# Waiting for CSS Using the **wait\_for\_css** parameter, you can make the API wait for 10 seconds until a CSS selector appears. The waiting time is set using the **timeout** parameter; in case of failure, its value can be customized. If after 10 seconds, the CSS selector does not appear in DOM, the request is marked as failed, and thus, you will not be charged for it. You can find on the right side a sample selector for the **wait\_for\_css** parameter. The API will look for an element that has **.firstHeading class**. ### Wait for CSS examples > **`GET https://scrape.shifter.io/v1?api_key=api_key&url=https://example.com&wait_for_css=.firstHeading&render_js=1`** **⇡ Input** {% tabs %} {% tab title="cURL" %} ```url curl --request GET --url "https://scrape.shifter.io/v1?api_key=api_key&url=https://example.com&wait_for_css=.firstHeading&render_js=1" ``` {% endtab %} {% tab title="NodeJS" %} ```javascript const http = require("https"); const options = { "method": "GET", "hostname": "scrape.shifter.io", "port": null, "path": "/v1?api_key=api_key&url=https://example.com&wait_for_css=.firstHeading&render_js=1", "headers": {} }; const req = http.request(options, function (res) { const chunks = []; res.on("data", function (chunk) { chunks.push(chunk); }); res.on("end", function () { const body = Buffer.concat(chunks); console.log(body.toString()); }); }); req.end(); ``` {% endtab %} {% tab title="Python" %} ```python import http.client conn = http.client.HTTPSConnection("scrape.shifter.io") conn.request("GET", "/v1?api_key=api_key&url=https://example.com&wait_for_css=.firstHeading&render_js=1") res = conn.getresponse() data = res.read() print(data.decode("utf-8")) ``` {% endtab %} {% tab title="PHP" %} ```php "https://scrape.shifter.io/v1?api_key=api_key&url=https://example.com&wait_for_css=.firstHeading&render_js=1", CURLOPT_RETURNTRANSFER => true, CURLOPT_ENCODING => "", CURLOPT_MAXREDIRS => 10, CURLOPT_TIMEOUT => 30, CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1, CURLOPT_CUSTOMREQUEST => "GET", ]); $response = curl_exec($curl); $err = curl_error($curl); curl_close($curl); if ($err) { echo "cURL Error #:" . $err; } else { echo $response; } ``` {% endtab %} {% tab title="Golang" %} ```go package main import ( "fmt" "net/http" "io/ioutil" ) func main() { url := "https://scrape.shifter.io/v1?api_key=api_key&url=https://example.com&wait_for_css=.firstHeading&render_js=1" req, _ := http.NewRequest("GET", url, nil) res, _ := http.DefaultClient.Do(req) defer res.Body.Close() body, _ := ioutil.ReadAll(res.Body) fmt.Println(res) fmt.Println(string(body)) } ``` {% endtab %} {% tab title="Java" %} ```java HttpResponse response = Unirest.get("https://scrape.shifter.io/v1?api_key=api_key&url=https://example.com&wait_for_css=.firstHeading&render_js=1") .asString(); ``` {% endtab %} {% tab title=".NET" %} ``` var client = new RestClient("https://scrape.shifter.io/v1?api_key=api_key&url=https://example.com&wait_for_css=.firstHeading&render_js=1"); var request = new RestRequest(Method.GET); IRestResponse response = client.Execute(request); ``` {% endtab %} {% tab title="Ruby" %} ```ruby require 'uri' require 'net/http' require 'openssl' url = URI("https://scrape.shifter.io/v1?api_key=api_key&url=https://example.com&wait_for_css=.firstHeading&render_js=1") http = Net::HTTP.new(url.host, url.port) http.use_ssl = true http.verify_mode = OpenSSL::SSL::VERIFY_NONE request = Net::HTTP::Get.new(url) response = http.request(request) puts response.read_body ``` {% endtab %} {% endtabs %} **⇣ Output** ``` Example Domain
