## Pricing

from $0.0015 / host checked

This Actor is paid per event. You are not charged for the Apify platform usage, but only a fixed price for specific events.
Since this Actor supports Apify Store discounts, the price gets lower the higher subscription plan you have.

## 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 Expiry Checker — Bulk

**Check SSL/TLS certificates for a list of domains** — issuer, validity dates, days to expiry, covered hostnames and chain problems — so you catch expiring certificates before they cause an outage. Run it on a schedule and monitor every domain you own.

### What it does

- Connects to each host and reads its **certificate**: issuer, subject, valid-from/to.
- Computes **days to expiry** and flags certs **expiring soon** or already expired.
- Reports whether the chain is **valid/trusted** and lists the SAN hostnames.

### Use cases

- **Ops & SRE** — monitor cert expiry across all domains; prevent outages.
- **Agencies / MSPs** — track certificates for many client sites at once.
- **Security** — audit TLS validity and coverage in bulk.

### Input

```json
{ "hosts": ["apify.com", "api.yoursite.com"], "port": 443, "warnDays": 30 }
```

| Field | Type | Description |
|---|---|---|
| `hosts` | array | Domains/hosts to check. |
| `port` | integer | TLS port (default 443). |
| `warnDays` | integer | Flag certs expiring within this many days. |

### Output

```json
{ "host": "apify.com", "issuer": "Let's Encrypt", "validTo": "2026-11-01T00:00:00.000Z", "daysLeft": 77, "expiringSoon": false, "valid": true }
```

#### Output schema

| Field | Type | Description |
|---|---|---|
| `host` | string | The domain checked. |
| `issuer` | string | Certificate issuer. |
| `daysLeft` | integer | Days until expiry. |
| `valid` | boolean | Whether the certificate is currently valid and trusted. |

### FAQ

**Can I get alerted?** Run it on a schedule and use a webhook/integration to alert when `expiringSoon` is true.

**Can I automate it?** Yes — via [integrations on the Apify platform](https://apify.com/integrations) and the [Apify API](https://docs.apify.com/api/v2).

### Notes

Original clean-room implementation.

# Actor input Schema

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

Domains to check (with or without https://). One certificate report per host.

## `port` (type: `integer`):

TLS port to connect on.

## `warnDays` (type: `integer`):

Flag certificates expiring within this many days as expiringSoon.

## Actor input object example

```json
{
  "hosts": [
    "yoursite.com",
    "api.yoursite.com"
  ],
  "port": 443,
  "warnDays": 30
}
```

# Actor output Schema

## `results` (type: `string`):

The results as dataset items.

# 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": [
        "apify.com",
        "example.com",
        "badssl.com"
    ]
};

// Run the Actor and wait for it to finish
const run = await client.actor("hipersoft/ssl-cert-expiry-check").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": [
        "apify.com",
        "example.com",
        "badssl.com",
    ] }

# Run the Actor and wait for it to finish
run = client.actor("hipersoft/ssl-cert-expiry-check").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 '{
  "hosts": [
    "apify.com",
    "example.com",
    "badssl.com"
  ]
}' |
apify call hipersoft/ssl-cert-expiry-check --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,hipersoft/ssl-cert-expiry-check"
        }
    }
}

```

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).
