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 strale-ssl-check-40dced1e
```

Example prompt: Can you check whether api.example.com has a valid SSL certificate and tell me if there are any issues with the certificate chain?

## When to prefer this

Choose this endpoint when you need a lightweight, auditable SSL certificate check with a cryptographic audit trail — particularly useful in agentic or compliance workflows where you need verifiable proof of the check. Prefer this over generic web-scraping or ping tools when the specific goal is certificate chain and HTTPS validity verification with structured output.

## Known failure modes

- Invalid or non-existent domain returns an error or empty certificate data
- Domains with no HTTPS configured will return connection failure
- Timeout if the target domain is unreachable or very slow to respond
- Malformed domain input (e.g. including 'https://' prefix) may cause parsing errors

## How this service works

The trust layer for AI agents — 250+ independently tested data capabilities across 27 countries. Execute capabilities via REST, MCP, A2A, or x402 micropayments. Every call returns an audit record with cryptographic chain hashing.

## Output

Returns structured JSON with SSL certificate validity status, full certificate chain details, expiry dates, issuer information, and an audit record with a cryptographic chain hash for provenance verification.
