## Pricing

from $4.90 / 1,000 domain auditeds

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 a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases.
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.

In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md):

```bash
npm install apify-client
```

In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md):

```bash
pip install apify-client
```

In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md):

````bash
# MacOS / Linux
curl -fsSL https://apify.com/install-cli.sh | bash
# Windows
irm https://apify.com/install-cli.ps1 | iex
```bash

In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md).

If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md).

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

For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt).

### Store Positioning

**Store title:** TLS Certificate Monitor

**Short description:** Monitor TLS certificates, expiry, chain health, issuer changes, and HTTPS readiness.

**SEO title:** TLS Certificate Monitor — technical SEO, web, and domain audit

**SEO description:** Monitor TLS certificates, expiry, chain health, issuer changes, and HTTPS readiness. Use it to find crawlability, indexability, security, metadata, and page-quality issues with evidence-backed rows and audit reports.

### Fixed-Inclusive PPE Pricing

This actor uses pay-per-event pricing. Event prices include Apify platform usage; users are not expected to pay a separate platform-usage pass-through charge for the configured pricing model.

- Tier: W1 — Web/domain audit
- Primary event: `domain-audited` at $0.00490 base
- Default max charge: $10.00
- Store discounts: FREE/BRONZE base, SILVER discounted, GOLD deepest approved discount

Event set:

- `actor-start`: base $0.00500, GOLD $0.00400. Tls Certificate Monitor: charged when actor start is completed. The price includes Apify platform usage; no separate usage pass-through is intended.
- `domain-audited`: base $0.00490, GOLD $0.00392. Tls Certificate Monitor: charged when domain audited is completed. The price includes Apify platform usage; no separate usage pass-through is intended.
- `record-extracted`: base $0.00372, GOLD $0.00298. Tls Certificate Monitor: charged when record extracted is completed. The price includes Apify platform usage; no separate usage pass-through is intended.
- `finding-emitted`: base $0.00372, GOLD $0.00298. Tls Certificate Monitor: charged when finding emitted is completed. The price includes Apify platform usage; no separate usage pass-through is intended.
- `audit-report-generated`: base $0.05000, GOLD $0.04000. Tls Certificate Monitor: charged when audit report generated is completed. The price includes Apify platform usage; no separate usage pass-through is intended.

### Public Task Concepts

- Compare previous and current TLS Certificate snapshots
- Monitor TLS Certificate changes for a capped watchlist
- Build a TLS Certificate change digest from supplied evidence
- Prioritize high-impact TLS Certificate changes
- Export TLS Certificate change rows for client review

### What It Does

Monitor TLS certificates, expiry, chain health, issuer changes, and HTTPS readiness.

Monitor TLS certificates, expiry, chain health, issuer changes, and HTTPS readiness. Use it to find crawlability, indexability, security, metadata, and page-quality issues with evidence-backed rows and audit reports.

### What It Does Not Do

- It does not bypass authentication, access private systems, or perform invasive security testing.
- It does not make unbounded crawls or unbounded external requests.
- It does not replace a full compliance, legal, or security assessment.
- It does not publish itself or change live Apify Store settings; release actions stay behind the repository scheduler and cloud replay gates.

### Input Fields

- `targets`
- `hostnames`
- `checkLive`
- `comparePrevious`
- `warningDays`
- `criticalDays`
- `maxItems`
- `maxTargets`
- `connectionTimeoutMs`
- `includeReport`
- `dryRun`
- `debug`

### Example Input

```json
{
  "checkLive": false,
  "comparePrevious": true,
  "warningDays": 30,
  "criticalDays": 14,
  "maxTargets": 2,
  "includeReport": true
}
````

### Output Fields

- `monitorId`
- `sourceType`
- `sourceId`
- `sourceUrl`
- `hostname`
- `port`
- `status`
- `severity`
- `tlsReachable`
- `authorized`
- `authorizationError`
- `protocol`
- `cipher`
- `validFrom`
- `validTo`
- `daysUntilExpiry`
- `expiryStatus`
- `issuer`
- `subject`
- `serialNumber`
- `fingerprint256`
- `subjectAltNames`
- `chainLength`
- `addedNames`
- `removedNames`
- `changedFields`
- `issuerChanged`
- `certificateRotated`
- `changeType`
- `issueCount`
- `issues`
- `checkedAt`
- `recommendation`

### Cost Controls

- Start with the tiny example input.
- Keep caps conservative: maxItems, maxTargets, includeReport.
- Keep pass-through usage set to OFF unless a future live cost review requires a change.
- Generate reports only when the report event is configured and budget allows it.

### Public Task Examples

#### Audit public URLs for TLS Certificate Monitor issues

- Search intent: audit public urls for tls certificate monitor issues
- Expected output: Dataset rows and summary artifacts for TLS Certificate Monitor.

#### Find TLS Certificate Monitor problems across a website

- Search intent: find tls certificate monitor problems across a website
- Expected output: Dataset rows and summary artifacts for TLS Certificate Monitor.

#### Generate a technical TLS Certificate Monitor report

- Search intent: generate a technical tls certificate monitor report
- Expected output: Dataset rows and summary artifacts for TLS Certificate Monitor.

### Limitations

- Results depend on the supplied records, fixture data, or public DNS/HTTP signals available to the actor.
- Network and DNS results can differ by resolver, region, CDN, or runtime environment.
- Recommendations are operational guidance and should be reviewed before production changes.

### FAQ

#### What should I run first?

Use the bundled tiny input or a single low-risk domain/record before expanding caps.

#### Does this actor require credentials?

No credentials are required for the default bounded workflow.

#### How is billing protected?

Paid dataset rows are emitted only after the configured PPE guard accepts the relevant event charge.

# Actor input Schema

## `targets` (type: `array`):

Optional list of target snapshots or live host checks. Defaults use tiny fixture snapshots and make no network calls.

## `hostnames` (type: `array`):

Optional hostnames for live TLS checks. Used only when checkLive is true.

## `checkLive` (type: `boolean`):

When true, connect to each hostname and inspect the live certificate. Default false avoids network usage.

## `comparePrevious` (type: `boolean`):

Detect issuer, fingerprint, SAN, expiry, and protocol changes when previousCertificate is supplied.

## `warningDays` (type: `integer`):

Mark certificates expiring within this many days as warning.

## `criticalDays` (type: `integer`):

Mark certificates expiring within this many days as high-severity.

## `maxItems` (type: `integer`):

Alias for Max Targets/Maximum Records used by the Junipr actor baseline. When both are provided, actor-specific limits still apply.

## `maxTargets` (type: `integer`):

Maximum certificate targets to analyze in one run.

## `connectionTimeoutMs` (type: `integer`):

Timeout per live TLS socket connection. Used only when checkLive is true.

## `includeReport` (type: `boolean`):

Store result JSON, summary JSON, and a Markdown TLS report in the key-value store.

## `dryRun` (type: `boolean`):

Validate input and write a dry-run summary without PPE charges or dataset output.

## `debug` (type: `boolean`):

Enable verbose logs. Do not include secrets in input.
