• 智慧合約的部署與互動
• 區塊鏈資料查詢與分析
• 開發與測試環境

WebSocket (WSS) 端點

Quicknode WebSocket 端點透過針對不同使用情境與效能需求所優化的持久連線，提供即時區塊鏈資料串流服務。

wss://your-endpoint.quiknode.pro/auth-token/

• 智慧合約事件監聽

WebSocket (WSS) 限制

WebSocket 回應設有特定上限，且該上限可能有所變動。若回應可能較大，建議使用 POST 請求。若回應大小超過上限，將顯示對應的錯誤代碼 -32616。

信用使用狀況

Different methods consume different amounts of credits: View Optimism API credit costs →

Flat Rate RPS

Flat Rate RPS is a billing option that provides predictable monthly costs for Optimism 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.
