The SEO Structure Checker API is an essential tool for developers, SEO agencies, writers, and platforms that need to quickly evaluate the content structure of a website. By entering a domain, this API returns an in-depth and detailed analysis of content organization, key SEO elements, readability, and compatibility with artificial intelligence technologies.
In addition, the API indicates whether the site is easily processable by AI (AI-scrapable), which is vital for generative AI tools, virtual assistants, or smart search engines. It also includes automatic suggestions for improvement such as “add more headings” or “include informative tables.”
This API is ideal for platforms that offer automated SEO audits, content optimization services, competitor analysis, marketing report generation, or even for AI that needs to understand the logical structure of a site before interacting with it.
Thanks to its speed and the simplicity of the endpoint, it can be easily integrated into dashboards, CRMs, custom crawlers, AI browsers, or automated content platforms.
The SEO Structure Checker API transforms a domain into useful and actionable data, optimizing editorial, strategic, and search engine positioning decisions. With just one call, you have access to an accurate snapshot of any website's content.
To use this endpoint, you must specify a URL in the parameter.

The API returns detailed analysis data about a website's content structure, including key SEO elements, readability scores, AI compatibility, and improvement suggestions.
Key fields in the response include content organization metrics, SEO element scores (like headings and meta tags), readability scores, AI-scrapability status, and specific improvement recommendations.
The response data is structured in a JSON format, with sections for each analysis aspect, such as SEO elements, readability, and AI compatibility, making it easy to parse and utilize.
The primary parameter is the URL of the domain you wish to analyze. Ensure the URL is properly formatted to receive accurate results.
Typical use cases include conducting SEO audits, optimizing content for better search engine ranking, competitor analysis, and enhancing AI interactions with website content.
Data accuracy is maintained through continuous updates and validation processes, ensuring that the analysis reflects the current state of the website's content and structure.
Users can expect consistent patterns in the analysis, such as a breakdown of SEO elements, readability scores ranging from low to high, and actionable suggestions for improvement.
Users can leverage the returned data to identify weaknesses in their website's structure, implement suggested improvements, and enhance overall SEO strategies for better visibility.
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.
