cg.getPing()
  .then(({ data, response, endpoint }) => {
    console.log(data);
    console.log(response);
    console.log(endpoint);

  // Error Handling
  .catch(err => {
    if (err.type === APIError.SERVER) {

      console.error("API resources not found");
    } else if (err.type === APIError.DOWN) {
      // CoinGecko API Down (Error 500)

    console.log("Server online");
  } else {
    console.error("Server not responding properly");
  }
});

Async Await

(async () => {
  const cg = new CoinGeckoAPI(fetch);
  const { data, response } = await cg.getPing();
  if (data) {

    console.error("Server offline");
  }
})();
