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/tls-scanner)
Output
Returns live IPv4/IPv6 DNS resolution results, TLS certificate metadata (issuer, expiry date, chain details), and an HTTP security header assessment/grade for the target domain.
Example use cases
Pre-launch security posture check
“Before we go live, can you scan newproduct.example.com and tell me if the TLS cert is valid, who issued it, when it expires, and whether the HTTP security headers look solid?”
Competitor domain OSINT recon
“I need a quick OSINT snapshot of openai.com — pull the DNS IPs, TLS certificate issuer and expiry date, and give me the HTTP security header grade.”
Incident response cert expiry triage
“Our monitoring flagged a possible cert issue on api.acmecorp.io — can you check the TLS certificate right now and tell me the expiry date, issuer, and current DNS resolution?”
Technical details
Endpoint
GEThttps://json-repair.agentdiet.dev/v1/tls-scanner?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a combined DNS + TLS + HTTP security header snapshot for a domain in a single call, especially for OSINT recon, security audits, compliance checks, or verifying certificate health without setting up dedicated monitoring tooling.
Side effects
- Domain does not exist or fails DNS resolution — returns error or empty DNS fields
- Domain has no HTTPS/TLS — certificate fields will be absent or null
- Target server times out or is unreachable — partial or failed response
- Invalid domain format input — returns validation error
- Domain blocks automated probes — may return incomplete header data
