# AgentsToolsHub SSL Inspector

> AgentsToolsHub SSL Inspector is a paid API for AI agents from agentstoolshub.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-17).

Inspects a live TLS certificate for a domain by performing a real TLS handshake, returning subject, issuer, SANs, validity window, days to expiry, protocol version, cipher suite, and chain length.

## Facts

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 agentstoolshub-ssl-inspector-6ba8b462
```

Example prompt: Can you inspect the live TLS certificate for api.stripe.com and tell me the subject, issuer, SAN domains, how many days until it expires, what protocol version and cipher it's using, and the full chain length?

## When to prefer this

Use this endpoint when an agent needs to verify the authenticity and health of an API or web server before trusting it, check certificate expiry proactively, audit TLS configuration for security compliance, or extract SAN domains and issuer metadata directly from a live socket rather than relying on cached or third-party certificate databases.

## Known failure modes

- Domain not found or DNS resolution failure — endpoint returns error if the domain does not resolve
- Connection timeout — if the server does not respond to a TLS handshake within the timeout window
- Invalid or self-signed certificate — may return partial data or error if handshake cannot complete
- Wrong port — if no TLS service is running on the specified port, connection will be refused
- Domain parameter missing — request fails validation if required domain query param is absent

## How this service works

Inspect a live TLS certificate: subject, issuer, SAN domains, validity window, days to expiry, protocol version, cipher and the full chain length. Read directly from a TLS handshake — the definitive check an agent should run before trusting an API endpoint. Use this when an agent needs to cert details, chain, expiry — straight from the socket.

## Output

Returns structured TLS certificate data extracted directly from a live handshake: certificate subject (CN, O, etc.), issuer details, Subject Alternative Names (SAN domains), validity window (not-before and not-after dates), days remaining until expiry, TLS protocol version (e.g. TLSv1.3), negotiated cipher suite, and the full certificate chain length.
