- Web3 application backends and APIs
- Smart contract deployment and interaction
- Blockchain data queries and analysis
- Development and testing environments
WebSocket (WSS) Endpoints
Quicknode's WebSocket endpoints provide real-time blockchain data streaming through persistent connections optimized for different use cases and performance requirements.

- DeFi applications requiring real-time price feeds
- Block explorers and analytics dashboards
- Transaction monitoring and confirmation tracking
- Smart contract event listening
WebSocket (WSS) Limits
WebSocket responses are capped at a certain limit, which is subject to change. In cases where responses are potentially large, it is recommended to use a POST request. If the response size exceeds the limit, the associated error code will be -32616.
Credit Usage
Different methods consume different amounts of credits: View Solana API credit costs →
Flat Rate RPS
Flat Rate RPS is a billing option that provides predictable monthly costs for Solana endpoints. Instead of metering individual requests and charging with API Credits, you pay a fixed monthly fee based on your configured request capacity. Your bill stays the same each month regardless of actual usage.
You can check the Flat Rate RPS documentation to learn more.
