## What's an Apify Actor?

Actors are web data automations that power AI and operations. They run on the Apify platform to scrape websites, process data, connect APIs, and automate workflows.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.
Actors are written with capital "A".

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.
The best way to integrate Actors is as follows.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

# README

## 🔒 SSL Certificate Checker — Expiry & TLS Audit

SSL Labs-style certificate inspector: paste any list of domains and get **issuer, validity dates, days-to-expiry, SANs, TLS version, cipher**, plus a **grade (A+ → F)** for every host — no API key, no proxy, no external service.

### 🚀 Quick Start

1. Click **Try for free** (or Run)
2. Paste your domains (one per line, optionally `host:port`)
3. Run — get a structured report instantly

**No input?** The Actor runs a demo batch (google.com, github.com + badssl test certs) so you see the output format immediately.

### 🔍 What you get per host

| Field | Description |
|---|---|
| `subject` / `issuer` | Certificate CN + issuer organization |
| `sanDomains` | Subject Alternative Names (all covered domains) |
| `validFrom` / `validTo` | Exact validity window |
| `daysLeft` | Days until expiry (negative = expired) |
| `expired` / `selfSigned` / `hostnameMatch` | Status flags |
| `tlsVersion` / `cipher` | Negotiated protocol & cipher suite |
| `grade` | A+ to F security grade |

### 📊 Grade scale

- **A** = 180+ days left · **B** = 90–180d · **C** = 30–90d · **D** = 7–30d · **E** = ≤7d
- **F** = expired, self-signed, or hostname mismatch

### 💡 Use cases

- **DevOps / SRE** — scheduled cert-expiry monitoring across your domain portfolio
- **Security teams** — TLS hygiene audits, misconfiguration detection
- **Compliance** — evidence for cert lifecycle reviews
- **Agencies** — batch client-domain health checks

### ⚙️ Technical notes

- Pure Python `ssl`/`socket` — zero external dependencies, works from any region
- Optional `host:port` syntax for non-standard TLS ports (8443, 465, 993…)
- Each host is checked with a 10s timeout; failures are reported per-host with the reason (DNS, timeout, refused, TLS error) — one bad host never breaks the batch

# Actor input Schema

## `hosts` (type: `array`):

List of domains to inspect (optionally host:port). Empty input runs a demo batch.

## Actor input object example

```json
{
  "hosts": [
    "google.com",
    "github.com"
  ]
}
```

# API

You can run this Actor programmatically using our API. Below are code examples in JavaScript, Python, and CLI, as well as the OpenAPI specification and MCP server setup.

## JavaScript example

```javascript
import { ApifyClient } from 'apify-client';

// Initialize the ApifyClient with your Apify API token
// Replace the '<YOUR_API_TOKEN>' with your token
const client = new ApifyClient({
    token: '<YOUR_API_TOKEN>',
});

// Prepare Actor input
const input = {
    "hosts": [
        "google.com",
        "github.com"
    ]
};

// Run the Actor and wait for it to finish
const run = await client.actor("unrivaled_fortress/ssl-certificate-checker").call(input);

// Fetch and print Actor results from the run's dataset (if any)
console.log('Results from dataset');
console.log(`💾 Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`);
const { items } = await client.dataset(run.defaultDatasetId).listItems();
items.forEach((item) => {
    console.dir(item);
});

## Python example

```python
from apify_client import ApifyClient

# Initialize the ApifyClient with your Apify API token
# Replace '<YOUR_API_TOKEN>' with your token.
client = ApifyClient("<YOUR_API_TOKEN>")

# Prepare the Actor input
run_input = { "hosts": [
        "google.com",
        "github.com",
    ] }

# Run the Actor and wait for it to finish
run = client.actor("unrivaled_fortress/ssl-certificate-checker").call(run_input=run_input)

# Fetch and print Actor results from the run's dataset (if there are any)
print("💾 Check your data here: https://console.apify.com/storage/datasets/" + run["defaultDatasetId"])
for item in client.dataset(run["defaultDatasetId"]).iterate_items():
    print(item)
