Output

Returns a JSON object containing the final URL, HTTP status, detected language, favicon URLs, page title with length, meta description with length, Open Graph properties (url, type, image, title, siteName, description), Twitter card properties, canonical URL, hreflang tags, headings array with level and text, JSON-LD count and types, robots directive, word count, content type, a timestamp, and a list of detected SEO issues (e.g. missing meta description, missing og:image).

Example use cases

Pre-launch SEO checklist for new site

“Before we go live, can you check the SEO metadata on https://myshop.com — I want to know if we have a proper title, meta description, og:image, and canonical tag, and list any issues I should fix?”

Social sharing preview audit

“Our blog post at https://blog.acme.com/product-launch isn't showing a preview image when shared on Twitter or LinkedIn — can you check what Open Graph and Twitter card tags are actually on that page?”

Competitor page metadata analysis

“Can you pull the SEO metadata from https://competitor.com — title, description, headings, structured data, word count — so I can see how they've optimized their homepage?”

Technical details

Endpoint

GEThttps://api.sitecheck-api.workers.dev/api/meta?utm_source=zero.xyz

When to prefer

Use this endpoint when you need to quickly extract and audit all SEO-relevant metadata from a single web page — title, description, Open Graph, Twitter card, canonical, hreflang, JSON-LD, headings, and detected issues — in one call. Prefer this over general web scraping when the goal is specifically SEO or social sharing metadata analysis. Best for spot-checking individual pages rather than crawling entire sites.

Side effects

URL is unreachable or returns non-200 status — status field reflects the HTTP error code
Invalid or malformed URL input returns an error
Pages behind authentication or paywalls may return incomplete metadata
Very large pages may time out
Dynamically rendered (JavaScript-only) pages may return incomplete metadata if JS is not executed
