They run on the Apify platform to scrape websites, process data, connect APIs, and automate workflows. 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. - **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use). - **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`. - **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`. - **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`. - **Any other language** — the [REST API](https://docs.apify.com/api/v2.md). For usage examples, see the [API](#api) section below.

Built for live auction tracking, dynamic sniping strategies, valuation research, and automated bid monitoring across high-value collectibles, art, luxury watches, and antiques. ### ⚡ Features Live Bid & Token Tracking: Monitor the highest bidder's token (highest\_bidder\_token), winning bidder token (winner\_token), and total bid counts in real time. Multi-Currency Pricing: Extract current bid amounts pre-converted into EUR, USD, GBP, and local currency values. Auction Timers & Status: Access exact start times (bidding\_start\_time), countdown end times (bidding\_end\_time), and auction closure state (closed). Reserve & Buy-Now Indicators: Track whether the seller's secret reserve price has been met (reserve\_price\_met) and detect instant is\_buy\_now\_available opportunities. Real-Time Channel Identification: Collect active WebSocket channels (realtime\_channel) for direct live event integration. ### 🔍 Use Cases Live Auction Sniping & Automated Bidding: Feed real-time bid changes and countdown timers into trading algorithms to place last-second bids. Price & Reserve Analytics: Monitor reserve price thresholds and bidding momentum across targeted categories like fine wine, classic cars, or jewelry. Auction Portfolio Management: Keep track of favorite count trends (favorite\_count) and bid escalations on active listings simultaneously. Market Research & Valuation: Collect bid progression histories to evaluate real-world buyer interest for rare collectibles. ### 📦 Output example ```json { "highest_bidder_token": "c33ff1ea0880706bb13d329a74cbf1490fc32be2", "winner_token": null, "current_bid_amount": { "EUR": 300.0, "USD": 347.0, "GBP": 257.0 }, "bidding_start_time": "2026-08-07T10:00:00Z", "bidding_end_time": "2026-08-15T19:25:55Z", "reserve_price_met": true, "favorite_count": 31, "closed": false, "id": 105540145, "auction_id": 1247249, "is_buy_now_available": false, "realtime_channel": "CWAUCTION-production-1247249", "use_realtime_message_fallback": false } ``` ### 🛟 SUPPORT Share your runs with the developer team and create issues on error to help us improve actor quality.
