OLX

OLX is an online classifieds marketplace used to buy and sell used goods, vehicles, and property listings between individuals, operating through country-specific sites including its Brazilian edition at olx.com.br, presented in Portuguese.

Listings are posted directly by individuals and cover categories such as vehicles, electronics, and property, and a buyer typically contacts a seller directly to arrange a purchase or viewing.

Its ads.txt file lists 122 authorized ad systems, with 37 direct and 115 reseller entries, and sales houses named include Seedtag Advertising, Adyoulike, and Rich Audience Technologies, reflecting advertising sold largely through third-party partners.
