How this service works
Title, description, canonical URL, language, author, published and modified dates, favicon, RSS and Atom feeds, Open Graph and Twitter card tags, JSON-LD structured data and the h1/h2 outline of a public web page.
Output
A JSON object containing: page title, meta description, canonical URL, language code, author, published and modified timestamps, favicon URL, list of RSS/Atom feed URLs, Open Graph properties (image, title, description, etc.), Twitter card tags, an array of JSON-LD structured data objects, and the h1/h2 heading outline of the page.
Example use cases
SEO audit of a competitor page
“Grab all the metadata from https://stripe.com/ — I want to see the title, meta description, canonical URL, Open Graph tags, JSON-LD, and the h1/h2 heading structure for an SEO comparison.”
Finding a site's RSS feed
“Can you check https://martinfowler.com/ and tell me if it has any RSS or Atom feeds listed in the page metadata?”
Article authorship and publish date check
“I need to verify who wrote the article at https://www.theverge.com/2024/1/1/example-article and when it was published — can you pull the author, published date, and modified date from the page metadata?”
Technical details
Endpoint
GEThttps://web.kagurazaka.dev/v1/metadata?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need rich structured metadata from a public web page without full content extraction — ideal for SEO analysis, feed discovery, link preview generation, content enrichment, or verifying Open Graph/JSON-LD markup. Prefer it over full-page scrapers when you only need metadata fields rather than body content, and over DNS/link tools when the goal is page-level semantic information rather than network or link structure.
Side effects
- Non-HTTPS or private URLs return an error or empty response
- Pages behind authentication or paywalls cannot be accessed
- Heavy JavaScript-rendered pages may return incomplete metadata if content is client-side only
- Invalid or malformed URLs cause a request validation error
- Timeout errors for very slow or unresponsive servers
- Pages with no structured metadata return empty arrays for feeds, JSON-LD, and Open Graph fields
