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://github-audit.agentdiet.dev/v1/osint)
Output
Returns live DNS resolution results (IPv4/IPv6 addresses), TLS certificate details (issuer, expiry date, validity), and an HTTP security header grade/analysis for the queried domain
Example use cases
Vendor security due diligence check
“Before we integrate with this vendor, can you check openai.com's TLS certificate details, who issued it, when it expires, and how their HTTP security headers are graded?”
Monitor competitor domain infrastructure
“Can you pull a security recon on stripe.com — I want to know its current DNS IPs, TLS cert issuer and expiry, and overall HTTP security grade?”
Pre-launch security audit for a new domain
“We're launching newproduct.io next week — can you audit its DNS resolution, TLS certificate validity, and security headers to make sure everything looks solid before go-live?”
Technical details
Endpoint
GEThttps://github-audit.agentdiet.dev/v1/osint?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, combined OSINT snapshot of a domain's DNS, TLS, and HTTP security posture in a single call. Ideal for due diligence on third-party vendors, pre-deployment security checks, or competitive infrastructure reconnaissance. Prefer this over manual dig/curl approaches when you need structured, machine-readable output covering DNS + TLS + security headers together at low cost ($0.01/call).
Side effects
- Domain does not exist or fails DNS resolution — returns empty or error result
- Domain has no TLS certificate (HTTP-only) — TLS fields may be null or indicate absence
- Network timeout if target domain is unreachable or slow to respond
- Invalid domain string provided — returns validation error
- Domain exists but has no IPv6 record — IPv6 field may be empty
