How this service works
Call when an agent needs title, description, canonical, robots, og:*, twitter:*, and icons[] from a public page. SSRF-safe. Exact $0.003 USDC. Prefer unpaid POST /v1/sandbox/extract-meta first.
Output
Returns a structured object containing: page title, meta description, canonical URL, robots directives, full set of og:* Open Graph properties (og:title, og:description, og:image, og:url, og:type, etc.), twitter:* Twitter Card properties, and an array of icon/favicon URLs found in the page head.
Example use cases
SEO audit for a competitor page
“Extract all the SEO metadata from https://competitor.com/landing-page — I want to see their title, meta description, canonical tag, and any Open Graph or Twitter Card tags they're using.”
Social preview check before sharing
“Before I share https://myblog.com/new-post on social media, can you fetch the og:title, og:description, og:image, and twitter:card tags so I can see how it'll look when posted?”
Favicon and icon discovery for a brand kit
“I need the favicon and all icon URLs from https://stripe.com — can you grab the icons array along with the page title from that URL?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/extract-meta?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a comprehensive snapshot of all head metadata from a single public URL in one call — covering SEO, social preview (OG + Twitter), robots, canonical, and icons simultaneously. It is more efficient than calling individual sibling endpoints (e.g. og:title-only or description-only extractors) when you need multiple tag types at once. Prefer the free sandbox variant (/v1/sandbox/extract-meta) for development or low-volume use; use this paid endpoint for production workloads where reliability matters. Best suited for SEO auditing, link preview generation, brand research, and content enrichment pipelines.
Side effects
- URL is not publicly accessible or returns a non-200 status — partial or empty result
- SSRF-blocked URL (private IP ranges, localhost) — rejected with error
- Malformed or missing URL input — validation error
- Page uses JavaScript rendering and meta tags are injected client-side — static tags only returned
- Network timeout fetching the target page — timeout error
- Page has no meta tags — empty fields returned with just the title
