How this service works
Pay-per-call web and domain utilities for AI agents: URL to Markdown, link preview metadata, links, uptime/redirect check, DNS, email-domain check, WHOIS/RDAP, robots.txt and a one-call domain report. x402 (USDC on Base), no API key, no signup.
Output
Returns a JSON object containing the total link count, an array of link objects (each with url, anchor text, and internal boolean), plus separate counts of external and internal links found on the page.
Example use cases
SEO outbound link audit
“Go to https://mybrand.com/about and extract all the external links so I can audit where we're sending traffic.”
Research resource link harvesting
“Pull every link from https://en.wikipedia.org/wiki/Artificial_intelligence — I only want the external ones so I can see what sources they cite.”
Internal site navigation mapping
“Extract only the internal links from https://docs.myproduct.io/getting-started so I can map out the documentation navigation structure.”
Technical details
Endpoint
GEThttps://northline-webkit.northline-c86.workers.dev/v1/url/links?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a structured, machine-readable list of all hyperlinks on a specific public webpage, especially when you want to filter by internal vs external links and get anchor text alongside URLs. It is ideal for one-shot link audits, SEO analysis, and reference harvesting without requiring an API key or subscription — just pay $0.002 USDC per call via x402.
Side effects
- Invalid or unreachable URL returns an error response
- Private or localhost URLs are rejected (only public http/https URLs accepted)
- Pages with heavy JavaScript rendering may yield incomplete link extraction
- Payment failure (insufficient USDC balance) blocks the request via x402
- Rate limiting or timeouts on slow-loading pages may produce partial results
