Deal Finder — Private Sellers Only

Every other Facebook scraper hands you every post in the group. You still have to read 200 dealer ads to find the three real people selling.

This one does the reading.

It scrapes Facebook Marketplace and Facebook Groups, then applies a judgment layer before anything reaches your dataset:

Filter	What it does
Dealer detection	Drops shops and resellers. Trained on the language they actually use — brand new, in stock, wholesale, warranty, model no., free shipping, 全新, 原廠, 現貨, 保固, 免運.
Real price parsing	Pulls the actual asking price out of free text. A listing that says "原價 6,500，便宜售" returns no price, not 500. Discounted cards return the current price, not the strikethrough one.
Accessory removal	Searching mattress stops returning mattress cleaners and fitted sheets. Searching iPhone stops returning cases.
Region matching	Keep only what you can actually drive to.

You are charged only for listings that pass every filter. Everything it throws away is free.

Use cases

• Resellers — find under-priced private listings before the flippers do
• Furniture / appliance flipping — free giveaways and sub-$50 items, dealers removed
• Second-hand phones & laptops — private sellers only, accessories stripped out
• Local buying agents — one run covers several cities and groups

Input

{
  "keyword": "mattress",
  "marketplaceLocations": ["taipei", "taoyuan", "hsinchu"],
  "groupUrls": ["https://www.facebook.com/groups/1274386926940537"],
  "maxPrice": 3000,
  "regions": ["台北", "新北", "桃園"],
  "excludeDealers": true,
  "excludeAccessories": true
}

Give it Marketplace city slugs, group URLs, or both. Public Marketplace works without cookies; private groups need cookies from an account that is a member.

Output

{
  "source": "facebook_marketplace",
  "title": "二手單人床墊 九成新 自取",
  "price": 800,
  "isFree": false,
  "isDealer": false,
  "region": "桃園",
  "authorName": "",
  "url": "https://www.facebook.com/marketplace/item/...",
  "images": ["https://scontent..."],
  "passed": true,
  "filteredReasons": []
}

Set includeFilteredOut: true while you tune — every dropped item comes back with filteredReasons telling you exactly which rule removed it.

Notes

• i_user cookies are stripped automatically. Browsing as a Facebook Page gets you blocked from Marketplace (Pages can't use Marketplace) — a failure mode that silently returns zero results.
• Group feeds are virtualised, so posts are collected while scrolling, not after. "See more" is expanded before reading, so post text is never truncated.
• Group post text contains invisible U+034F characters; they are cleaned before parsing.

Pricing

Event	Price
Actor start	$0.005
Qualified deal	$0.002

A run over 3 cities and 2 groups that surfaces 15 real deals costs about $0.035.
