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). # README ## 🔗 URL Health Checker Bulk-check HTTP status codes, redirects, SSL validity, and response times for thousands of URLs. No browser, no API keys — fast and cheap monitoring. ### Store Quickstart Start with the **Quickstart** template (4 demo URLs including 404/500 cases). Once validated, switch to **SEO Link Audit** for crawl-style batches, or **Webhook Alert** for operational monitoring. ### Key Features - ⚡ **Bulk checking** — Process up to 1,000 URLs per run with configurable concurrency (1-20) - 🔁 **Redirect chain tracking** — Full 301/302/307/308 redirect path from source to final URL - ⏱ïļ **Response time measurement** — Millisecond-precision timing per URL - 🔒 **SSL validation** — Detects invalid, expired, or mismatched SSL certificates - 🏷ïļ **Error classification** — TIMEOUT, DNS_RESOLUTION_FAILED, CONNECTION_REFUSED, SSL_ERROR - 🊝 **Webhook delivery** — Send results to Slack, Discord, or any custom endpoint ### Use Cases | Who | Why | |-----|-----| | **SEO agencies** | Audit client sites for broken links, slow pages, and SSL issues in bulk | | **DevOps teams** | Schedule daily URL health checks and alert via webhook on failures | | **Migration projects** | Verify every old URL redirects correctly after a domain migration | | **API health monitors** | Track endpoint availability and response times across services | | **Content teams** | Find outdated outbound links in articles and documentation | ### Input | Field | Type | Default | Description | |-------|------|---------|-------------| | urls | string[] | (required) | URLs to check (max 1000) | | concurrency | integer | 10 | Parallel requests (1-20) | | timeoutMs | integer | 10000 | Request timeout in ms | | followRedirects | boolean | true | Follow HTTP redirects | | delivery | string | dataset | "dataset" or "webhook" | | webhookUrl | string | | Webhook endpoint URL | | dryRun | boolean | false | Test without saving | ### Input Example ```json { "urls": ["https://google.com", "https://github.com", "https://httpstat.us/404"], "concurrency": 10, "timeoutMs": 10000, "followRedirects": true, "delivery": "dataset" } ```` ### Output Example ```json { "url": "https://example.com", "statusCode": 200, "redirectChain": [], "finalUrl": "https://example.com", "responseTimeMs": 142, "contentType": "text/html; charset=UTF-8", "sslValid": true, "error": null, "checkedAt": "2026-04-05T12:00:00.000Z" } ``` ### FAQ **How is this different from a simple ping?** Ping only checks reachability. This actor fetches the URL over HTTP, inspects status codes, follows redirects, validates SSL, and measures response times — full production-level health checks. **Can I check URLs that require authentication?** Not in the current version. This actor uses anonymous HTTP requests. Authentication support is on the roadmap. **Will Cloudflare/WAF block this actor?** It respects robots.txt and uses normal User-Agent. For heavily protected sites, use moderate concurrency (1-5) and longer timeouts. **What counts as 'SSL valid'?** We verify certificate chain, expiry, hostname match, and trust. Self-signed or expired certs return sslValid=false with details. ### Related Actors URL/Link Tools cluster — explore related Apify tools: - [🔗 Broken Link Checker](https://apify.com/taroyamada/broken-link-checker) — Crawl websites to find broken links, 404 errors, and dead URLs. - [🔗 URL Unshortener](https://apify.com/taroyamada/url-shortener-resolver) — Expand bit. - [🏷ïļ Meta Tag Analyzer](https://apify.com/taroyamada/meta-tag-analyzer) — Analyze meta tags, Open Graph, Twitter Cards, JSON-LD, and hreflang for any URL. - [📚 Wayback Machine Checker](https://apify.com/taroyamada/wayback-machine-checker) — Check if URLs are archived on the Wayback Machine and find closest snapshots by date. ### Cost **Pay Per Event**: - `actor-start`: $0.01 (flat fee per run) - `dataset-item`: $0.003 per output item **Example**: 1,000 items = $0.01 + (1,000 × $0.003) = **$3.01** No subscription required — you only pay for what you use. # Actor input Schema ## `urls` (type: `array`): List of URLs to check (e.g. \['https://example.com', 'https://github.com']). Maximum 1000 per run. ## `concurrency` (type: `integer`): Maximum parallel requests. Higher = faster but may trigger rate limits. ## `timeoutMs` (type: `integer`): Request timeout in milliseconds. ## `followRedirects` (type: `boolean`): If true, follows redirects and reports the chain. If false, reports the first response. ## `delivery` (type: `string`): How to deliver results. ## `webhookUrl` (type: `string`): Required when delivery is 'webhook'. ## `dryRun` (type: `boolean`): If true, runs without saving results or sending webhooks. ## Actor input object example ```json { "urls": [ "https://google.com", "https://github.com", "https://httpstat.us/404", "https://httpstat.us/500" ], "concurrency": 10, "timeoutMs": 10000, "followRedirects": true, "delivery": "dataset", "dryRun": false } ``` # API You can run this Actor programmatically using our API.
