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://mesh.agentdiet.dev/v1/domain-osint)
Output
Returns live DNS resolution results (IPv4 and IPv6 addresses), TLS certificate details including issuer and expiration date, and an HTTP security header grade reflecting the domain's security posture.
Example use cases
Vendor security due diligence check
“Before we integrate with payments.acme.com, can you check their DNS resolution, TLS cert issuer and expiry, and HTTP security grade so I can verify their security posture?”
Pre-launch SSL certificate audit
“We're about to go live with app.mybrand.com — can you confirm the DNS is resolving correctly, the TLS cert is valid and not expiring soon, and that the security headers are in good shape?”
Competitor domain security recon
“I want to understand the infrastructure security of competitor.io — pull their IPv4/IPv6 DNS records, TLS certificate details, and HTTP security header grade for me.”
Technical details
Endpoint
GEThttps://mesh.agentdiet.dev/v1/domain-osint?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, combined DNS + TLS + HTTP security audit for a single domain without assembling multiple separate tools. Ideal for security due diligence, pre-launch checks, vendor vetting, or competitive OSINT where you want certificate validity, IP resolution, and security header grading in one call.
Side effects
- Domain does not exist or fails DNS resolution — returns empty or error result
- Domain has no HTTPS/TLS configured — TLS fields absent or error
- Domain blocks automated HTTP probes — security headers may be incomplete
- Invalid or malformed domain string — validation error
- Network timeout reaching the target domain — partial or failed response
