# SSL Certificate Checker API - TLS Expiry Scanner (`pink_comic/ssl-certificate-checker`) Actor

Bulk SSL/TLS certificate checker API for expiry monitoring, HTTPS audits, issuer/SAN extraction, chain validation, TLS version, and cipher-suite evidence. Scan domains for expiring, expired, or misconfigured certificates before outages or compliance reviews.

## 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 - Bulk Expiry Monitor

Check SSL/TLS certificates for any domain in bulk. Identify expired, expiring, or misconfigured certificates across your entire domain portfolio.

### What it does

For each domain, this actor connects via TLS and extracts complete certificate details including issuer, expiration, certificate chain, SANs, and negotiated protocol. Use it for:

- **Certificate expiry monitoring** — find certificates expiring in the next 30/60/90 days
- **Security audits** — verify certificate chains, signature algorithms, and TLS versions
- **Compliance checks** — ensure all domains use current TLS standards
- **Domain portfolio management** — bulk-check hundreds of domains at once
- **Vendor risk assessment** — verify SSL health of third-party services

### Input

| Field | Type | Description |
|-------|------|-------------|
| `domains` | Array of strings | Domains to check (e.g., `google.com`, `github.com`) |
| `maxResults` | Integer | Maximum domains to check (default: 100, max: 10,000) |

### Output

```json
{
  "domain": "google.com",
  "isValid": true,
  "issuer": "Google Trust Services",
  "subject": "*.google.com",
  "notBefore": "2026-03-01T00:00:00Z",
  "notAfter": "2026-05-24T00:00:00Z",
  "daysUntilExpiry": 48,
  "isExpired": false,
  "isExpiringSoon": false,
  "serialNumber": "1A2B3C...",
  "signatureAlgorithm": "SHA256-RSA",
  "subjectAlternativeNames": ["*.google.com", "google.com"],
  "certificateChain": ["*.google.com", "GTS CA 1C3", "GTS Root R1"],
  "tlsVersion": "TLS 1.3",
  "cipherSuite": "TLS_AES_128_GCM_SHA256"
}
```

### Pricing

$0.10 per 1,000 domains checked.

# Actor input Schema

## `domains` (type: `array`):

List of domains to check SSL certificates for. Enter one domain per line (e.g., google.com, github.com).

## `maxResults` (type: `integer`):

Maximum number of domains to check. Use this to control costs.

## Actor input object example

```json
{
  "domains": [
    "google.com",
    "github.com",
    "openai.com"
  ],
  "maxResults": 100
}
```

# 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 = {
    "domains": [
        "google.com",
        "github.com",
        "openai.com"
    ]
};

// Run the Actor and wait for it to finish
const run = await client.actor("pink_comic/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 = { "domains": [
        "google.com",
        "github.com",
        "openai.com",
    ] }

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

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

## CLI example

```bash
echo '{
  "domains": [
    "google.com",
    "github.com",
    "openai.com"
  ]
}' |
apify call pink_comic/ssl-certificate-checker --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,pink_comic/ssl-certificate-checker"
        }
    }
}

```

The hosted server signs you in with OAuth on first connect, so no API token belongs in this config. Clients without OAuth support can send an `Authorization: Bearer <APIFY_API_TOKEN>` header instead, using a token from API & Integrations in Apify Console (https://console.apify.com/settings/integrations).
