The Tech Stack Detector API returns structured data about the technologies used on a specified website. This includes information extracted from HTML, scripts, meta tags, cookies, and response headers.
The key fields in the response include "success" (indicating the request status), "url" (the analyzed website), "status_code" (HTTP response code), "total_detected" (number of technologies found), and "technology_names" (list of detected technologies).
The response data is organized in a JSON format, with a clear structure that includes a success flag, the analyzed URL, status code, total detected technologies, and an array of technology names.
The API provides information on various web technologies, including content delivery networks, analytics tools, frameworks, and libraries detected from the website's HTML and other elements.
Users can customize their requests by specifying the target URL in the JSON POST request body. This allows for analysis of any website to detect its technology stack.
Typical use cases include competitive analysis, technology audits, market research, and identifying potential technology partners by understanding the tech stacks of various websites.
Data accuracy is maintained through continuous updates and checks against a wide range of sources, ensuring that the technologies detected are current and relevant.
Users can utilize the returned data to inform decisions on technology adoption, identify trends in web development, and enhance their own website's performance by learning from competitors' tech stacks.
To obtain your API key, you first need to sign in to your account and subscribe to the API you want to use. Once subscribed, go to your Profile, open the Subscription section, and select the specific API. Your API key will be available there and can be used to authenticate your requests.
You can’t switch APIs during the free trial. If you subscribe to a different API, your trial will end and the new subscription will start as a paid plan.
If you don’t cancel before the 7th day, your free trial will end automatically and your subscription will switch to a paid plan under the same plan you originally subscribed to, meaning you will be charged and gain access to the API calls included in that plan.
The free trial ends when you reach 50 API requests or after 7 days, whichever comes first.
No, the free trial is available only once, so we recommend using it on the API that interests you the most. Most of our APIs offer a free trial, but some may not include this option.
Yes, we offer a 7-day free trial that allows you to make up to 50 API calls at no cost, so you can test our APIs without any commitment.
Zyla API Hub is like a big store for APIs, where you can find thousands of them all in one place. We also offer dedicated support and real-time monitoring of all APIs. Once you sign up, you can pick and choose which APIs you want to use. Just remember, each API needs its own subscription. But if you subscribe to multiple ones, you'll use the same key for all of them, making things easier for you.
