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.

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/.
