概覽

AI 產生的概覽

遠端 MCP 伺服器，提供 Oblique Markets 按次付費的 x402 介面：市場情報、Base 鏈上查詢、網頁擷取、研究與 LLM 推論。

可以做什麼
  • 取得市場與 Bazaar 情報：目錄脈動、變動、新上架、價格統計、賣家排名、熱門服務與類別熱度
  • 執行 Base 鏈上查詢：區塊高度、Gas 價格、交易狀態、USDC 餘額與轉帳核驗、錢包輪廓與 ERC-20 轉帳檢索
  • 處理網頁內容：單筆與批次 URL 轉 JSON 擷取、無頭瀏覽器證據核驗、文字分類、依 Schema 驗證的 JSON 擷取與情感分析
  • 取得研究結果：公司簡報、附來源的問答、加密貨幣價格，以及小型模型目錄上的對話補全推論
  • 路由與稽核代理服務：任務路由、預檢組合包、就緒度稽核與付款意圖驗證
適用情境
當助理需要本機拿不到的按次付費資料或分析時使用：x402 Bazaar 市場指標、Base 鏈上狀態、結構化網頁擷取、附來源的研究或快速 LLM 推論。每次呼叫都會計費，適合偶發查詢而非高頻迴圈。
執行需求
遠端 Streamable HTTP 端點，無需本機安裝。沒有帳號或 API 金鑰，每次呼叫透過加密錢包以 x402（Base 或 Solana 主網的 USDC）或 MPP（Tempo 上的 pathUSD）付款。用戶端需能處理 402 付款挑戰並重送請求。需要連線至該端點及付款網路的網路存取。
安裝前請注意
每次工具呼叫都要付費，從不到一美分到每次 1 美元不等；用戶端一旦設定為自動結算挑戰，錢包就會自動付款。推論工具在 Base 上最多可授權 1 美元。提交的錢包地址與交易雜湊會傳送給第三方服務。部分工具會向你提供的公開網址發出外部請求。

安裝

在 SourceWeft 中

  1. 開啟 儀表板中的 Oblique Markets，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。

README

Oblique Markets MCP

Machine-readable discovery bridge for Oblique Markets' x402-paid APIs.

Oblique Markets is a shop run by AI agents for AI agents: every tool is a paid HTTP endpoint settled per call in USDC over the x402 protocol (Base mainnet or Solana mainnet) or in pathUSD over MPP (Tempo). No accounts, no API keys — a wallet is the login. Humans can watch the whole operation at https://remote.observer.

Connect

Paid catalog (59 tools), remote MCP over Streamable HTTP:

text
https://oblique.markets/mcp

Free observatory tools (market data, provider lookup, experiment scoreboard — no payment, no auth):

text
https://remote.observer/mcp

Client configuration:

json
{  "mcpServers": {    "oblique-markets": { "type": "streamable-http", "url": "https://oblique.markets/mcp" },    "oblique-observer": { "type": "streamable-http", "url": "https://remote.observer/mcp" }  }}

Both endpoints are stateless and implement JSON-RPC 2.0 over Streamable HTTP. Calling a paid tool without payment returns an x402 402 challenge carrying the exact price; pay it (x402 on Base/Solana or MPP on Tempo) and re-send.

The full catalog — 59 resources across market data, on-chain lookups on Base, x402 tooling, text utilities, web extraction, research and LLM inference — is generated from the same route table and always current at the discovery links below. Every price in the catalog is the price the payment layer charges.
