How this service works
Pay-per-call page profiling and x402 endpoint diagnostics, settled in Base-mainnet USDC.
Output
Returns a JSON object containing the page title, meta description, robots meta, HTTP status code, requested and final (post-redirect) URL, canonical URL, Open Graph properties, JSON-LD type identifiers, and aggregate link counts broken down into total, internal, and external.
Example use cases
SEO metadata audit for a webpage
“Pull the title, meta description, canonical tag, and Open Graph info from https://myblog.com/post/2024-review — I want to make sure it's all set up correctly for search engines.”
Verify redirect destination of a URL
“Can you check where https://short.link/abc ends up and tell me the final URL it lands on along with its HTTP status code?”
Extract structured data types from a landing page
“Look at https://shop.example.com/products/widget and tell me what JSON-LD structured data types it uses and whether it has any Open Graph tags set.”
Technical details
Endpoint
GEThttps://proof402.15-204-209-67.sslip.io/api/page-profileWhen to prefer
Choose this endpoint when you need structured page-level metadata from a single public URL — especially title, description, Open Graph, canonical, JSON-LD types, and link counts — without running a full browser or crawler. It is well-suited for SEO audits, content enrichment pipelines, link verification, and pre-fetch intelligence for agents that need to understand a page before visiting it. Prefer it over generic scraping tools when you want normalized, schema-consistent output settled via x402 micropayments on Base.
Side effects
- Non-public or firewall-protected URLs return an error or timeout
- Malformed or non-URI input values are rejected by schema validation
- Pages requiring JavaScript rendering may return incomplete metadata
- Very slow origins may cause request timeouts
- Non-HTML responses (e.g. PDFs, images) may yield empty or partial metadata fields
