What Problems Does This Tool Solve?

When sourcing cars, homes, rentals, or high-value goods on Facebook Marketplace, a single listing page only tells half the story:

1. Disguised Car Dealers ("Curbstoners") Posing as Private Owners: Unlicensed car flippers and commercial auto lots frequently post under personal Facebook accounts (vehicle_seller_type: "PRIVATE_SELLER") so buyers and dealership acquisition teams think they are buying a personal car from its original owner — when the seller actually has dozens of vehicles listed across their profile.
2. Undisclosed Real Estate Brokers & Agents Posing as Direct Homeowners: Buyers and renters searching for direct-from-owner ("For Sale By Owner" / direct landlord) homes, apartments, and land frequently waste time contacting listings that appear to be private owners, only to discover the poster is a leasing agent or property broker managing a large portfolio.
3. Distinguishing Moving Sales from Commercial Dealers: Provides clear inferred_seller_tier (PRIVATE_INDIVIDUAL, MULTI_ITEM_FLIPPER, HIGH_VOLUME_DEALER) and is_undisclosed_dealer (true / false) output fields so direct homeowners or private car sellers having a household moving sale are separated from commercial dealers and brokers.
4. Consolidated Seller Catalog & Sold History: Instead of manually inspecting profiles one by one, you can provide any single listing URL or ID and receive the seller's active catalog (active_listings) and recently sold listings (sold_listings) in one structured output.

Common Use Cases

• Direct-from-Owner Real Estate & Property Sourcing: Distinguish direct homeowners and landlords (PRIVATE_INDIVIDUAL, is_undisclosed_dealer: false) from undisclosed real estate agents, property managers, and land brokers (HIGH_VOLUME_DEALER, is_undisclosed_dealer: true) — or audit a brokerage agent's active and leased properties from a single listing link.
• Automotive Dealership Acquisition & Curbstoner Filtering: Focus your acquisition team on genuine private-party vehicles (PRIVATE_INDIVIDUAL) by filtering out curbstoners and commercial car flippers (is_undisclosed_dealer: true), or track competing dealerships' active lots and recently sold vehicles (sold_listings).
• Competitor Dealer & Reseller Inventory Tracking: Starting from a single listing URL, extract up to 100 active and recently sold listings belonging to that seller, including current prices, strikethrough markdowns (original_price), mileage/subtitles, and availability status.
• Seller Due Diligence, Trust & Fraud Prevention: Check account creation date (join_date_iso), 5-star seller rating (seller_rating, seller_review_count), combined buyer/seller rating (combined_rating), and personal profile URL (personal_vanity_url) before high-value transactions.
• Local E-Commerce & Liquidation Intelligence: Monitor inventory velocity, pricing (numeric_price), and sold turnover for electronics resellers, furniture liquidators, and equipment dealers.

     • PRIVATE_INDIVIDUAL — Direct private car owners, direct homeowners/landlords, or casual individuals
   • is_undisclosed_dealer — Boolean indicator (true / false) for commercial car curbstoners, unbadged real estate brokers, and high-volume resellers operating under personal accounts
   • vehicle_seller_type, dealership_name, is_seller_business_onboarded, & should_show_business_seller_label — Official commercial account flags

3. Active & Recently Sold Inventory Fields

   • active_listings & sold_listings — Arrays of active and recently sold items from the seller's catalog
   • Every listing object includes item_id, url, title, price, numeric_price, original_price, status (ACTIVE, SOLD, PENDING), city, state, image_url, subtitles (e.g., vehicle mileage), seller_id, and is_seed_item
   • Single Charge Per Seller Per Run — If your input list contains multiple item URLs from the same seller, that seller's output record is returned and billed only once.

Data Coverage, Accuracy & Realistic Limitations

We believe in strict transparency so you know exactly what to expect before integrating this tool into your workflow. We do not guarantee 100% extraction of every listing or profile field on Facebook Marketplace.

Data Category / Output Fields	Observed Fill / Accuracy Rate	Important Notes & Realistic Limitations
Seller Identity & Join Date (seller_id, seller_name, join_date_iso, marketplace_profile_url)	~98–100% (on active items)	Returned whenever the input listing is active and publicly accessible on Facebook Marketplace. Deleted, expired, or unavailable listings return an error.
Listing Card Fields (item_id, url, title, price, numeric_price, status, city, image_url)	~98–100%	Populated for each item inside active_listings and sold_listings. Optional fields like original_price (strikethrough price) and subtitles are populated when present on the listing.
Active & Sold Inventory Completeness (active_listings, sold_listings)	~75–95% typical coverage (Not guaranteed 100% exhaustive)	We do not guarantee that 100% of a seller's active or sold listings will be returned. While the output typically includes 75%–95% of a seller's active inventory (up to 100 listings per seller) and recently sold items, some active or historical listings may not be returned depending on platform visibility and listing availability at the time of the run.
Dealer / Broker / Flipper Classification (inferred_seller_tier, is_undisclosed_dealer)	~85–92%	Automated classification fields — not official government or legal licensing records. We do not guarantee 100% classification accuracy in every case.
Seller Star Ratings & Review Counts (seller_rating, seller_review_count, combined_rating)	100% when public (~50–65% of sellers overall)	Populated whenever public star ratings are displayed on the seller's profile. Returns null if the seller has not yet received enough ratings to display a public score or has set ratings to private (seller_ratings_are_private: true).
Personal Profile URL (personal_vanity_url, personal_vanity_handle)	~55–65% of sellers	Populated when a public profile handle is available for the account (null otherwise).

Additional Scope Notes

• Input Format: Provide any Facebook Marketplace Item URL (https://www.facebook.com/marketplace/item/<id>/) or numeric Item ID.
• Up to 100 Listings Per Seller: Returns up to 100 listings (active + recently sold) per seller (max_items_per_seller: 1–100), with your input listing included at index 0 (is_seed_item: true). You are only billed for the exact number of listings returned.
• Rating Aggregates Only: Outputs 5-star rating averages and review counts (seller_rating, combined_rating), not individual written buyer review text comments.
