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-bcc8ee2d
```

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

## When to prefer this

Choose this endpoint when you need quick, pay-per-call SSL certificate inspection for a single hostname without managing your own TLS scanning infrastructure. Prefer it for ad-hoc audits, pre-deployment checks, or agent workflows that need certificate expiry and issuer data on demand. If you also need DNS and RDAP data alongside TLS info, consider the sibling 'Hostname dossier' endpoint instead.

## Known failure modes

- Hostname does not exist or is unreachable — connection error returned
- Domain has no SSL/TLS certificate configured — error or empty result
- Certificate is self-signed or uses an untrusted CA — may still return data but flagged
- Invalid hostname format provided — argument/validation error
- Missing required arguments — call settles as billed per API terms
- Timeout if remote server is slow to respond on port 443
