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/osint)
Output
Returns live DNS resolution data (IPv4 and IPv6 addresses), TLS certificate metadata (issuer, expiry date, validity status), and an HTTP security headers assessment including a security grade for the target domain.
Example use cases
Vendor security due diligence check
“Before we integrate with this new payments vendor at payvendor.io, can you pull their DNS records, TLS certificate details, and HTTP security header grade so we can assess their security posture?”
Monitor competitor domain security
“Run a domain OSINT scan on openai.com for me — I want to see their current DNS IPs, who issued their TLS cert and when it expires, and what their security header grade looks like.”
Pre-launch security audit for new domain
“We just set up our new domain mybrand.com — can you check that DNS is resolving correctly on IPv4 and IPv6, our TLS certificate looks good, and our HTTP security headers pass muster?”
Technical details
Endpoint
GEThttps://json-repair.agentdiet.dev/v1/osint?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, all-in-one passive recon snapshot of a domain covering DNS, TLS, and HTTP security in a single call. It is ideal for security due diligence, vendor assessments, pre-launch audits, or monitoring a domain's certificate health without needing to integrate multiple specialized DNS/SSL tools separately.
Side effects
- Invalid or non-existent domain returns an error or empty DNS result
- Domain with no TLS certificate will have null/missing certificate fields
- Domains blocking automated probes may return incomplete header data
- Network timeouts for slow or unreachable domains
- Malformed domain input (e.g. with http:// prefix or trailing slash) may cause parsing errors
