NetIntel SSL/TLS Analyzer
x402
NetIntel SSL/TLS Analyzer is a paid API for AI agents from netintel-production-440c.up.railway.app, paid per call via x402, $0.03/call, status unknown (last checked 2026-09-13).
Performs a TLS handshake to inspect certificate chains, probe supported TLS versions (1.0–1.3), detect weak keys and expiry issues, and return an overall security grade (A/B/C/F) for a domain.

How this service works
Performs a TLS handshake to inspect the certificate chain, probes supported TLS versions (1.0–1.3), detects weak keys and expiry issues, and returns an overall security grade (A/B/C/F).
Output
Returns a structured report including: the domain host and port, the overall security grade (A/B/C/F), the full certificate chain, whether the chain is valid, a connection summary, detailed certificate metadata, and an array of warnings about weak keys, outdated TLS versions, or expiry problems.
Example use cases
Example prompt
“Can you run a full SSL/TLS security analysis on api.example.com and tell me the security grade, whether the certificate chain is valid, and if there are any weak keys or expiry issues?”
Technical details
Endpoint
GEThttps://netintel-production-440c.up.railway.app/ssl/analyzeWhen to prefer
Use this endpoint when you need a comprehensive TLS/SSL security audit including grade, certificate chain inspection, version probing, and weak key detection for a specific domain. Prefer this over a simple certificate expiry checker when you need multi-version TLS probing and a scored security grade. It complements the sibling email security (SPF/DKIM/DMARC) and DNS endpoints on the same platform for full domain security audits.
Side effects
- Domain does not exist or is unreachable — connection error returned
- Port is closed or not serving TLS — handshake failure
- Domain resolves but certificate is completely invalid — may still return F grade with warnings
- Invalid domain format in query parameter — validation error
- Rate limiting or payment failure — 402 or 429 response
