# NetIntel SSL/TLS Analyzer

> 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.

## Facts

- Endpoint: GET https://netintel-production-440c.up.railway.app/ssl/analyze
- Price: $0.03/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-13
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/netintel-production-440c-up-railway-app-f9dd7ce9
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_AxYBsqtHJ_rYl78z8jmbP

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability netintel-production-440c-up-railway-app-f9dd7ce9
```

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?

## When to prefer this

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.

## Known failure modes

- 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

## 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.
