Facebook Marketplace Monitor: Listings, Price & Sold Status

⚡ 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/<city>/search/?query=...), Category URL (/marketplace/<city>/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? Use our Facebook Marketplace Seller & Inventory Scraper.)
