How this service works
62 small, deterministic utility APIs (DNS and e-mail checks, web extraction, EVM decoding, x402 checks, IP math, JSON/CSV, hashing, conversions). No account or API key: pay per call in USDC with x402.
Output
Returns a JSON object with 'ok' status, tool name, and a 'result' containing: Open Graph data (og.image, og.title), SEO signals (seo.h1Count, seo.titleLength), the resolved URL, the full page title, and the favicon URL.
Example use cases
Link preview card generation
“I'm building a link preview for this URL — can you grab the Open Graph image, title, and favicon from https://stripe.com/ so I can display a nice card?”
SEO audit for a landing page
“Check the SEO metadata on https://linear.app/ for me — I want to know the page title, its length, and how many H1 tags are on the page.”
Verify OG tags before publishing
“Before I share this blog post, can you pull the Open Graph title and image from https://blog.example.com/my-post to make sure they're set correctly?”
Technical details
Endpoint
GEThttps://x402-toolbox.swiftbotlab.workers.dev/v1/web/metadata?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need lightweight, structured metadata extraction (OG tags, title, favicon, basic SEO signals) from a URL without requiring a full browser scrape or JavaScript rendering. It's ideal for link preview generation, SEO audits, content enrichment pipelines, and social sharing validation. It requires no API key — just a USDC micropayment per call — making it convenient for ad-hoc or agent-driven workflows.
Side effects
- Invalid or unreachable URL returns error with ok:false
- Non-HTTP/HTTPS URLs are rejected (only GET or HEAD supported)
- Pages blocking automated requests (bot protection, CAPTCHAs) may return empty or partial metadata
- Missing OG tags result in null og.image or og.title fields
- Payment failure (insufficient USDC balance) returns HTTP 402 before request is processed
- Timeout on slow-loading pages may produce incomplete results
