概览

AI 生成的概览

远程 MCP 服务器,提供四个 x402 付费接口:文本分析、钩子评分、英波翻译质检和 RAWG 游戏资料。

可以做什么
  • 分析文本:字数统计、Flesch 可读性、文字系统构成和关键词
  • 按发布方规则为游戏标题或钩子打 0–100 分
  • 检查英波互译质量,给出 0–100 分,涵盖数字与实体保留、文字纯净度、未翻译片段
  • 查询 RAWG 实时游戏资料:发售日期、评分、Metacritic、平台、类型
  • 每次调用只返回网关实时的 402 付款要求作为错误结果,不返回资源本身
适用场景
适合需要快速、确定性的文本指标、标题评分、翻译质检或游戏资料,且用户愿意按次以 Base 上的 USDC 支付几分钱的场景。不适合需要免费、无限次或离线使用的工作流。
运行要求
远程 streamable HTTP 端点,无需账号或 API 密钥。每次付费调用需以 Base 上的 USDC 通过 x402 付款,即签署 EIP-3009 授权并在 REST 路由上通过 X-PAYMENT 请求头发送;MCP 传输本身无法携带该请求头,付款需在 MCP 调用之外完成。需要能访问网关的网络和持有 USDC 的 Base 钱包。
安装前请注意
每次工具调用都要付费(每次 0.01–0.03 USDC),款项直接结算到发布方钱包,四个服务均无免费额度。付款需用钱包私钥签署 EIP-3009 授权,应严格控制支出上限。提交的文本、标题和译文会发送到第三方网关,游戏资料转自 RAWG。

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).

MIT — see LICENSE. The gateway service itself is operated by VeritasWorks; this repo publishes the adapter and the directory manifests.
