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://whale-momentum.agentdiet.dev/v1/ssl-audit)
Output
Returns live DNS resolution results (IPv4 and IPv6 addresses), TLS certificate metadata including issuer and expiration date, and an HTTP security header grade/score reflecting the presence or absence of headers like HSTS, CSP, X-Frame-Options, and others.
Example use cases
Pre-launch security posture check
“Before we go live, can you audit our domain acme-startup.com for DNS resolution, TLS certificate details, and HTTP security headers so we know if anything looks misconfigured?”
Competitor domain security benchmarking
“I want to understand how shopify.com stacks up on security — can you pull their TLS cert info, DNS records, and HTTP security grade so I can compare it against our own setup?”
Expiring certificate alert investigation
“We got an alert that one of our domains might have an expiring cert — can you check api.mycompany.com and tell me the TLS certificate issuer, expiry date, and current security header grade?”
Technical details
Endpoint
GEThttps://whale-momentum.agentdiet.dev/v1/ssl-audit?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a combined, single-call view of a domain's DNS posture, TLS certificate health, and HTTP security header configuration. It is ideal for security OSINT, pre-launch audits, or monitoring third-party domains. Prefer this over separate DNS or certificate tools when you want all three data points (DNS, TLS, security headers) in one response at a low per-call cost of $0.01.
Side effects
- Domain does not exist or fails DNS resolution — returns error or empty DNS results
- Target domain has no TLS certificate (HTTP-only) — TLS fields may be null or error
- Domain is unreachable or times out — endpoint may return a timeout or connectivity error
- Invalid or malformed domain input — returns validation error
- Rate limiting or payment failure — HTTP 402 response requiring payment
