# SSL Certificate Info

> SSL Certificate Info is a paid API for AI agents from ssl-info.hsharmanov02.workers.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-12).

Retrieves SSL/TLS certificate details for any domain using Certificate Transparency data

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 ssl-certificate-info-e76c5685
```

Example prompt: Can you pull the SSL certificate info for example.com — I want to know who issued it, when it expires, and whether it's still valid?

## When to prefer this

Use this endpoint when you need quick, no-API-key SSL/TLS certificate intelligence for any domain, especially for one-off lookups or agent workflows that need certificate validity, issuer, and expiry data sourced from Certificate Transparency logs. It's well-suited for security audits, phishing investigation, and expiry monitoring where a per-call micro-payment model (via x402 on Base/Solana/Polygon/etc.) is acceptable and no credential setup is desired.

## Known failure modes

- Domain not found or no certificate transparency records available — returns empty or error response
- Invalid domain format input — likely returns a 4xx error
- Domain with no SSL certificate (HTTP only) — may return empty result or error
- Network timeout reaching the Certificate Transparency backend
- Rate limiting or payment failure via x402 protocol

## How this service works

SSL/TLS certificate intel for any domain via Certificate Transparency. Paid per call: $0.002 USDC on Base, Monad, Arbitrum, Optimism, Polygon, Avalanche or Solana (eip155:8453) via x402 v2. No API key.

## Output

Returns SSL/TLS certificate metadata for the queried domain, sourced from Certificate Transparency logs. Typically includes certificate issuer, subject, validity period (not-before and not-after dates), certificate serial number, and possibly Subject Alternative Names (SANs) and certificate chain details.
