I am tring to get League of Legends champion informations from LOL static database. Link is given below.

Also tree respresentation:

My goal is to get all hero informations with iteration by range of known hero names as slice. You can check the code. I need only a couple of fields but the main tag is varies with every new request.

func GetHeroInfo(heroName string) *LolHeroInfo {
getUrl := fmt.Sprintf("http://ddragon.leagueoflegends.com/cdn/12.2.1/data/en_US/champion/%s.json", heroName)
fmt.Println(getUrl)
resp, err := http.Get(getUrl)
if err != nil {
    fmt.Println(err)
    return nil
}
defer resp.Body.Close()
read, err := io.ReadAll(resp.Body)
if err != nil {
    fmt.Println(err)
    return nil
}
heroGoverted := LolHeroInfo{}
err = json.Unmarshal(read, &heroGoverted)
if err != nil {
    fmt.Println("unmarshall failed:", err)
    return nil
}
return &heroGoverted }

Struct type LolHeroInfo is structifyed from this link:

heroInfo := lib.GetHeroInfo(lolHeroes[i])
    for _, v := range heroInfo.Data { //unmarshalled to first struct
        a := lib.HeroInfoStruct{} //data field; second struct
        a = v
        fmt.Println(a.Lore)// now i can reach to every field that i need
    }
