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/docs.md): ```bash npm install apify-client ``` In Python projects, use official [Python client library](https://docs.apify.com/api/client/python/docs.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/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 ## newsletter-rss-author-contact-extractor Production-ready Apify Actor for extracting public-source newsletter/blog/feed summaries, post authors, contact clues, and lightweight content signals. ### Features - Node 20+ ESM actor - Accepts `feedUrls`, `startUrls`, `domains`, `maxPosts`, and `includeContactDiscovery` - Parses public RSS/Atom feeds and public HTML pages - Best-effort recognition for Substack, Beehiiv, and Ghost-style pages - Emits one `source_summary` row per source and one `post_author` row per extracted post - Extracts author name, title, date, topics, sponsor/ad clues, outbound domains, emails, socials, contact URLs, evidence URLs, and confidence - Deterministic smoke tests using local fixtures only ### Input See `.actor/input_schema.json` and `examples/sample-input.json`. ### Output shape Each dataset row contains: - `rowType` - `sourceType` - `sourceUrl` - `siteUrl` - `domain` - `sourceTitle` - `authorName` - `postTitle` - `publishedAt` - `topics` - `sponsorAdClues` - `outboundDomains` - `emails` - `socials` - `contactUrls` - `evidenceUrls` - `confidence` ### Local usage ```bash npm install npm test npm run smoke ```` `npm run smoke` reads `examples/sample-input.json`, rewrites local fixture URLs, and writes stable output to `test-output/smoke-output.json`. ### Constraints - Public sources only - No login, private API, or bypass behavior - Feed and HTML parsing are intentionally narrow and deterministic # Actor input Schema ## `feedUrls` (type: `array`): Public RSS or Atom feed URLs to parse. ## `startUrls` (type: `array`): Public blog, newsletter, or homepage URLs to inspect. ## `domains` (type: `array`): Domains to inspect using their homepage as a public source seed. ## `maxPosts` (type: `integer`): Maximum number of feed or page posts to emit per source. ## `includeContactDiscovery` (type: `boolean`): Extract emails, socials, and contact/about page URLs from public HTML. ## Actor input object example ```json { "feedUrls": [], "startUrls": [], "domains": [], "maxPosts": 10, "includeContactDiscovery": true } ``` # 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 = {}; // Run the Actor and wait for it to finish const run = await client.actor("isotonic/newsletter-rss-author-contact-extractor").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 📖?
