How this service works
Machine-payable x402 utilities for hashing, Base64, UUID generation, unit and timezone conversion, realtime crypto market data, webpage/document extraction, URL-to-Markdown, metadata, RAG ingestion and deterministic website change detection.
Output
Returns structured JSON with URL inspection results including HTTP status code, response headers, redirect chain hops, final destination URL, content type, page title, and other available metadata about the inspected resource.
Example use cases
Pre-flight link validation before publishing
“Before I publish my newsletter, can you inspect all these URLs and tell me if any of them redirect unexpectedly or return non-200 status codes? Start with https://myblog.com/article-123.”
Redirect chain audit for SEO
“I need to audit the redirect chain for https://oldsite.com/page — can you trace every hop it makes and tell me where it finally lands, plus all the HTTP status codes along the way?”
Metadata extraction for link previews
“Can you inspect https://techcrunch.com/2024/01/openai-news and pull out the page title, canonical URL, content type, and any Open Graph metadata so I can generate a link preview card?”
Technical details
Endpoint
POSThttps://x402-gateway-production-1f21.up.railway.app/url/inspect?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need lightweight, machine-payable URL inspection at $0.001 USDC per call via the x402 protocol — ideal for agents that need to check redirect chains, HTTP headers, content type, or page metadata without full content extraction. Prefer this over full scraping endpoints when you only need URL-level metadata rather than page body content.
Side effects
- URL is unreachable or times out — returns error status
- Invalid or malformed URL — schema validation error
- URL returns non-standard HTTP response — partial metadata returned
- Payment not received — x402 payment required error
- URL behind authentication wall — limited metadata returned
- DNS resolution failure for the domain — connection error
