## 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 yruz-ssl-lookup-8c06f883 -d '<json body>'
```

Example prompt: Can you look up the SSL certificate details for github.com on port 443 and tell me when it expires and who issued it?

## When to prefer this

Use this endpoint when you need a quick, lightweight programmatic SSL certificate lookup for any hostname and port without setting up local TLS inspection tooling. Suitable for automated certificate expiry monitoring, security audits, or pre-deployment checks within agent workflows.

## Known failure modes

- Host unreachable or DNS resolution failure — empty or error result
- Invalid hostname format — request rejected
- Port not open or connection refused — timeout or error
- Self-signed or untrusted certificate may still return data but flagged
- No SSL/TLS listener on specified port — connection error
