How this service works
Pay-per-call domain, email and website intelligence for AI agents (x402, USDC on Base). Free demos under /demo/<endpoint>.
Output
A JSON object containing the checked URL, a letter grade (e.g. 'C'), a numeric score (0–100), HTTP status code, a list of findings with per-header advice and presence status, any cookie security issues, detected version leaks in headers, and whether HTTP redirects to HTTPS.
Example use cases
Pre-launch security header audit
“Before we go live with our new site at https://myapp.io, can you check its HTTP security headers and tell me the grade, score, and what headers we're missing or have misconfigured?”
Vendor security due diligence
“I'm evaluating a SaaS vendor at https://vendorportal.com — can you pull their HTTP security header report and flag any missing headers or version leaks I should be concerned about?”
Ongoing compliance monitoring
“Run a security header check on https://mybankingapp.com and tell me if it's missing a Content-Security-Policy, whether it properly redirects HTTP to HTTPS, and what our overall grade is.”
Technical details
Endpoint
GEThttps://domain-email-intel.laboutique.workers.dev/headers?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, structured security header grade and actionable findings for any public URL — especially useful for pre-launch audits, vendor assessments, or compliance checks. Prefer this over manual curl inspection when you need a scored, categorized report with per-header advice rather than raw header dumps.
Side effects
- Unreachable or invalid URL returns an error or non-200 status
- Sites with strict bot-blocking may return incomplete header data
- Paywalled or authentication-gated URLs may only reflect the login page headers
- Redirect chains may cause unexpected final URL analysis
- Rate limiting or network timeouts for slow external servers
