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.
Limited machine-readable signal and partial portal coverage — documentation a human can read, but little a machine or agent can consume without scraping.
API Evangelist profiles Sky Mavis the way a machine reads it — 7 machine-readable artifacts across 3 APIs, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Sky Mavis scores 41.0/100 (thin), with a separate agent-readiness read of 38/100 (agent aware). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

How we profile Sky Mavis
Each block below is one kind of artifact we hold for Sky Mavis. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
APIs 3
Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.
Individual APIs this provider publishes, each with its own machine-readable definition.
Ronin Skynet Web3 API
REST Web3 data API on the Ronin blockchain — query accounts, NFTs, tokens, collections, blocks, smart contracts and transactions. Authenticated with an X-API-KEY issued from the...
Ronin JSON-RPC API
Ethereum-compatible JSON-RPC endpoint for the Ronin network — read chain state, submit transactions, call contracts, and subscribe to events. The public mainnet endpoint is open...
Ronin Waypoint Account Service
OAuth2 / OpenID Connect account service and keyless wallet for onboarding players into Ronin games. Discovery is published at the athena.skymavis.com issuer; supports authorizat...
MCP Servers 1
Model Context Protocol servers expose these APIs directly to AI agents. We profile them because agent-native access is the fastest-growing way this provider's capabilities actually get used.

MCP SERVERSecurity Posture 2
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.

Scopes 1
OAuth scopes are the vocabulary of least-privilege access. Profiling them shows exactly what an integration — or an agent acting on a user's behalf — is allowed to do.
