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://domain-osint.agentdiet.dev/v1/dns-recon)
Output
Returns live DNS resolution results (IPv4/IPv6 addresses), TLS certificate metadata (issuer, expiry date), and an HTTP security header grade for the queried domain, as a structured JSON object.
Example use cases
Pre-launch security audit for new domain
“Before we go live, can you check openai.com's DNS resolution, TLS certificate issuer and expiry, and HTTP security header grade so I can see if anything looks misconfigured?”
Competitor infrastructure OSINT
“I want to do a quick recon on stripe.com — can you pull its IPv4 and IPv6 DNS records, TLS certificate details, and HTTP security grade?”
SSL expiry monitoring check
“Can you check when the TLS certificate for shopify.com expires and who issued it? I want to make sure it's not about to lapse.”
Technical details
Endpoint
GEThttps://domain-osint.agentdiet.dev/v1/dns-recon?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a single, unified lookup combining DNS resolution, TLS certificate inspection, and HTTP security header grading for a domain in one call. Ideal for security audits, OSINT investigations, infrastructure reconnaissance, and pre-launch compliance checks where you need live data rather than cached or passive records.
Side effects
- Domain does not exist or fails to resolve — DNS lookup returns empty or NXDOMAIN
- Domain is unreachable or times out during live TLS handshake — certificate data unavailable
- Domain has no HTTPS endpoint — TLS certificate and security header fields may be absent or null
- Malformed domain input (e.g. missing TLD, spaces) — likely returns validation error
- Rate limiting or payment failure — HTTP 402 returned if payment not provided
