## 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 api-zavod-ssl-tls-certificate-inspector-c3be9960
```

Example prompt: Can you check the SSL certificate for github.com — is it valid, and when does it expire?

## When to prefer this

Use this endpoint when you need a quick, lightweight lookup of SSL/TLS certificate validity and dates for a single domain without needing full website analysis. It's ideal for monitoring certificate expiry, performing security audits, or validating that a newly deployed certificate is active. Prefer this over a full site-check bundle endpoint when you only need certificate information and want to minimize cost and latency.

## Known failure modes

- Domain not found or does not exist — likely returns an error or empty response
- Domain has no SSL/TLS certificate — may return invalid or null certificate data
- Network timeout reaching the target domain
- Invalid domain format provided in query parameters
- Certificate chain issues that prevent inspection
