How this service works
Fetch a public https URL and extract HTML head metadata ($0.005 USDC via x402). https only — http, file, data, localhost, and private IPs are rejected. Caps: 1 MB body, ~10s timeout, max 5 redirects. Returns JSON { url, final_url, content_type, title?, description?, canonical?, lang?, open_graph, twitter, warnings }.
Output
Returns a JSON object containing the final resolved URL, content type, page title, meta description, canonical URL, language code, Open Graph metadata (og:title, og:description, og:image, etc.), Twitter card metadata, and any warnings (e.g. redirect notices, missing tags).
Example use cases
Social preview card enrichment
“I'm building a link-sharing feed — can you pull the Open Graph title, description, and image URL from https://techcrunch.com/2024/05/01/openai-gpt-5/ so I can render a preview card?”
SEO metadata audit
“Check what meta title, description, and canonical URL are set on https://mystore.com/products/widget — I want to know if the SEO metadata looks correct.”
Automated link unfurling in chat
“A user just pasted https://github.com/openai/openai-python into the chat — grab its page title, description, and og:image so I can show a nice unfurl preview.”
Technical details
Endpoint
POSThttps://well-006-url-metadata.mmelnyk2000.workers.dev/mcp?utm_source=zero.xyz#url-metadata#url-metadataWhen to prefer
Choose this endpoint when you need structured HTML head metadata (title, description, Open Graph, Twitter cards, canonical, lang) from a single public HTTPS URL without writing custom scraping logic. Ideal for link preview/unfurling, SEO audits, and metadata enrichment pipelines. Prefer this over a full web scraper when you only need head-level metadata, not page body content.
Side effects
- Non-HTTPS URLs (http, file, data, localhost, private IPs) are rejected with an error
- Response body exceeds 1 MB cap — truncated or rejected
- Request times out after ~10 seconds for slow servers
- More than 5 redirects causes failure
- URL is unreachable or returns a non-200 status
- Content-Type is not HTML — metadata fields may be absent or minimal
