## Pricing

from $0.55 / 1,000 url checkeds

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

## Bulk URL Health Checker - Status, Redirects & SSL

Check a whole list of URLs at once and get, for each one: the HTTP status, whether it is OK or broken,
the full **redirect chain** and final URL, response time, content type and length, server and security
headers, and - for https - the **TLS certificate** (issuer, validity, expiry date and days remaining).

Find broken links, unexpected redirects, slow pages and **certificates about to expire** across a site,
a sitemap, or any URL list. Pure HTTP + a TLS handshake, no browser, cents per URL.

### What you get per URL

`status` `ok` `isBroken` `reachable` · `responseTimeMs` · `finalUrl` `isRedirect` `redirectCount`
`redirectChain[]` · `contentType` `contentLength` `server` `poweredBy` `securityHeaders` `hsts` ·
`sslValid` `sslIssuer` `sslValidTo` `sslDaysRemaining` `sslError` · `error`.

### Input

```json
{
  "urls": ["https://apify.com", "example.com/old-page"],
  "checkSsl": true
}
```

- **URLs** - one per line; a bare domain gets `https://`. Leave empty for a small free sample.
- **Import URLs from a file** - paste a list, or link a public `.txt`/`.csv`, a Google Sheet/Drive
  link, or an Apify key-value-store record (e.g. pipe a sitemap's URLs straight in).
- **Check TLS/SSL** - on by default; turn off for a faster status-only run.
- **Output fields** - tick only the columns you need (e.g. just `url` + `status` + `sslDaysRemaining`).

### Notes

- Uses a light `HEAD` request (falling back to `GET` when a server rejects it), so it is fast and cheap
  even on large lists.
- A URL that does not resolve or times out is reported with `reachable: false` and the error - that is a
  valid health result, so every checked URL is counted.

### Use with AI assistants (MCP)

Available through the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp) - an agent can
monitor a set of endpoints, audit a site's links, or watch certificate expiry as part of a workflow.

### Agent-ready: autonomous payments (x402 & Skyfire)

This actor is **agent-ready** - AI agents can discover it, run it, and **pay for it autonomously**, with no Apify account and no human in the loop. It uses [pay-per-event](https://docs.apify.com/platform/actors/publishing/monetize/pay-per-event) pricing and [limited permissions](https://docs.apify.com/platform/actors/development/permissions), so it qualifies for Apify's agentic-payment standards:

- **[x402](https://docs.apify.com/platform/integrations/x402)** - an open, HTTP-native payment protocol. Agents pay per run in USDC on the Base network directly through the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp) - no account, no API key.
- **[Skyfire](https://docs.apify.com/platform/integrations/skyfire)** - agent-to-service payments for fully autonomous AI-agent workflows.

Building an AI agent, MCP tool, or autonomous data pipeline? This scraper is ready to plug in and pay as it goes.

# Actor input Schema

## `urls` (type: `array`):

URLs to check, one per line. A bare domain gets <code>https://</code>. Duplicates are collapsed. <b>Leave empty and the run returns a small free sample.</b>

## `urlsFromFile` (type: `string`):

Bulk-load URLs. Either <b>paste the whole list</b> (one per line), or give <b>a single link</b> to a public <code>.txt</code>/<code>.csv</code>, a Google Sheet/Drive share link, or an Apify key-value-store record. A file that cannot be read says so and charges nothing.

## `checkSsl` (type: `boolean`):

For https URLs, also open a TLS handshake and report the certificate issuer, validity, expiry date and days remaining. Turn off for a faster status-only run.

## `concurrency` (type: `integer`):

How many URLs to check in parallel.

## `outputFields` (type: `array`):

Pick the fields you want and every record is trimmed to exactly those. Open the dropdown and tick, or type to filter (<code>status</code>, <code>ssl</code>, <code>redirect</code>).

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

Maximum number of URLs to check in one run (after de-duplication).

## `proxyConfiguration` (type: `object`):

Optional. Checks run direct by default. Enable a proxy to check from a specific location or if a host blocks the checker.

## Actor input object example

```json
{
  "urls": [
    "https://apify.com"
  ],
  "checkSsl": true,
  "concurrency": 10,
  "maxItems": 200
}
```

# Actor output Schema

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

Each scraped record - URLs with HTTP status, redirects and TLS - as a JSON item in the default dataset.

# 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 = {
    "urls": [
        "https://apify.com"
    ],
    "urlsFromFile": ""
};

// Run the Actor and wait for it to finish
const run = await client.actor("scrapesage/url-health-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);
});

# 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 = {
    "urls": ["https://apify.com"],
    "urlsFromFile": "",
}

# Run the Actor and wait for it to finish
run = client.actor("scrapesage/url-health-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 '{
  "urls": [
    "https://apify.com"
  ],
  "urlsFromFile": ""
}' |
apify call scrapesage/url-health-checker --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,scrapesage/url-health-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).
