# HTTP Status Code Checker - Bulk URLs & Redirect Chains (`dltik/http-status-checker`) Actor Bulk-check HTTP status codes and full redirect chains for any list of URLs. For each URL: final status, every redirect hop (status + Location), response time, content-type and server. Pure HTTP, reads headers only — fast and cheap. Great for SEO migrations, link audits and uptime spot-checks. - **URL**: https://apify.com/dltik/http-status-checker.md - **Developed by:** [Walid](https://apify.com/dltik) (community) - **Categories:** Developer tools, SEO tools - **Stats:** 2 total users, 1 monthly users, 100.0% runs succeeded, NaN bookmarks - **User rating**: No ratings yet ## Pricing $1.00 / 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.

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 ## HTTP Status Code Checker — Bulk URLs & Redirect Chains > ⭐ **Bookmark this actor** so bulk HTTP status checks are one click away whenever you run a migration, audit a sitemap, or vet a list of links. Check **HTTP status codes** and **full redirect chains** for any list of URLs — in bulk. For every URL you get the final status, each redirect hop (with its status and `Location`), response time, content-type and server header. It reads response **headers only** (the body is never downloaded), so it's fast, cheap, and easy on the targets. ### What it does For each URL in your list, the actor returns: - **Final HTTP status** (e.g. `200`, `301`, `404`, `500`) - **`ok`** flag (true for `2xx`/`3xx`) - **Full redirect chain** — every hop: `url`, `status`, `Location` - **Final URL** after all redirects - **Response time** in milliseconds - **content-type**, **server**, **content-length** - **error** message when a URL fails (DNS, timeout, SSL…) ### Input | Field | Type | Description | |---|---|---| | `urls` | array | List of URLs to check (missing scheme defaults to `https://`) | | `url` | string | Convenience field for a single URL (merged with `urls`) | | `method` | enum | `GET` (most accurate) or `HEAD` (lighter; auto-falls back to GET if rejected) | | `followRedirects` | boolean | Follow 3xx and report the chain (default true) | | `timeoutSecs` | integer | Per-URL timeout, 1–60 (default 15) | | `concurrency` | integer | Parallel checks, 1–50 (default 25) | #### Example input ```json { "urls": [ "https://google.com", "http://github.com", "https://apify.com/old-page" ] } ```` ### Output One record per URL: ```json { "input_url": "http://github.com", "final_url": "https://github.com/", "final_status": 200, "ok": true, "redirected": true, "redirect_count": 1, "redirect_chain": [ { "url": "http://github.com", "status": 301, "location": "https://github.com/" }, { "url": "https://github.com/", "status": 200, "location": null } ], "content_type": "text/html; charset=utf-8", "server": "GitHub.com", "response_time_ms": 142, "error": null } ``` ### Use cases - **SEO migrations** — verify every old URL 301-redirects to the right new URL (no chains, no 404s). - **Link audits** — find broken links and unexpected redirects across a sitemap or backlink list. - **Redirect-chain cleanup** — spot multi-hop chains that waste crawl budget and slow users down. - **Uptime spot-checks** — batch-confirm a set of endpoints returns `200`. ### Pricing Pay-per-event, no subscription: **$0.001 per URL checked** ($1 per 1,000 URLs). Up to 1,000 URLs per run — split larger lists across runs. ### Next step: is your site ready for AI crawlers? Status codes are table stakes. To see whether ChatGPT, Claude and Perplexity can actually read and cite your pages, run **[GEO Site Audit](https://apify.com/dltik/geo-site-audit)** — it scores robots.txt, `llms.txt`, sitemap, Schema.org, meta tags and content extractability for AI readiness. *** Built by [dltik](https://apify.com/dltik). Pure HTTP, headers-only — fast and cheap. # Actor input Schema ## `urls` (type: `array`): List of URLs to check (e.g. \["https://google.com", "github.com"]). Missing scheme defaults to https://. ## `url` (type: `string`): Convenience field to check just one URL. Merged with the 'urls' list if both are set. ## `method` (type: `string`): Request method. GET is most accurate; HEAD is lighter but some servers reject it (the actor auto-falls back to GET when that happens). ## `followRedirects` (type: `boolean`): Follow 3xx redirects and report the full chain. Disable to see only the first response. ## `timeoutSecs` (type: `integer`): Per-URL request timeout in seconds (1-60). ## `concurrency` (type: `integer`): How many URLs to check in parallel (1-50). Higher is faster but heavier on the targets. ## Actor input object example ```json { "urls": [ "https://google.com", "http://github.com", "https://apify.com" ], "method": "GET", "followRedirects": true, "timeoutSecs": 15, "concurrency": 25 } ``` # Actor output Schema ## `results` (type: `string`): HTTP status and redirect chain for each URL. # 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 '' with your token const client = new ApifyClient({ token: '', }); // Prepare Actor input const input = { "urls": [ "https://google.com", "http://github.com", "https://apify.com" ] }; // Run the Actor and wait for it to finish const run = await client.actor("dltik/http-status-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); }); // 📚 Want to learn more 📖?
