AI Arena

AI Arena is a web3/AI gaming company built by ArenaX Labs, backed by Paradigm and Framework Ventures. Its flagship title, AI Arena, is an Ethereum/Arbitrum-native PvP fighting game where players purchase, train through imitation learning, and battle characters powered by real artificial intelligence, with a native $NRN (Neuron) token and an on-chain marketplace for AI models. Beyond the game, ArenaX Labs ships developer infrastructure for reinforcement learning: RLMesh, an open-source, Gymnasium-compatible framework that connects RL models to environments across process, dependency, and machine boundaries over a gRPC wire protocol (rlmesh-wire-v1), with Python and Rust SDKs; and SAI (competesai.com), a gamified RL research and competition platform with its own CLI. This profile was enriched by the API Evangelist pipeline from public sources — GitHub, package registries, and the RLMesh documentation.

AI Arena is profiled on the APIs.io network. Tagged areas include Company, Gaming, Web3, Artificial Intelligence, and Reinforcement Learning.

AI Arena’s developer surface includes documentation, API reference, getting-started guide, engineering blog, CLI, changelog, authentication, and 15 more developer resources.
