概覽

AI 產生的概覽

遠端 MCP 伺服器，讓助理取得美國總經、公債、房貸、匯率、能源、加密與 SEC EDGAR 財務資料，並透過 x402 按次付費。

可以做什麼
取得 FRED 序列的目前值或指定日期值，例如公債殖利率、房貸利率、CPI、失業率、GDP 與能源價格，以及歐洲央行的 G10 匯率與歷史匯率序列。計算衍生指標：殖利率曲線利差、Sahm 規則衰退訊號與聯準會政策利差。呼叫預先組合的套件，涵蓋再融資訊號、購屋負擔能力、利率環境、房貸脈動、總經循環、匯率儀表板、能源，以及可直接放入提示詞的經濟背景簡報。取得 CoinGecko 的加密貨幣價格、歷史行情與市值前 20 名組合。查詢美國上市公司的 SEC EDGAR 基本面資料（營收、淨利、資產、權益、每股盈餘），並列出即將發布的 FRED 資料日期。
適用情境
適合助理需要目前或歷史美國經濟與市場資料來進行分析、評論或回答客戶問題時使用，也適合希望一次呼叫就取得多項指標、而非多次個別查詢的情境。
執行需求
遠端 streamable HTTP 端點；未宣告需要本機執行環境、API 金鑰或帳號。查詢透過 x402 按次計費，付費工具需要能在 Base 上支付 USDC 的錢包；部分工具標示為免費。
安裝前請注意
多數資料工具按次收費（例如 0.01、0.05、0.02 與 0.15 USDC），重複或組合呼叫會花費資金，建議設定支出上限。付款透過 Base 上的 x402 完成，涉及加密錢包。資料來自第三方（FRED、ECB、CoinGecko、SEC EDGAR），僅供參考，不構成投資建議。
