How this service works
Inspects live IPv4/IPv6 DNS resolution, TLS certificate issuer/expiry, and HTTP security grade. (Live x402 v2, IETF MPP & MCP endpoint at https://json-repair.agentdiet.dev/v1/domain-osint)
Output
Returns a JSON object containing live DNS resolution results (IPv4 and IPv6 addresses), TLS certificate details (issuer, subject, expiry date, validity status), and an HTTP security header assessment (presence and grade of headers like HSTS, CSP, X-Frame-Options, etc.) for the specified domain.
Example use cases
Pre-vendor security due diligence
“Before we integrate with this vendor, can you audit stripe.com for me — check their DNS records, TLS certificate issuer and expiry, and HTTP security headers so I can assess their security posture?”
Certificate expiry monitoring alert
“Check whether the TLS certificate for mybusiness.com is close to expiring — I need the issuer, expiry date, and whether there are any security header issues I should know about.”
Competitor infrastructure recon
“Run a domain OSINT scan on openai.com — I want the IPv4 and IPv6 addresses it resolves to, details on their SSL certificate, and how their HTTP security headers score.”
Technical details
Endpoint
POSThttps://json-repair.agentdiet.dev/v1/domain-osint?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, consolidated security reconnaissance snapshot of a domain without running separate DNS, SSL, and header scanning tools. It is ideal for OSINT workflows, vendor due diligence, certificate expiry monitoring, or pre-engagement recon. Prefer it over general web scraping tools when you specifically need structured TLS, DNS, and HTTP security data in one call.
Side effects
- Domain does not exist or fails DNS resolution — returns an error or empty DNS fields
- Domain is unreachable or times out during TLS handshake — TLS fields may be null or error
- Domain has no HTTPS support — TLS certificate fields will be absent
- Invalid domain input (empty string or malformed) — returns validation error
- Network-level blocks or firewalls may prevent live probing — partial results returned
