# cloudPulsePoint SSL Certificate Checker

> cloudPulsePoint SSL Certificate Checker is a paid API for AI agents from x402.cloudpulsepoint.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-13).

Checks a site's TLS/SSL certificate validity and reports how many days remain until expiration, helping catch expired or soon-to-expire certificates before they disrupt HTTPS.

## 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 cloudpulsepoint-ssl-certificate-checker-74a6435b -d '<json body>'
```

Example prompt: Can you check whether the SSL certificate for https://mycompany.com is still valid and tell me how many days are left before it expires?

## When to prefer this

Choose this endpoint when you need a quick, targeted check of a single site's SSL/TLS certificate validity and expiry countdown, especially for pre-deployment checks, renewal reminders, or health monitoring. If you also need DNS, HTTP reachability, or domain WHOIS in the same call, prefer the combined health-snapshot endpoint instead.

## Known failure modes

- URL resolves to a private, loopback, link-local, or cloud-metadata address — returns HTTP 400 before payment
- Domain has no HTTPS or no certificate installed — returns an error or invalid status
- Malformed or non-resolvable URL — rejected with HTTP 400
- Certificate authority unreachable during inspection — may return timeout or partial result
- Site uses non-standard port or SNI configuration — may fail to retrieve certificate

## How this service works

Inspect the site's TLS/SSL certificate: whether it is currently valid and how many days remain until it expires. Use to catch soon-to-expire or already-expired certificates before they break HTTPS for visitors.

## Output

Returns whether the TLS/SSL certificate is currently valid, the expiration date, and the number of days remaining until expiry. Invalid or private/internal targets are rejected before any charge.
