概覽

AI 產生的概覽

遠端 x402 檢查器：免費探測 402 付款端點，並按次販售小額查詢，涵蓋加密與網頁資料、時間與行事曆工具。

可以做什麼
探測 x402 付款端點，回傳 payTo、金額、網路與資產；可批次檢查最多十個網址，或對單一端點產生結構化誠信報告（免費 check，付費 batch 與 report）。查詢加密與鏈上資料：位址餘額、交易、區塊、Gas、代幣中繼資料、函式選擇器、ENS 名稱、價格、DEX 交易對、代幣安全、Polymarket 賠率與恐懼貪婪指數。檢查網頁與網域資訊：將頁面轉為 markdown、匯出回應標頭、追蹤重新導向、依 JSON Schema 驗證資料，以及 DNS、TLS 與郵件 MX 檔案。檢索公開來源：Hacker News、arXiv、Stack Overflow、CVE、GitHub、維基百科與加密新聞。取得實用資訊：地理編碼、天氣、法幣匯率、股票與指數報價、時區、cron 解析、美國工作日曆與目前時間。
適用情境
適合在助理需要先核實某個 x402 付費端點再決定是否付款時使用，也適合希望用一個託管端點完成多種小型查詢（鏈上資料、網域與 TLS 資訊、公開檢索、時間與行事曆工具）而不必自行串接多個 API 的情境。
執行需求
遠端 Streamable HTTP 端點；未宣告驗證、環境變數或請求標頭。除免費的 check 與 board 外，多數工具按次以 Base 上的 USDC 付款至所列 payTo 位址，因此需要已儲值的錢包與支援 x402 的用戶端。另有可選的本機 stdio 模式，但只提供免費的 check。
安裝前請注意
幾乎所有工具都按次收費（約 0.01 USDC，report 與 bid 為 0.05，新聞為 0.001），且查詢無結果或未知時仍會扣費。付費工具會把所查詢的網址、位址或主機名傳送給營運方及第三方公開 API。README 稱其不花錢、不自付，但付費項目仍需呼叫方錢包付款。
