概覽

AI 產生的概覽

遠端 MCP 伺服器,提供四個 x402 付費 API:文字分析、標題鉤子評分、英波翻譯品管與 RAWG 遊戲資料。

可以做什麼
  • 分析文字:字數統計、Flesch 可讀性、文字系統組成與關鍵詞
  • 依發布方規則為遊戲標題或鉤子打 0–100 分
  • 檢查英波互譯品質並給 0–100 分,涵蓋數字與實體保留、文字純淨度、未翻譯片段
  • 查詢 RAWG 即時遊戲資料:發售日期、評分、Metacritic、平台、類型
  • 每次呼叫只回傳閘道即時的 402 付款要求作為錯誤結果,不會回傳資源本身
適用情境
適合需要快速、確定性的文字指標、標題評分、翻譯品管或遊戲資料,且使用者願意按次以 Base 上的 USDC 支付數美分的場合。不適合需要免費、無限次或離線使用的工作流程。
執行需求
遠端 streamable HTTP 端點,不需帳號或 API 金鑰。每次付費呼叫需以 Base 上的 USDC 透過 x402 付款,即簽署 EIP-3009 授權並在 REST 路由上以 X-PAYMENT 標頭送出;MCP 傳輸本身無法攜帶該標頭,付款須在 MCP 呼叫之外完成。需要可連線閘道的網路,以及持有 USDC 的 Base 錢包。
安裝前請注意
每次工具呼叫都要付費(每次 0.01–0.03 USDC),款項直接結算至發布方錢包,四個服務皆無免費額度。付款需以錢包私鑰簽署 EIP-3009 授權,應嚴格控制支出上限。送出的文字、標題與譯文會傳送至第三方閘道,遊戲資料轉自 RAWG。

安裝

在 SourceWeft 中

  1. 開啟 儀表板中的 369 Meter — pay-per-call APIs for agents (x402),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/io.github.369369yz-collab%2Fmeter369/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。

README

369 Meter — pay-per-call APIs for agents (x402)

Four pay-per-call APIs for agents, one rail: x402 (v1, "exact" scheme, USDC on Base), settling directly to the publisher's wallet. No accounts, no API keys, no checkout — call a route, get an HTTP 402 with payment requirements, pay, get the resource.

Live gateway: https://369yz.pythonanywhere.com/meter/ Health (free): https://369yz.pythonanywhere.com/meter/health PayTo (Base): 0xA0A1ff293EF2FF051121674c8eAAd69570b25e6c Facilitator: payai-public · every 402 declares the Bazaar discovery extension.

How to pay (x402)

bash
# 1. Call without payment -> HTTP 402 + x402 payment requirementscurl -s -X POST https://369yz.pythonanywhere.com/meter/v1/text/analyze \  -H 'Content-Type: application/json' -d '{"text":"your text"}'
# 2. Sign an EIP-3009 USDC authorization for the amount in#    accepts[0].maxAmountRequired and retry with the X-PAYMENT header.#    The resource is served only after the facilitator confirms settlement.

MCP

mcp_adapter.py (this repo, stdlib-only Python) exposes the same four services as MCP tools for directory discovery:

  • stdio: python3 mcp_adapter.py
  • streamable HTTP: mount application in any WSGI server (POST JSON-RPC).

tools/list and initialize are free. Because an MCP transport cannot carry an X-PAYMENT header, tools/call performs the real gateway call and returns the gateway's live 402 payment requirements as an MCP error result — it never serves an unpaid resource. Pay over the x402 rail on the REST route above.

Directory manifests in this repo: server.json (Official MCP Registry, name io.github.369369yz-collab/meter369), glama.json (Glama claim), openapi.json (the REST API spec, prices verified against the live 402s).

Also listed via

  • api.market — the same REST API (openapi.json); api.market auto-generates an MCP endpoint for listed APIs.
  • PayAPI Market — x402 directory (listed 2026-10-25; a $0.02 USDC canary payment from their verification has landed on-chain).
