Sui

Sui is a next-generation Move-based blockchain developed by Mysten Labs, designed for high throughput, low latency, and an asset-oriented programming model. It provides gRPC, GraphQL, and legacy JSON-RPC interfaces for querying objects, transactions, checkpoints, events, and balances on the Sui network. The gRPC API is the current recommended interface, replacing the deprecated JSON-RPC, while GraphQL RPC offers flexible reads for frontends and dashboards.

Sui publishes 9 APIs on the APIs.io network, including Coin Query API API, Extended API API, Governance Read API API, and 6 more. Tagged areas include Blockchain, Move, Web3, Cryptocurrency, and Smart Contracts.

The Sui catalog on APIs.io includes 1 Spectral governance ruleset.

Sui’s developer surface includes documentation, GitHub presence, engineering blog, changelog, and 13 more developer resources.
