  • 在 Base、以太坊與 XRPL 上執行 JSON-RPC 呼叫,包含以固定費率查詢 eth_getLogs
  • 領取含免費額度的 API 金鑰,並比較信用卡手續費與 UnFee 定價
  • 產生零手續費的加密支付連結、結帳頁、QR 碼與嵌入語法
  • 驗證交易雜湊,查詢賣家或 x402 服務商的交付信譽
  • 僅在 HTTP 200 交付證明下結算 x402 付款,並追蹤錢包的刷量交易
  • 產生 IRS 8949 表格與成本基準稅務報告並匯出 CSV,偵測地址前後綴仿冒
適用情境
適合需要跨 Base、以太坊與 XRPL 讀取鏈上資料且不想按運算單位計費的情境,也適用於加密收款、x402 支付驗證、錢包稅務申報與地址投毒防護。
執行需求
遠端 streamable HTTP 端點 unfee.xyz;清單未宣告驗證或請求標頭。API 金鑰需透過 get_instant_free_rpc_key 工具領取,部分工具說明以 x402 單次付費或按月訂閱。
