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://onchain-risk.agentdiet.dev/v1/tls-scanner)
Output
Returns live IPv4 and IPv6 DNS resolution results, TLS certificate details (issuer, subject, expiry date), and an HTTP security header analysis/grade for the queried domain, all fetched in real time.
Example use cases
Pre-launch security compliance check
“Before we go live, can you check stripe.com's TLS certificate details and HTTP security headers grade so I can confirm it meets our security baseline?”
Vendor security due diligence
“I need to vet a new SaaS vendor — can you pull the DNS resolution, TLS cert issuer and expiry, and security header score for salesforce.com?”
Monitor certificate expiry risk
“Our ops team is worried about cert lapses — can you inspect the TLS certificate on api.github.com and tell me when it expires and who issued it?”
Technical details
Endpoint
GEThttps://onchain-risk.agentdiet.dev/v1/tls-scanner?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need live, real-time DNS + TLS + security header intelligence for a specific domain in a single call — ideal for security audits, vendor vetting, pre-deployment checks, or OSINT workflows where you need all three layers (DNS, certificate, HTTP headers) without stitching together separate tools.
Side effects
- Domain does not exist or fails DNS resolution — returns DNS error or empty IP fields
- TLS handshake failure if domain has no HTTPS or certificate is invalid
- Timeout if the target domain is unreachable or slow to respond
- Invalid domain input (e.g. missing TLD or malformed string) — returns validation error
- Rate limiting or payment failure for the $0.01 per-call x402 payment flow
