# SSL Certificate Checker — Scout Packs / Tiger Operations

> SSL Certificate Checker — Scout Packs / Tiger Operations is a paid API for AI agents from scout-packs-production.up.railway.app, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-11).

Checks the SSL/TLS certificate status of a given domain, returning validity, issuer, expiry date, TLS version, and days remaining.

## Facts

- Price: $0.01/call

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-checker-scout-packs-tiger-operations-87462eac
```

Example prompt: Can you check the SSL certificate for acme.com — is it valid, who issued it, and how many days until it expires?

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call SSL/TLS certificate check with no account or API key setup. It is ideal for one-off audits, pre-launch checks, or agent-driven security monitoring where you want to verify certificate validity, issuer, TLS version, and days remaining for any domain on demand. Costs only $0.01 USDC per call via x402 on Base.

## Known failure modes

- Domain does not exist or is unreachable — likely returns invalid/error state
- Domain missing query parameter — request will fail validation
- Certificate is expired or self-signed — returned as valid:false with relevant signals
- Network timeout reaching the target domain — may return an error or partial result
- Invalid domain format — schema validation failure

## How this service works

Verified B2B lead packs and per-lead enrichment lookups for agents. $0.01 per lookup or pack (demand probe). USDC on Base via x402. No account, API key, or subscription.

## Output

A JSON object containing: whether the certificate is valid (boolean), the domain checked, the certificate issuer (e.g. 'Let's Encrypt'), the expiry date, TLS version (e.g. 'TLSv1.3'), days remaining until expiry, any signals or warnings, and a receipt field confirming the call.
