Code Examples

Here are implementation examples in different programming languages for making API requests:

var client = new HttpClient();
var request = new HttpRequestMessage
{
    Method = HttpMethod.Get,
    RequestUri = new Uri("https://api.builtwith.com/trends/v6/api.json" +
                        "?KEY=00000000-0000-0000-0000-000000000000&TECH=Magento"),
};
using (var response = await client.SendAsync(request))
{
    response.EnsureSuccessStatusCode();
    var body = await response.Content.ReadAsStringAsync();
    Console.WriteLine(body);
}
import requests
url = "https://api.builtwith.com/trends/v6/api.json"
params = {
    'KEY': '00000000-0000-0000-0000-000000000000',
    'TECH': 'Magento'
}
response = requests.get(url, params=params)
print(response.json())
<?php
$url = "https://api.builtwith.com/trends/v6/api.json";
$params = array(
    'KEY' => '00000000-0000-0000-0000-000000000000',
    'TECH' => 'Magento'
);
$url_with_params = $url . '?' . http_build_query($params);
$response = file_get_contents($url_with_params);
$data = json_decode($response, true);
print_r($data);
?>
const https = require('https');
const url = 'https://api.builtwith.com/trends/v6/api.json?KEY=00000000-0000-0000-0000-000000000000&TECH=Magento';
https.get(url, (res) => {
    let data = '';
    res.on('data', (chunk) => {
        data += chunk;
    });
    res.on('end', () => {
        console.log(JSON.parse(data));
    });
}).on('error', (err) => {
    console.log('Error: ' + err.message);
});

Special Domains

We maintain two lists of use for you when looking up domains. Ignore lists and BuiltWith Suffix lists.

Ignore List
This is our own internal list of domains we do not index. They are either blocked, contains too many misleading technologies or too many subdomains with user generated content.

BuiltWith Suffix List
This is based on the Public Suffix List but includes many additional entries for companies with subdomains that should be considered top level domains. This list provides us with better visibility for internal websites for example it brings northernbeaches.nsw.gov.au to the top level over nsw.gov.au.

Ignore Domains (XML, JSON or TXT)
https://api.builtwith.com/ignoresv1/api.json
Suffix Domains (XML, JSON or TXT)
https://api.builtwith.com/suffixv1/api.json
Error Codes

Note error messages in this format cannot be guaranteed, your implementation should also consider non-200 response codes as errors. The Lookup property will be null (json) or not provided (xml) if the error is server related. View all potential well-formed error codes.

Terms of Use

Our standard terms cover the use all of our APIs.

In general, you can use the API to enhance your product in many ways. The only limitation is you cannot resell the data as-is or provide duplicate functionality to builtwith.com and its associated services.
