Zed.run

Zed.run is a digital horse racing platform where players buy, breed, and race NFT racehorses, originally built on the Ethereum and Polygon blockchains and developed by Virtually Human Studio. Players collect uniquely bred digital racehorses as non-fungible tokens, enter them into skill- and bloodline-based races, and trade them on a secondary marketplace. Zed.run was surfaced as a portfolio company of a16z and added to the API Evangelist network for enrichment. As of this enrichment pass the public API host (api.zed.run) returns a "zed shutdown" message, indicating the developer/API surface is currently discontinued or paused, so no live API artifacts could be harvested.

Zed.run is profiled on the APIs.io network. Tagged areas include Company, Gaming, Blockchain, NFT, and Web3.
