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, published and modified dates, author, favicon URL, array of RSS/Atom feed URLs, Open Graph tags (image, title, description, etc.), Twitter card tags, JSON-LD structured data array, and the h1/h2 heading outline of the page.
Example use cases
Social preview card enrichment
“I'm building a link preview feature — can you pull the Open Graph title, description, and image from https://stripe.com/blog/payment-api-design for me?”
Article authorship and date lookup
“I need to know who wrote the article at https://www.theverge.com/2024/1/5/example-article and when it was published — can you extract that from the page metadata?”
RSS feed discovery for a site
“Can you check https://hnrss.org/ and tell me what RSS or Atom feeds are available on that page, along with its language and canonical URL?”
Technical details
Endpoint
GEThttps://q7w9tnp09rjt5ccj.68r.lambda-web.us-east-1.on.aws/v1/metadata?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need rich, structured metadata from a public web page in a single call — especially when you need Open Graph tags, JSON-LD structured data, RSS/Atom feed discovery, canonical URL, and heading outline all at once. It is ideal for link preview generation, SEO auditing, content indexing, and article metadata extraction. Prefer this over a full-page scraper when you only need metadata fields rather than body content.
Side effects
- Non-HTTPS URL provided — endpoint requires https:// URLs
- Page is behind authentication or a paywall — returns incomplete or no metadata
- URL is unreachable or returns a non-200 status — extraction fails
- Page has no Open Graph tags or JSON-LD — those fields return empty arrays or null
- Dynamic JavaScript-rendered metadata may not be captured if page requires JS execution
- Malformed or missing URL query parameter — returns validation error
