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 ## Sitemap Walker Pro (Recursive URL Discovery + Filters) Walk sitemaps and sitemap-index trees recursively. Falls back to robots.txt when only a site root is given. Filters URLs by glob, regex, last-modified date, and priority. Emits per-URL rows tagged with optional chunk indexes for parallel downstream actors. --- ### Sitemap Walker Pro Features - Recursive sitemap-index walk — handles real-world sites that fan out across nested indexes (most large sites do), with cycle detection up to 10 levels deep. - robots.txt fallback discovers the sitemap location when you pass a bare site root. - Auto-tries `/sitemap.xml`, `/sitemap_index.xml`, `/sitemap-index.xml`, and `/sitemaps.xml` when no sitemap is given. - Glob and regex include / exclude patterns. Wrap a pattern in `/.../` to treat it as regex; everything else is picomatch glob. - `lastmodSince` and `priorityMin` filters for incremental crawls and SEO triage. - Optional `chunkSize` tags each row with a 0-based chunk index so you can fan out to parallel downstream actors without re-implementing pagination. - Captures hreflang alternates, image / video / news sitemap metadata when publishers ship them. - Pure HTTP, no browser, no proxies. Polite 250 ms courtesy delay per host with automatic 429 / 5xx retry. --- ### Who Uses Sitemap Walker Data? - **SEO teams** — discover the canonical URL set for a site before crawling, deduping, or running rich-result audits. - **Content engineering** — feed downstream Lighthouse, screenshot, or structured-data validator runs with the canonical URL list. - **Migration QA** — diff the URL set before and after a CMS migration, with `lastmodSince` for incremental snapshots. - **AI training-set curators** — pull the publisher-blessed URL list straight from the sitemap, instead of crawling and guessing. - **Competitive research** — see exactly which content competitors mark up for indexing, and how often each section updates. --- ### How Sitemap Walker Pro Works 1. Pass in a list of seed URLs. Each seed can be a sitemap directly, a sitemap-index, or a bare site root. 2. For each seed the actor either fetches the sitemap directly, tries the standard `/sitemap.xml` paths, or (when `fallbackToRobotsTxt` is on) parses `/robots.txt` for `Sitemap:` directives. 3. The walker descends into `` entries recursively up to 10 levels deep, dropping cycles via a shared seen-set across all seeds. 4. URLs are filtered in order: includePatterns → excludePatterns → lastmodSince → priorityMin. Chunk indexes are applied last when `chunkSize` is set. --- ### Input ```json { "seeds": ["https://www.apify.com/sitemap.xml"], "fallbackToRobotsTxt": true, "recurseSitemapIndex": true, "includePatterns": ["**/blog/**"], "excludePatterns": ["/draft/"], "lastmodSince": "2026-01-01", "priorityMin": 0.5, "chunkSize": 100, "maxUrls": 0, "maxItems": 15 } ```` | Field | Type | Default | Description | |-------|------|---------|-------------| | `seeds` | array | required | Sitemap URLs OR site roots. Site roots fall back to robots.txt when `fallbackToRobotsTxt` is on. | | `fallbackToRobotsTxt` | boolean | true | When a seed lacks an explicit sitemap, parse `/robots.txt` for `Sitemap:` directives. | | `recurseSitemapIndex` | boolean | true | Walk into nested `` entries (most large sites use these). | | `includePatterns` | array | — | Glob (`**/blog/**`) or `/regex/`. Empty = include all. | | `excludePatterns` | array | — | Same syntax, applied after include. Exclude wins. | | `lastmodSince` | string | — | ISO date. Only emit URLs with `lastmod >= this`. | | `priorityMin` | number | — | Only emit URLs with `priority >= this` (0.0-1.0). | | `chunkSize` | integer | — | Group output into chunks of this size; tag each row with a chunk index. | | `maxUrls` | integer | 0 | Hard cap on emitted URLs. `0` = unlimited. | | `maxItems` | integer | 15 | Apify-tester safety cap. Override (or set to 0) for production batches. | The effective cap is the smaller of `maxUrls` and `maxItems` when both are set. *** ### Sitemap Walker Pro Output Fields ```json { "url": "https://example.com/blog/post-1", "lastmod": "2026-04-15T10:00:00Z", "changefreq": "weekly", "priority": 0.8, "sourceSitemap": "https://example.com/sitemap.xml", "chunk": 0, "alternates": ["es=https://example.com/es/blog/post-1"], "imageRefs": ["https://example.com/img.jpg;Hero shot"], "videoRefs": [], "newsTitle": null, "newsPublication": null, "newsPublicationDate": null, "newsLanguage": null, "scrapedAt": "2026-04-30T18:00:00Z" } ``` | Field | Type | Description | |-------|------|-------------| | `url` | string | Discovered URL. | | `lastmod` | string | Last-modified timestamp from the sitemap (ISO string). | | `changefreq` | string | `always`, `hourly`, `daily`, `weekly`, `monthly`, `yearly`, or `never`. | | `priority` | number | Priority hint from the sitemap (0.0-1.0). | | `sourceSitemap` | string | URL of the sitemap that contained this entry. | | `chunk` | number | 0-based chunk index when `chunkSize` is set; `0` otherwise. | | `alternates` | array | Pipe-joined `hreflang=href` entries from `xhtml:link rel=alternate`. | | `imageRefs` | array | Pipe-joined `loc;title` entries from image sitemaps. | | `videoRefs` | array | Pipe-joined `title;content_loc` entries from video sitemaps. | | `newsTitle` | string | Google News sitemap title (when present). | | `newsPublication` | string | Google News publication name (when present). | | `newsPublicationDate` | string | Google News publication date (when present). | | `newsLanguage` | string | Google News language code (when present). | | `scrapedAt` | string | Timestamp when this URL was discovered. | *** ### Pricing Token charge — functionally free. Apify rejects truly $0 PPE events, so the per-URL price is the smallest practical floor. | Event | Price | |-------|-------| | Actor start | $0.10 | | Per discovered URL | $0.0001 | | Volume | Cost | |--------|------| | 100 URLs | $0.11 | | 1,000 URLs | $0.20 | | 10,000 URLs | $1.10 | This actor is the cheap discovery primitive that pairs with paid downstream actors. Walk sitemaps liberally. *** ### Limits - `maxItems` defaults to 15 — sized for the Apify tester's 5-minute timeout. Override for production batches by setting `maxItems` higher and / or relying on `maxUrls`. - The actor does not fetch the URLs it discovers. Pair with a downstream actor (HTML scraper, Lighthouse, screenshot, structured-data validator) for that. - Sitemap-index recursion caps at 10 levels deep. Cycles are detected via a shared seen-set across all seeds. - `robots.txt` `Disallow:` rules are not enforced. Sitemaps are explicitly the publisher's invitation to fetch the listed URLs. - `Crawl-delay:` directives are not parsed. The walker uses a fixed 250 ms courtesy delay between requests, plus automatic 429 / 5xx retry handling. - Some publishers compress sitemaps as `.xml.gz` — these are auto-decompressed. *** ### Related Actors - **Structured Data Validator Pro** — feed the discovered URL list straight into structured-data audits. - **SSL & Security Headers Checker** — discover URLs for a site, then probe each one's TLS and header posture. - **Angular SSR State Extractor** — discover an Angular site's URLs, then pull each page's TransferState payload. *** ### Need More Features? Need a different output shape, a warehouse integration, or a pre-wired sitemap → fetch → validate chain? [File an issue](https://console.apify.com/actors/issues) or get in touch. ### Why Use Sitemap Walker Pro? - **Functionally free** — $0.0001 per URL. Walk a million-URL sitemap for $100 and stop arguing about cost. - **Recursive index walk + robots.txt fallback** — handles the messy real world. Most other walkers handle one sitemap and call it a day. - **Chunked output** — tag each row with a 0-based chunk index and fan out to N parallel downstream actors without writing a coordinator. *** Built by [OrbTop](https://orbtop.com). # Actor input Schema ## `sp_intended_usage` (type: `string`): Please describe how you plan to use the data extracted by this crawler. ## `sp_improvement_suggestions` (type: `string`): Provide any feedback or suggestions for improvements. ## `sp_contact` (type: `string`): Provide your email address so we can get in touch with you. ## `seeds` (type: `array`): List of sitemap URLs OR site root URLs.
