**APIs profiled:** 11

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.
