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 ## County Tax Sale Auction Monitor — Nationwide Calendar **Every county tax sale auction in one structured feed — and know the moment a new one is announced.** County tax-defaulted and tax-foreclosed property auctions are where real estate investors find deeply discounted deals — but the schedules live scattered across county sites and auction platforms, and the investors who hear about a sale first get the research head start. This actor turns the nationwide auction calendar into clean structured data: county, state, sale type, dates, status, and a direct auction link per record — currently covering the Bid4Assets platform (county sales across CA, WA, PA, NV, MN and more). ### What it does - 📅 Aggregates scheduled and announced county auctions into one dataset - 🏷️ Classifies sale types: tax-defaulted, tax-foreclosed, judicial, repository, tax-title, surplus, sheriff - 🔎 Filters by state, county, sale type, and upcoming-only - 🚨 **New-auction detection**: flags every auction announced since your previous run — schedule daily and get an early-alert feed via Apify's Slack/email/webhook integrations - 🤖 API, schedules, and **MCP** ready — AI agents can ask "what tax sales are coming up in California?" against live data ### Who uses this - **Real estate investors & wholesalers** tracking tax deed and foreclosure auctions across markets - **Land investors** watching rural county sales that never hit mainstream listing sites - **Fund & research teams** analyzing distressed inventory flow by state and season - **AI agents** doing autonomous deal-flow monitoring ### Output example ```json { "platform": "Bid4Assets", "title": "Riverside County, CA Tax Defaulted Properties Auction", "county": "Riverside", "state": "CA", "saleType": "tax-defaulted", "startDate": "2026-04-23", "endDate": "2026-04-28", "status": "announced", "isNew": true, "auctionUrl": "https://www.bid4assets.com/county-tax-sales", "scrapedAt": "2026-07-14T15:04:05.000Z" } ```` ### Input options | Field | Description | Default | |---|---|---| | `states` | e.g. `["CA","WA","PA"]` | all | | `counties` | e.g. `["Riverside","Pierce"]` | all | | `saleTypes` | tax-defaulted, judicial, sheriff... | all | | `upcomingOnly` | Skip past auctions | true | | `detectNew` | Flag newly announced auctions | true | | `onlyNew` | Output only new announcements (alert mode) | false | ### The early-alert workflow 1. Schedule daily with `detectNew: true` (add `onlyNew: true` for a pure alert feed) 2. Wire an Apify integration (Slack, email, webhook) to the run 3. You now hear about every newly announced county sale the morning it appears — while other investors are still checking pages by hand ### Roadmap Property-level lists per auction (parcels, minimum bids, assessed values) and additional platforms (Florida tax deed calendars, GovEase) are next — open an issue to vote on what lands first. ### FAQ **Where does the data come from?** Public county auction calendars published on auction platforms, starting with Bid4Assets (100+ counties historically). **How current is it?** Every run fetches the live calendar; nothing cached between runs. **Why is an auction's status "announced" vs "scheduled"?** Scheduled auctions have a live auction page; announced ones have a date but no page yet — those are the earliest signals. *** *Part of a family of normalized market-data actors: GPU Cloud Price Tracker and AI Model API Pricing Monitor.* # Actor input Schema ## `states` (type: `array`): Two-letter state codes to include, e.g. \['CA','WA','PA']. Empty = all states. ## `counties` (type: `array`): County names to include, e.g. \['Riverside','Pierce']. Case-insensitive substring match. Empty = all counties. ## `saleTypes` (type: `array`): Only include these sale types. Empty = all. ## `upcomingOnly` (type: `boolean`): Skip auctions whose end date has already passed. ## `detectNew` (type: `boolean`): Compares against your previous run (stored in a named key-value store) and flags auctions announced since. Schedule daily runs to get an early-alert feed. ## `onlyNew` (type: `boolean`): When detection is on, output only auctions announced since your last run. Perfect for alerting workflows. ## Actor input object example ```json { "states": [], "counties": [], "saleTypes": [], "upcomingOnly": true, "detectNew": true, "onlyNew": false } ``` # 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 = { "states": [] }; // Run the Actor and wait for it to finish const run = await client.actor("genetheaiguy/county-tax-sale-monitor").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 📖?
