Open Graph Checker & Structured Data Extractor

Structured data for AI agents

AI agents often need to extract specific facts from web pages — product names, prices, company info, article metadata — without parsing free-form text. Structured data (JSON-LD, OpenGraph, meta tags) is already machine-readable: it's designed for crawlers and can be consumed directly by agents. A page with proper schema tells your agent exactly what a product costs, who the organization is, or what the article is about, in a predictable format.

The Context.dev HTML API fetches raw HTML from any URL. Parse it for application/ld+json scripts, og:tags, and meta tags — or use this tool to inspect what's available. Combine with the Sitemap API to discover product or pricing pages, then the Markdown API for full content when structured data isn't enough.

What is structured data?

Structured data is markup that describes a page's content in a format search engines and other systems understand. Common types include JSON-LD (JavaScript Object Notation for Linked Data) — schema.org types like Product, Organization, Article — OpenGraph tags (used by Facebook, LinkedIn, and others for link previews), Twitter Cards, and standard meta tags (description, keywords, canonical). Together they tell crawlers what the page is about and how to display it in search results and social feeds.

Why does structured data matter for SEO?

Search engines use structured data to understand content and enable rich results — product stars, FAQ accordions, breadcrumbs, event dates. Pages with valid schema are more likely to earn these enhancements, which can improve click-through rates. Structured data also helps with voice search and knowledge panels. Even when it doesn't trigger rich results, it gives search engines clearer signals about your content.

Common use cases

• Auditing your site's schema for SEO or migration
• Extracting product, pricing, or organization data for agents or scripts
• Checking how your links appear when shared on social platforms
• Debugging rich results in Google Search Console
• Building datasets from public websites with consistent schema
