How this service works

Extract static page metadata and share previews from one public HTML URL: title, description, canonical candidates, Open Graph/Twitter fields, image and favicon references. Resolve relative links, disclose canonical conflicts and apply explicit precedence. Maximum 1 MiB HTML and five redirects. No JavaScript rendering, asset retrieval or reachability guarantee for linked images.

Output

Returns a JSON object with the resolved page title, meta description, canonical URL, canonical candidates array, a boolean flag for canonical conflicts, Open Graph fields as key-value arrays, Twitter card fields, a list of image URLs, a list of favicon/icon URLs, the retrieval timestamp, the original URL, status, and a list of applicable parsing limitations.

Example use cases

Social share preview before posting

“Before I post this link to our Slack channel, can you fetch the preview metadata from https://example.com/blog/our-big-announcement — I want to see the title, description, and the og:image that will show up in the unfurl?”

SEO canonical URL audit

“Check the page at https://www.myshop.com/products/blue-widget for me — I need to know what canonical URL is declared, whether there are any canonical conflicts, and what all the canonical candidates are in the HTML.”

Link enrichment for content aggregator

“I'm building a reading list and need the metadata for this article at https://arstechnica.com/science/2024/03/new-discovery/ — grab the title, meta description, Open Graph type, and any images referenced so I can populate the card.”

When to prefer

Choose this endpoint when you need to quickly extract static HTML metadata (title, description, OG tags, Twitter cards, canonical URL, images, favicon) from a single public webpage without needing JavaScript execution, full asset downloading, or content body extraction. It is ideal for link preview generation, SEO audits of canonical declarations, social share enrichment, and content aggregation card population. Prefer alternatives if you need rendered page content, JavaScript-dependent metadata, full page text extraction, or asset reachability verification.
