Gameflip

Gameflip is a digital marketplace where gamers buy and sell games, in-game items, gift cards, game accounts, boosting/coaching gigs, and other digital goods, backed by an escrow-style buyer guarantee and a built-in wallet. For developers and power sellers, Gameflip publishes the GFAPI — a JSON REST API (base path /api/v1) for creating and managing listings, searching the marketplace, running exchanges (sell/buy records), reading account profiles and wallet history, and handling Steam item escrow and bulk trade-offer listings. Requests are authenticated with an API key plus a rotating TOTP one-time password sent in the Authorization header (`GFAPI :`). Access is Beta and gated: API keys and TOTP secrets are issued to selected developers through Gameflip support / account settings. An official Node.js client library (gfapi) with sample code is published by Gameflip.

Gameflip publishes 6 APIs on the APIs.io network, including Account API, Exchange API, Listing API, and 3 more. Tagged areas include Company, Gaming, Marketplace, Digital Goods, and E-Commerce.

Gameflip’s developer surface includes getting-started guide, documentation, API reference, support, engineering blog, signup flow, authentication, and 12 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Payments regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.
The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. This rating is computed from github.com/api-evangelist/gameflip: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you? Prioritized profiling — $2,500 →
