Frequently Asked Questions

        
Everything you need to know about LinkMeta.

      

      

        

          Is LinkMeta really free?
          
Yes, completely free. No API keys, no authentication, no rate limits, no pricing tiers. LinkMeta is open-source and free to use for any purpose — personal projects, commercial applications, or enterprise tools. Free forever.

        

        

          What metadata does the API extract?
          
LinkMeta extracts 20+ metadata fields including Open Graph tags (title, description, image, type, locale, site name), Twitter Card data, favicons, JSON-LD structured data, canonical URLs, author information, publish dates, keywords, and theme colors.

        

        

          How fast is the API?
          
Average response time is under 200ms. Cached responses are served instantly. The API includes built-in caching with configurable TTL, so repeat requests for the same URL are extremely fast.

        

        

          Can I extract metadata from multiple URLs at once?
          
Yes! Use the batch endpoint (POST /api/v1/batch) to extract metadata from up to 10 URLs in a single request. Send a JSON body with an array of URLs and receive all metadata at once.

        

        

          Is there a rate limit?
          
No. There are no rate limits. You can make as many requests as you need. The built-in caching system ensures the API stays fast and responsive even under heavy load.

        

        

          What programming languages are supported?
          
LinkMeta is a REST API that returns JSON. It works with any programming language that can make HTTP requests — JavaScript, Python, PHP, Go, Ruby, Java, C#, Rust, and more. Check the documentation for code examples.
