Since this Actor supports Apify Store discounts, the price gets lower the higher subscription plan you have.

It has two run modes. 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. Apify vocabulary and the platform model are defined once, in the agent quickstart at https://apify.com/agents.md. ## 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. Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run. For examples already wired to this Actor's own input schema, see the [API](#api) section below. Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`). # README ## ⚡ Facebook Marketplace Monitor — Listings, Price Drops, Sold Status & Deal Alerts

**Monitor Facebook Marketplace listings, search feeds, category URLs, mobile share links (`/share/...`), or Item IDs in real time.**\ Track live availability (`ACTIVE`, `SOLD`, `PENDING`, `REMOVED`), automatically calculate markdown price drops (`strikethrough_price`, `previous_numeric_price`, `price_drop_amount`, `price_drop_percent`, `has_price_drop`), and run scheduled new-deal alerts with 7-day stateful deduplication (`enable_monitoring_cache`). ***

*** ### 🎯 3 Monitoring Modes in One Actor #### 1. Watchlist Status & Price-Drop Monitoring (`start_urls`) Pass specific Facebook Marketplace **Item URLs** (`/marketplace/item/123456789/`), **Mobile Share Links** (`https://www.facebook.com/share/19rRutijnq/`), or **raw numeric Item IDs** (`"1375661437981341"`) to audit inventory health: - **Live Availability Status:** Normalized `listing_status` (`"ACTIVE"`, `"SOLD"`, `"PENDING"`, `"REMOVED"`), `is_sold`, and `is_pending` flags. - **Automatic Markdown & Price-Drop Calculation:** Extracts `price`, `numeric_price`, `strikethrough_price`, `previous_numeric_price`, exact dollar savings (`price_drop_amount`), percentage discount (`price_drop_percent`), and `has_price_drop`. - **Complete Item & Seller Enrichment:** Extracts full descriptions, 5-star seller ratings, vehicle VIN/mileage, and property rental specs (beds, baths, sqft, walk score). #### 2. Scheduled New-Deal & Keyword Monitoring (`search_query` + `enable_monitoring_cache`) Monitor any keyword, category, and city or 5-digit US ZIP code on an **Apify Schedule** (every 15 minutes, hourly, or daily): - **Stateful 7-Day Cross-Run Deduplication (`enable_monitoring_cache: true`):** Remembers previously discovered listing IDs, prices, and statuses in a persistent Apify Key-Value Store (`fb-marketplace-monitor-state`). - **Zero Wasted Spend on Unchanged Listings:** Unchanged items already seen in previous runs are skipped during discovery *before* deep inspection or event billing—so scheduled runs only output **brand-new listings**, **price drops**, or **status changes**. #### 3. Search & Category URL Feed Monitoring (Browser Search & Category Menu Links) Paste any Facebook Marketplace Search URL (`/marketplace//search/?query=...`), Category URL (`/marketplace//vehicles/`), or Category Menu URL (`?category_id=...&query=Vehicles&referral_ui_component=category_menu_item`) into `start_urls` to monitor matching listings and price drops across runs. *(Need to extract a specific seller's complete active + sold catalog from an item URL?
