Classify and analyze public web pages or supplied text. Extract metadata, summaries, categories, entities, and custom structured JSON from static or JavaScript-rendered content.
The API can classify text or website content, analyze web pages with AI, generate summaries and structured fields, and extract standard website metadata.
Yes. The classification endpoint accepts either a publicly accessible URL or supplied text. Provide exactly one source together with the category labels you want the API to evaluate.
Add between 2 and 50 category labels to the categories array. The API analyzes the supplied content and returns the best matching category with an explanation.
It returns the page title, an AI-generated summary, key points, requested structured fields, supporting evidence, rendering mode, processing time, and token usage.
Yes. Pass a schema object containing up to 20 field names. Each value can specify a supported data type or a concise instruction describing the information to extract.
Yes. Use render="auto" to enable browser rendering when required, render="always" to force it, or render="never" for faster processing of static pages.
The metadata endpoint can return the title, description, keywords, author, language, canonical URL, Open Graph properties, Twitter Card data, and other page metadata.
No. Only publicly accessible HTTP and HTTPS URLs are supported. Private, loopback, link-local, and other restricted network destinations are rejected for security.
Use Classify Website or Text for category assignment, Analyze Website with AI for summaries and custom structured extraction, and Extract Website Metadata for fast non-AI metadata lookup.
Subscribe to the API and include your Zyla access key in the Authorization header using the Bearer scheme. The code examples in the API documentation include the required header.
To obtain your API key, first sign in to your account and navigate to the API you want to use. From the API's Pricing section, choose a plan and complete the subscription process. Once subscribed, return to the API page and you will see your API Access Key displayed at the top of the documentation page. You can use this key 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.
The free trial lasts for 7 days and allows you to make up to 50 API requests.
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. If the API offers a free trial, you will see a "Free 7-Day Trial" option in its Pricing section. The trial lasts for 7 days and allows up to 50 API requests, enabling you to evaluate the API before subscribing to a paid plan.
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.
You can monitor your API usage through the response headers included with every request:
x-zyla-api-calls-monthly-used: Shows the total number of API requests you have used during the current billing period.
x-zyla-api-calls-monthly-remaining: Shows the number of API requests you have remaining for the current billing period.
Yes, you can cancel your subscription at any time. Simply go to the Pricing section of the API you're subscribed to and click the "Unsubscribe" button.
Please note that upgrades, downgrades, and cancellations take effect immediately. Once your subscription is canceled, access to the service will end immediately, regardless of any remaining API calls in your quota.
