How this service works
Use when an agent needs to know what a URL is before reading it, or to build a link preview or citation. Input: url (public http/https). Output: JSON with final URL after redirects, HTTP status, content type, title, description, site name, language, canonical, preview image, favicon, Open Graph and Twitter tags, RSS/Atom feeds, hreflang alternates, JSON-LD types, robots, first H1. No JavaScript is run. Example: ?url=https://developer.mozilla.org/en-US/
Output
A JSON object containing: final URL after any redirects, HTTP status code, content type, page title, meta description, site name, language, canonical URL, preview image URL, favicon URL, Open Graph key-value pairs, Twitter card key-value pairs, RSS/Atom feed links, hreflang alternate links, JSON-LD types found on the page, robots meta, first H1 heading, redirect chain, and cache/notes fields. No JavaScript is executed — only static HTML is parsed.
Example use cases
Link preview card for shared URL
“I'm about to post https://openai.com/blog/gpt-4o in our Slack — can you grab the title, description, and preview image so I can build a proper link card?”
Citation metadata for research notes
“I need to cite https://www.nature.com/articles/s41586-024-07612-z in my report — pull the title, author, published date, site name, and canonical URL for me.”
Redirect chain and final destination check
“Someone sent me this suspicious short link https://bit.ly/3xYzABC — can you check where it actually resolves to, what the final URL is, and what kind of content it serves?”

Endpoint
GEThttps://1gateway.dev/v1/web/metadata?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need lightweight, structured metadata from a public URL without executing JavaScript — ideal for link previews, citation generation, redirect resolution, SEO inspection, and content-type checks. It is faster and cheaper than a full browser-based scraper and returns a rich, normalized set of fields in one call. Prefer it over full-page scrapers when you only need head-level metadata, Open Graph tags, or feed discovery rather than the full page body.
Side effects
- Private or internal IP addresses return 400 and are not charged
- URLs that return non-200 status codes still return the status but may have empty metadata fields
- Pages with no meta tags return empty/null fields for title, description, image, etc.
- Very large pages may be truncated (truncated field set to true)
- Non-HTML content types (PDF, images) return content type but minimal metadata
- Network timeouts or unreachable hosts return an error response
