概覽

AI 產生的概覽

遠端 MCP 伺服器，在 Base 上提供確定性的加密、外匯與貿易文件檢核，結果附簽章回執，並支援 x402 付款探索。

可以做什麼
Code402 提供 24 個工具：Base 鏈查詢（區塊資訊、ETH 與 ERC-20 餘額、nonce 活動、代幣合約事實）、附快取的加密現貨價格、靜態外匯匯率表，以及 IBAN、LEI、SWIFT/BIC、比利時 VAT、印度 GSTIN、PAN、UPI VPA 與 IFSC 的結構檢核。另有批次檢核、供應商上線包、撥款前防護、EVM 位址制裁篩查、Markdown 網頁擷取、JSON Schema 驗證與文字摘要。多數結果附簽章回執，receipt_verify 可驗證任一 x402 服務的回執。
適用情境
當助理需要對加密位址、代幣合約或貿易識別碼做低成本、可重複的檢查，或需確認工具結果已簽章時使用。適合只需結構檢核、不需註冊表或身分查詢的採購與付款流程。
執行需求
遠端 streamable HTTP 端點；未宣告任何套件、帳號、API 金鑰或環境變數。需要能連線至該端點的網路。部分工具需要先前的回執雜湊，check_price 會為付費工具回傳報價與結算網址。
安裝前請注意
多個工具透過 x402 結算收費，依報價操作可能產生支出；check_price 本身免費。各檢核器僅做結構檢查，明確不證明所有權、註冊狀態、銀行存在或無詐欺，制裁篩查回傳 null 狀態且不篩查名稱。擷取工具會存取任意公開網址，外匯表為靜態而非即時。

Instant zero-cost pricing hook for code402 tools. Returns the live price, an opaque quote_id, TTL, and the settlement URL.

Verifies a signed XDR-1 receipt from ANY x402 service: recomputes the canonical digest and recovers the signer, then compares it to the declared signer.
