# Gameflip > Gameflip is a digital marketplace for buying and selling games, in-game items, gift cards, game accounts, and gaming services, with escrow-style buyer protection and a built-in wallet. The Gameflip API (GFAPI) is a JSON REST API (base path /api/v1) for managing listings, searching the marketplace, running exchanges, reading account/wallet data, and handling Steam item escrow and bulk trade-offer listings. Auth is an API key plus a rotating TOTP one-time password sent in the Authorization header (`GFAPI :`); access is Beta and gated through Gameflip account settings. ## APIs - [Gameflip API (GFAPI)](https://gameflip.github.io/gfapi/): REST API for listings, exchanges, account/wallet, and Steam escrow/bulk.
