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://company-enrich.agentdiet.dev/v1/dns-recon)
Output
Returns live DNS resolution results (IPv4 and IPv6 addresses), TLS certificate metadata (issuer, expiry date, chain info), and an HTTP security header analysis including a security grade — all reflecting the domain's current live state at time of request.
Example use cases
Vendor security due diligence check
“Before we integrate with this new payments vendor, can you check the DNS setup, TLS certificate issuer and expiry, and HTTP security headers for their domain, payflow.io?”
Monitoring a competitor's SSL cert expiry
“I want to know when openai.com's TLS certificate expires and who issued it — can you pull that along with their current DNS resolution?”
Auditing own domain before launch
“We're about to launch our product — can you audit acmecorp.com for its DNS records, TLS certificate details, and give me a grade on the HTTP security headers to make sure everything looks solid?”
Technical details
Endpoint
GEThttps://company-enrich.agentdiet.dev/v1/dns-recon?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a combined DNS + TLS + HTTP security posture snapshot for a domain in a single call, particularly for OSINT investigations, vendor due diligence, pre-launch audits, or competitive recon. Prefer this over standalone DNS or SSL checkers when you want all three signals together without chaining multiple APIs.
Side effects
- Domain does not exist or fails to resolve — returns DNS error or empty resolution
- TLS handshake failure for non-HTTPS domains or misconfigured servers
- Rate limiting or timeout if the target domain is unreachable
- Invalid or malformed domain input returns a 400 validation error
- Payment not completed (HTTP 402) blocks the request
