概览

AI 生成的概览

远程 MCP 服务器，在 Base 上提供确定性的加密、外汇与贸易单据校验，结果附带签名回执，并支持 x402 支付发现。

可以做什么
Code402 提供 24 个工具：Base 链查询（区块信息、ETH 与 ERC-20 余额、nonce 活动、代币合约事实）、带缓存的加密现货价格、静态外汇汇率表，以及 IBAN、LEI、SWIFT/BIC、比利时 VAT、印度 GSTIN、PAN、UPI VPA 和 IFSC 的结构校验。还包括批量校验、供应商入驻包、放款前防护、EVM 地址制裁筛查、Markdown 网页抓取、JSON Schema 校验和文本摘要。多数结果附带签名回执，receipt_verify 可校验任意 x402 服务的回执。
适用场景
当助手需要对加密地址、代币合约或贸易标识做低成本、可重复的检查，或需要确认工具结果已被签名时使用。适合仅需结构校验、无需注册表或身份查询的采购与支付流程。
运行要求
远程 streamable HTTP 端点；未声明任何软件包、账户、API 密钥或环境变量。需要能访问该端点的网络。部分工具需要先前的回执哈希，check_price 会为付费工具返回报价与结算地址。
安装前请注意
多个工具通过 x402 结算收费，依据报价操作可能产生支出；check_price 本身免费。各校验器仅做结构检查，明确不证明所有权、注册状态、银行存在或不存在欺诈，制裁筛查返回 null 状态且不筛查名称。抓取工具会访问任意公开网址，外汇表为静态而非实时。

安装

  1. 打开 控制台中的 Code402，将其添加到工作区。
  2. 为需要使用其工具的对话启用该服务。

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

receipt_verify

Verify any XDR-1 receipt — free, stateless, any issuer

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. Free forever — no account, no quota, no storage (stateless). A valid receipt proves the signer signed that tool call at that timestamp; it does NOT prove funds moved or any business claim.
