# Public Feed Discovery & Latest Items Agent (`jacksu/public-feed-discovery-agent`) Actor Discover public RSS, Atom, and JSON Feed endpoints, then return latest items, freshness, focus-term matches, diagnostics, and useful-result pricing. - **URL**: https://apify.com/jacksu/public-feed-discovery-agent.md - **Developed by:** [jack su](https://apify.com/jacksu) (community) - **Categories:** Automation, SEO tools, AI - **Stats:** 2 total users, 1 monthly users, 100.0% runs succeeded, NaN bookmarks - **User rating**: No ratings yet ## Pricing from $5.00 / 1,000 useful feed discovery results 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 ## Public Feed Discovery & Latest Items Agent Find public RSS, Atom, and JSON Feed endpoints for a site or direct feed URL, then return a bounded latest-items brief with source feed URLs, publication dates, freshness metrics, focus-term matches, evidence URLs, confidence, and diagnostics. This Actor is for content operations, SEO, market monitoring, PR, newsletter research, and AI ingestion planning when you need to know whether a public site has usable feed data before building a larger crawl or article pipeline. ### What It Returns - Sanitized input URL and site origin - Same-site feed URLs found from public HTML or common feed paths - Candidate feed evidence showing direct input, HTML discovery, or common-path probing plus readable/fetch/parse status - RSS, Atom, or JSON Feed summaries - Latest feed items with title, sanitized item URL, published date, author, summary snippet, source feed URL, and matched focus terms - Freshness summary with date coverage and recent item counts - Feed discovery hash - Evidence URLs - Confidence, completeness, missing fields, diagnostics, and readable errors ### Pricing Design The intended pay-per-event setup is: - `apify-actor-start`: a tiny run-start fee - `useful-feed-discovery-result`: charged only for useful public feed discovery records with at least one readable feed and one item - no `apify-default-dataset-item` If `focusTerms` are supplied, the useful event is charged only when at least one feed item matches a focus term. Invalid inputs, duplicates, private-network URLs, empty feeds, failed resources, and focus-term misses should not charge the useful event. ### Good Fits - Discovering whether a public website exposes RSS, Atom, or JSON Feed data - Building a source list for content monitoring - Finding recent public posts around a focus topic - Preparing feed-backed inputs for AI/RAG workflows - Auditing feed freshness and date coverage ### Boundaries This Actor does not crawl full articles, log in, use cookies, render JavaScript, scrape search engines, scrape social platforms, bypass paywalls, or read private feeds. It fetches only public same-site HTML and feed resources. Credentials, query parameters, fragments, path params, private-network addresses, localhost, `.local`, sensitive reset/invite paths, and token-like paths are rejected, skipped, or safely redacted. Item URLs are sanitized and are not fetched. # Actor input Schema ## `sitesOrFeedUrls` (type: `array`): Public site origins, site pages, domains, or direct RSS/Atom/JSON Feed URLs. Query parameters, fragments, credentials, path params, and private-network addresses are rejected. ## `focusTerms` (type: `array`): Optional terms to match in feed item titles and summaries. When supplied, useful-result charging requires at least one match. ## `maxFeedsPerSite` (type: `integer`): Maximum number of same-site feed files to parse per input. ## `maxItemsPerFeed` (type: `integer`): Maximum latest items to keep from each parsed feed. ## `requestTimeoutSecs` (type: `integer`): Maximum time in seconds to wait for each public HTML or feed request. ## Actor input object example ```json { "sitesOrFeedUrls": [ "https://blog.apify.com" ], "focusTerms": [ "automation", "web scraping" ], "maxFeedsPerSite": 3, "maxItemsPerFeed": 10, "requestTimeoutSecs": 20 } ```` # Actor output Schema ## `datasetId` (type: `string`): No description # API You can run this Actor programmatically using our API.
