Overview

Sui gRPC API provides high-performance access to network data through gRPC interfaces. It serves as a powerful tool for developers who need to:

• Access blockchain data with low latency
• Monitor on-chain activities and state changes
• Query account and object states efficiently
• Execute transactions with minimal overhead

Access

You can access Sui gRPC directly through your existing QuickNode Sui endpoint—no additional add-ons are needed. The gRPC services are available on port 9000, a dedicated and secure channel for gRPC communication.

Endpoint and Token Configuration

When connecting to Sui gRPC services, the port must be specified in the URL:

• Endpoint: The name of your endpoint followed by .sui-mainnet.quiknode.pro and the port number 9000 (e.g., https://docs-demo.sui-mainnet.quiknode.pro:9000)
• Token: The alphanumeric string that follows the endpoint name in the URL

For example, if your endpoint looks like this: https://docs-demo.sui-mainnet.quiknode.pro/123456789/, then your authentication credentials would be:

• Endpoint: https://docs-demo.sui-mainnet.quiknode.pro:9000
• Token: 123456789
