Technology lookup

Find out the technology stack of any website, such as the CMS or ecommerce platform. Perform near-instant queries against our comprehensive database of millions of websites or analyse websites live for real-time results.

In addition to technologies, responses optionally include company details, verified email addresses, phone numbers, social media profiles, locale information, keywords, metadata and more.

Endpoint

GET https://api.wappalyzer.com/v2/lookup/

Properties

Property	Description
Execution	Synchronous Asynchronous when using `recursive=true`
Request timeout	30 seconds
Rate limit	5 requests per second (up to 10 URLs per request)
Pricing	1 credit per URL 2 credits per URL when using `live=true` with `recursive=true`

Query string parameters

Name	Description
`urls` (required)	Between one and ten website URLs, comma separated. Example: `https://example.com,https://example.org`. Multiple URLs are not supported with `recursive=false`.
`live`	Scan websites in real-time. Defaults to `false` to return cached results from our database (faster and more complete). If no record is found, `live=true` is automatically used instead. Use `recursive=false` to get live results in the same request.
`recursive`	Index multiple pages (follows internal website links for increased coverage). Defaults to `true` for best results. If no record is found or `live=true` is used, using `recursive=true` causes the request to be completed asynchronously, meaning technologies will not be included in the initial response and the website is being crawled. To get the results when they become available, use `callback_url` or repeat the request at a later time (free for up to one hour). A crawl can take up to 15 minutes. We recommend using `callback_url` or repeating the request up to three times every five minutes. When using both `live=true` and `recursive=true`, `callback_url` is required and requests cost two credits instead of one.
`callback_url`	When an asynchronous request completes, a `POST` request is made to the callback URL with the results. A callback URL is an public endpoint hosted on your own server. Example: `https://yourdomain.com/wappalyzer`). Required when using both `live=true` and `recursive=true`.
`sets`	Comma-separated list of additional field sets to include in the results (e.g. `meta,social`). Some fields require an eligible plan. See Fields. Use `all` to include all fields.
`denoise`	Exclude low confidence results. Defaults to `true`. Setting this to `false` yields more results but is more likely to include false positives.
`min_age`	Return results that have been verified at least once before `min_age` months ago. Defaults to `0` for most recent results. Use a higher value in combination with `squash=false` and `max_age` for historic results grouped by month (up to 12 months per request).
`max_age`	Return results that have been verified at least once in the last `max_age` months. Defaults to `2` for best results. To get the most up-to-date but fewer results, use `max_age=1`. For real-time results, use `live=true` instead. Use a higher value to get more but less recently verified results. These results are more likely to include websites that no longer use the technology. Use a higher value in combination with `squash=false` and optionally `min_age` for historic results grouped by month (up to 12 months per request).
`squash`	Merge monthly results into a single set. Defaults to `true`. Set to `false` to group results by month.

Response callback

A callback URL is a public endpoint hosted on your own server. If you request a domain that we haven't seen before, you'll initially get an empty response while the website is being indexed. Minutes later, your callback URL will receive a POST request with the final results. Without a callback URL, you will not get these results unless you make another request or use recursive=false to peform a shallow scan.

To verify that the request was made by Wappalyzer, enable callback signatures .

Examples

Use case

This method provides the most complete results. Results are recently verified and cached for speed. When no record is found, a deep scan is performed and results are sent to your callback URL within minutes.

Request

In this example we request two URLs with a callback URL and the default options.

curl -H "x-api-key: <your api key>" "https://api.wappalyzer.com/v2/lookup/?urls=https://example.com,https://example.org&callback_url=https://yourdomain.com"

Response (success)

We get a result for each URL, in this case one successful and one empty. An empty response means the website has either not been indexed or no technologies were found. The crawl field indicates that a crawl has been initiated. When ready, results will be sent to the callback URL provided.

Callback response

The callback URL will receive a POST request when results become available. The callback URL will be invoked seperately for each requested URL.
