Ask API

You need to login or signup to use the BuiltWith API.

The BuiltWith Ask API converts natural language questions into BuiltWith list lookups and returns matching websites with the same core attributes as the Lists API.

A normal lookup always returns a sample. Add COMMIT=true to create and run a full Ask report, returned in sequence order with paging through NEXTOFFSET.

The general access method is as follows -
https://api.builtwith.com/ask1/api.[xml|json|txt|csv|tsv]?KEY=00000000-0000-0000-0000-000000000000&QUERY=Magento%20websites%20in%20Spain

Reference https://api.builtwith.com/llms.txt
Add the BuiltWith Ask API to my app. Make a call to ask1/api.json for "Magento websites in Spain" and page committed results with NEXTOFFSET.

You must provide your API key in each Ask API lookup.

Your API key is
00000000-0000-0000-0000-000000000000.

Examples for making Ask API requests:

• C#
• Python
• Node.js
• cURL

var client = new HttpClient();
var url = "https://api.builtwith.com/ask1/api.json?KEY=00000000-0000-0000-0000-000000000000&QUERY=Magento%20websites%20in%20Spain";
var body = await client.GetStringAsync(url);
Console.WriteLine(body);

import requests
response = requests.get("https://api.builtwith.com/ask1/api.json", params={
    "KEY": "00000000-0000-0000-0000-000000000000",
    "QUERY": "Magento websites in Spain"
})
print(response.json())

const params = new URLSearchParams({
  KEY: '00000000-0000-0000-0000-000000000000',
  QUERY: 'Magento websites in Spain'
});
fetch('https://api.builtwith.com/ask1/api.json?' + params)
  .then(r => r.json())
  .then(console.log);

curl "https://api.builtwith.com/ask1/api.json?KEY=00000000-0000-0000-0000-000000000000&QUERY=Magento%20websites%20in%20Spain"

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.

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.
