## 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 gocreative-ssl-certificate-lookup-7c2e97ae
```

Example prompt: Can you look up the SSL certificate details for stripe.com — I want to see the issuer, expiration date, and any subject alternative names?

## When to prefer this

Use this endpoint when you need to programmatically inspect live SSL/TLS certificate details for any domain without maintaining your own scanning infrastructure. Ideal for security audits, certificate expiry monitoring, compliance checks, or enriching domain data with certificate metadata. Pay-per-call pricing ($0.005 USDC) makes it cost-effective for on-demand lookups without a subscription.

## Known failure modes

- Domain does not have an SSL certificate — returns empty or error response
- Domain is unreachable or DNS resolution fails — connection timeout or lookup error
- Invalid domain format supplied — validation error
- Certificate is self-signed or uses a private CA — partial data returned
- Rate limiting or payment failure — HTTP 402 or 429 response

## How this service works

Keyless, pay-per-call compliance & regulated-data API for AI agents — OFAC wallet + sanctions/PEP + KYB screening, SEC filings, FRED economics, FDA recalls, federal awards, plus continuous monitoring. USDC on Base/Solana via x402, native MCP. No API key, no signup.

## Output

Returns SSL/TLS certificate metadata for the queried domain, including the issuer (certificate authority), subject, validity window (not-before / not-after dates), subject alternative names (SANs), and certificate chain details.
