How this service works
Return title, description, OpenGraph card, canonical URL, feeds, favicon and detected technologies for one URL.
Output
Returns a structured object containing the page title, meta description, OpenGraph card fields (title, description, image, type, etc.), canonical URL, discovered RSS/Atom feed URLs, favicon URL, and a list of detected technologies (e.g. CMS, frameworks, analytics tools).
Example use cases
Link preview card generation
“Generate a link preview for https://www.theverge.com/2024/5/1/openai-news — grab the title, description, OpenGraph image, and canonical URL so I can display a proper card.”
Technology stack discovery
“What technologies is https://www.shopify.com built on? Pull the page metadata and tell me what frameworks, CMS, or tools are detected.”
RSS feed discovery for newsletter
“I want to follow https://simonwillison.net in my RSS reader — can you fetch the page metadata and find any available feed URLs?”
Technical details
Endpoint
POSThttps://fetch.halowerk.com/metadataWhen to prefer
Choose this endpoint when you need rich metadata about a single web page — especially for link preview generation, SEO analysis, feed discovery, or technology detection — and you want all of that in a single lightweight call rather than fetching and parsing the full page HTML yourself. Prefer this over the full article extraction endpoint when you only need metadata and not the body content, and over the batch endpoint when you only have one URL to process.
Side effects
- URL is unreachable or returns non-200 status — extraction fails with an error
- Page blocks crawlers via robots.txt or bot detection — partial or empty results
- URL is not absolute or malformed — validation error returned
- Page has no OpenGraph or meta tags — relevant fields returned as null
- JavaScript-rendered content may not be fully captured if the page requires client-side rendering
