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
A JSON object containing the queried domain name, HTTPS status code, security headers grade (e.g. 'A'), domain registration age in days, and an array of risk flags. Example: {domain: 'stripe.com', https: {status: 200, securityHeaders: {grade: 'A'}}, registration: {ageDays: 10000}, flags: []}
Example use cases
Third-party vendor due diligence
“Before we integrate with this new payment vendor, can you run a domain report on their site paymentco.io and tell me if there are any red flags — like a brand-new registration, bad security headers, or HTTPS issues?”
Phishing domain investigation
“I got a suspicious email from support@secure-banklogin.net — can you pull a domain report on secure-banklogin.net and tell me how old it is, what the security posture looks like, and if there are any risk flags?”
Pre-launch domain audit
“We're about to launch our new product at launchpad-app.com — can you run a domain report on it so I can confirm the HTTPS is working, security headers are solid, and there's nothing flagged before we go live?”
Technical details
Endpoint
GEThttps://northline-webkit.northline-c86.workers.dev/v1/domain/report?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a comprehensive, single-call domain intelligence report covering security, registration, DNS, and uptime — rather than calling separate endpoints for each signal. Ideal for due diligence workflows, phishing investigation, vendor vetting, or pre-launch audits. Prefer over individual DNS/WHOIS/uptime endpoints when you want a holistic domain health snapshot in one request. Pay-per-call with no API key required makes it suitable for low-volume or one-off agent tasks.
Side effects
- Invalid or non-existent domain returns an error or empty result
- Domain with no HTTPS may return null/missing https fields
- Very new domains may have incomplete WHOIS/RDAP data
- Rate limits or payment failures (x402) result in 402 Payment Required
- Network timeouts for slow or unresponsive domains
