Sky Mavis

Sky Mavis is the studio behind Axie Infinity and Ronin, an EVM blockchain crafted for developers building games with player-owned economies. Its developer platform exposes a set of API-gateway products for building on Ronin: the Skynet Web3 API (query accounts, NFTs, tokens, blocks, contracts and transactions), a Ronin JSON-RPC API for node connectivity, the Axie Infinity Origins and AXP game-data APIs, Ronin Market and Ronin Store partner APIs, and Ronin Waypoint, an OAuth2/OIDC account service and keyless wallet for game onboarding. Access to gateway products is authenticated with an X-API-KEY issued from the Ronin Developer Console, while public JSON-RPC and the Waypoint OIDC surface are openly reachable. Official SDKs ship for JavaScript/TypeScript, Unity, Android and iOS.

Sky Mavis publishes 3 APIs on the APIs.io network. Tagged areas include Company, Blockchain, Web3, Gaming, and NFT.

Sky Mavis’ developer surface includes documentation, API reference, getting-started guide, engineering blog, signup flow, authentication, sandbox, and 18 more developer resources.
