What is Sui?

Sui is a high-performance layer-1 blockchain focused on low-latency transaction processing and horizontal scalability. Built around the Move programming language, it enables fast finality and high throughput for on-chain applications like gaming, finance, and real-time experiences. Developers write smart contracts in Move, a Rust-based language designed for secure and efficient execution.

Interacting With Sui APIs

Sui provides multiple API interfaces for blockchain interaction:

• GraphQL - Flexible queries with precise field selection and nested data access for efficient retrieval (Beta)
• JSON-RPC - Traditional RPC methods for querying objects, executing transactions, and interacting with Move contracts (Deprecated, deactivating July 2026)
• gRPC - High-performance protocol for efficient queries and transaction submissions. Includes archive support for historical data beyond 14 epochs

You can connect by running your own Sui node with the appropriate interfaces enabled, or by using a hosted provider such as Quicknode, which offers reliable, low-latency access without the need to manage infrastructure.

Make Sui API Calls

The quickest way to start building on Sui is to create a Quicknode endpoint and send your first request. Quicknode provides managed Sui endpoints, offering:

• High reliability — globally distributed infrastructure designed to minimize downtime
• Enhanced performance — optimized latency and request handling for production-grade apps

Visit the QuickStart page to create your endpoint and send your first request.
