func main() {

	url := "https://fishbase.ropensci.org/species?limit=10&offset=0"

	req, _ := http.NewRequest("GET", url, nil)

	req.Header.Add("Accept", "application/vnd.ropensci.v6+json")

	res, _ := http.DefaultClient.Do(req)

	defer res.Body.Close()
	body, _ := io.ReadAll(res.Body)

	fmt.Println(string(body))
