] [:li "And here"]]

Which i would like displayed on my page, which now has the following code.

(defn standings-page []
  (GET "/list-matches"
       {:handler render-matches})
  @matches)
