# SSL/TLS Certificate Audit (`conserving_mastodon/ssl-certificate-audit`) Actor

A real TLS handshake graded A-F: days until expiry, chain validity, hostname match, protocol and cipher, issuer, SAN coverage. Expired, self-signed, and wrong-host certs each get a precise verdict. Schedule it to catch expiries early. Charged only on completed audits.

## Pricing

$150.00 / 1,000 completed audits

This Actor is paid per event. You are not charged for the Apify platform usage, but only a fixed price for specific events.

## 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/TLS Certificate Audit

**A real TLS handshake and a graded verdict, in one call.** Not an HTTP fetch that assumes the cert is fine — an actual handshake that checks the things that take sites down: days until expiry, whether the chain validates, whether the certificate matches the hostname, and the protocol and cipher negotiated.

### What you get

```json
{
  "host": "example.com",
  "grade": "A",
  "days_until_expiry": 62.4,
  "chain_valid": true,
  "hostname_match": true,
  "tls_version": "TLSv1.3",
  "issuer": "Let's Encrypt",
  "san_count": 2,
  "issues": ["Certificate is valid, trusted, and not expiring soon."]
}
```

Expired, self-signed, wrong-host, and incomplete-chain certificates each get a precise **grade F** verdict naming the exact failure, so an agent asking "is this cert OK?" gets a real answer either way.

### Use cases

- **Expiry monitoring**: schedule it against your domains; alert when `days_until_expiry` drops below your threshold. A lapsed cert is one of the most common self-inflicted outages.
- **Vendor and acquisition due diligence**: grade a target's TLS hygiene in seconds.
- **Agents verifying endpoints**: confirm a service's certificate is valid before trusting it.

### Honesty notes

- One TLS handshake to `host:443` (or the port you give); no data is sent, nothing is fetched.
- A host that will not resolve or connect reports cleanly and **you are not charged**; billing is per completed audit (a bad certificate is a completed audit — that is the finding).

# Actor input Schema

## `host` (type: `string`):

Hostname to check, optionally with a port (defaults to 443). URLs are accepted and reduced to the host.

## Actor input object example

```json
{
  "host": "example.com"
}
```

# Actor output Schema

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

Grade A-F, days until expiry, chain validity, hostname match, TLS version and cipher, issuer, SAN list, and specific issues.

# 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 = {
    "host": "example.com"
};

// Run the Actor and wait for it to finish
const run = await client.actor("conserving_mastodon/ssl-certificate-audit").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 = { "host": "example.com" }

# Run the Actor and wait for it to finish
run = client.actor("conserving_mastodon/ssl-certificate-audit").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 '{
  "host": "example.com"
}' |
apify call conserving_mastodon/ssl-certificate-audit --silent --output-dataset

```

## MCP server setup

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

```

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).
