Example use cases
Link preview card generation
“Grab the title, meta description, OpenGraph image, and favicon for https://techcrunch.com/2024/05/01/some-article so I can show a rich link preview to my users.”
RSS feed discovery for a blog
“Check https://paulgraham.com/articles.html and tell me what RSS or Atom feeds are available on that page — I want to subscribe to it automatically.”
SEO audit of competitor landing page
“Fetch the SEO metadata from https://www.notion.so — I need the page title, meta description, and OpenGraph tags to compare against our own landing page.”
Technical details
Endpoint
GEThttps://devx-x402-tools.nextill-pos.workers.dev/v1/web/meta?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need lightweight link/SEO metadata (title, description, OG tags, favicon, feeds) for a URL without paying for a full Markdown page fetch. It is cheaper ($0.001 vs $0.002) than the full web-reader endpoint and ideal for link preview generation, feed discovery, and SEO audits. Requires no API key or signup; payment is per-call in USDC on Base via x402.
Side effects
- Invalid or malformed URL returns an error without charging
- Upstream site is unreachable or times out — not charged
- Site blocks headless fetches (403/429) — HTTP status reflected in response
- URL resolves to non-HTML content (e.g. PDF) — may return partial or empty metadata
- Redirect loops cause resolution failure — not charged
