Deal Finder — Private Sellers Only (Marketplace + Groups)
Pricing
Pay per usage
Scrapes Facebook Marketplace and Facebook Groups, then filters to genuine private-seller deals: dealers removed, real asking price parsed, accessories dropped, region matched.
What you are hunting for, e.g. "mattress", "iPhone 13", "床墊", "冰箱".
Facebook city slugs, e.g. taipei, taoyuan, hsinchu, losangeles. Leave empty to skip Marketplace.
Public group URLs. Private groups need cookies from an account that is a member.
Substring match against the listing text, e.g. 台北, 新北, 桃園, 新竹. Empty = anywhere.
Drop listings that read like a shop: brand new, in stock, wholesale, warranty, model numbers, free shipping…
Drop cases, covers, spare parts, cleaning services and "wanted to buy" posts.
Only keep listings where an explicit asking price was found. "Original price 6,500" never counts as an asking price.
Your own dealer signals, added to the built-in list.
How many listings to read from each source before stopping. Higher = slower but more coverage.
Useful for tuning: returns everything with filteredReasons explaining each drop.
Playwright-format cookies. Required for private groups. Public Marketplace works without them.
Language of the pages being scraped, e.g. zh-TW, en-US. Affects how prices and dates are read.
