概覽

AI 產生的概覽

遠端 x402 閘道，讓助理以 USDC 按次付費購買加密行情、DeFi、錢包風險與市場資料服務，並提供一份免費的服務清單。

可以做什麼
  • 列出閘道販售的付費服務及其價格與呼叫路徑
  • 評估代幣與錢包風險：Solana rugcheck 評分、空投與粉塵代幣防禦、錢包持倉估值
  • 分析 DeFi 流動性池，並取得以太坊、Base、Polygon 的即時幣價與 Gas 費用
  • 在 Solana 上搜尋 NFT 系列，在 ERC-8004 註冊表中搜尋鏈上 AI 代理
  • 在 DataHub 中檢查資料血緣影響範圍，並追蹤遊戲折扣與發售資訊
  • 執行代理研究任務，並對 Sovereign Router 池中的模型供應方評分或路由
適用情境
適合助理需要隨選取得加密市場、錢包風險或 DeFi 資料、又不想申請 API 金鑰，且呼叫方能夠支付小額 USDC 按次費用的情境。也適合快速查詢 Gas 價格、探索 NFT 與代理，或進行 DataHub 影響分析。
執行需求
遠端 streamable HTTP 端點，無需安裝套件，未宣告 API 金鑰或環境變數。每個付費工具按次以美元計費（0.005 至 0.05 美元），透過 x402 流程在 Arc 上以 USDC 結算，因此呼叫方代理需要已入金的加密錢包並支援 x402 付款。
安裝前請注意
多數工具按次收費，自動化或重複呼叫會從代理錢包扣款 USDC。README 說明其自主代理錢包合約部署在 Arc 測試網並使用測試錢包，應視為實驗性專案。代幣風險評分與行情資料來自第三方，不應視為投資建議。部分工具會把地址或查詢傳送給 DexScreener、Magic Eden、rugcheck、DataHub 等外部服務。

安裝

在 SourceWeft 中

  1. 開啟 儀表板中的 X402 Gateway，將其新增到工作區。
  2. 為需要使用其工具的對話啟用該服務。

Web executable，透過 Streamable HTTP。 遠端服務在工作區中設定後即可從網頁執行環境執行。

交給代理程式安裝

把這段提示詞貼上到 Claude Code、Codex、Cursor 等代理程式，或 SourceWeft 對話中。代理程式會讀取該伺服器的安裝指南，先向你展示發布者、端點和登入方式，經你同意後再把它新增到你的客戶端。金鑰不會寫進任何命令。

閱讀 https://sourceweft.com/mcp/net.gentechlabs%2Fx402-gateway/install.md，並按其中說明把這個 MCP 伺服器接入我的客戶端。修改任何設定之前，先告訴我它的發布者、端點和登入方式，等我確認。不要把 API 金鑰寫進命令或我會提交的檔案；問我金鑰應從哪裡取得。

其他 MCP 客戶端

把它新增到你客戶端的 mcpServers 設定中。

Encode Club Programmable Money Hackathon — Circle × Arc
Track: Agentic Economy — AI agents that hold wallets, pay and transact autonomously in USDC Repo (public): https://github.com/Gentech-Labs/programmable-money-x402

The Problem

AI agents need to pay for APIs, compute, and data — but there's no standard way to do it programmatically. Every integration means manual API keys, subscriptions, or custom payment flows. Real agent autonomy requires programmable money.

The Solution

x402 on Arc — a payment gateway that bridges Circle's USDC infrastructure with the HTTP 402 Payment Required standard:

  1. An agent calls an API → gets HTTP 402 with payment requirements
  2. The agent pays USDC on Arc (sub-second settlement, USDC fees)
  3. Access is granted — no API keys, no signups, no human in the loop

This is programmable money for the agent economy.

Architecture

Agent → HTTP Request → x402 Middleware → HTTP 402 + Arc USDC invoice           ↓                                        ↓    Access Granted  ←  Payment Verified  ←  Agent pays USDC on Arc

Track Focus

Agentic Economy — AI agents hold wallets on Arc, pay for services in USDC autonomously, using Circle's stablecoin-native L1 for sub-second settlement.

Components

  • x402 Gateway — middleware that drops into any API, handles 402 → payment → access
  • Arc Settlement Layer — USDC transfers via Circle's infrastructure on Arc
  • Agent SDK — one function call for any agent to pay x402 APIs
  • Playground — test transactions, manage wallets, see the flow live

Why Arc + Circle

Arc is built for this — USDC as the native fee token, sub-second finality, and programmable wallet infrastructure. x402 on Arc means agents settle payments in the same block they're requested.

Deployment (LIVE on Arc testnet)

ArcAgentWallet.sol — autonomous agent wallet contract — deployed and verified on-chain:

What the deployed contract does: the agent wallet autonomously holds USDC, can be funded by any party, and executes agent-initiated transfers with a safety timeout — programmable money for agents, live on Circle's Arc L1.
