概览

AI 生成的概览

远程 x402 付费网关，提供 GPT-5.5/5.6 对话补全和大量付费智能体报告工具，按请求以 Base 或 Solana 上的 USDC 计费。

可以做什么: 运行 GPT-5.5、GPT-5.6 对话补全，以及按用量扣减预付余额的对话路由
检查服务状态，并用低成本支付探测为预付余额充值
生成 x402 运营类付费方案：买方支付执行手册、钱包激活、事件响应、支出模拟与资金政策
生成合规与财务类付费材料：采购评估档案、收据记账、税务对账、SOC 2 控制证据与收入分成账本
生成上线与安全类付费评审：MCP 上线审计、合约测试套件、红队简报、权益网关与部署方案
适用场景: 当你需要一个无需 API 密钥的 OpenAI 兼容对话模型，并愿意按请求用 USDC 付费时适用；也适用于需要为运营或采购 x402 付费 API 与 MCP 服务生成规划、审计类文档的场景。
运行要求: 通过 streamable HTTP 连接的远程 MCP 端点；未声明需要账号、API 密钥或环境变量。每次工具调用都需按请求以 x402 精确 USDC 在 Base 或 Solana 上付费，因此需要已充值的钱包或支持 x402 的客户端。需要能访问服务商主机的网络。

安装前请注意

每次工具调用都产生真实费用，从约 0.002 美元到约 25 美元不等，且价格标称为实时可变。付款为公链上的 USDC，未说明可退款。服务商并非 OpenAI，模型为第三方兼容路由。README 提醒切勿将私钥、助记词、支付头或 API 密钥粘贴到任何网站、聊天、日志或远程服务中。

安装

在 SourceWeft 中

打开控制台中的 GPT55 Model Gateway，将其添加到工作区。
为需要使用其工具的对话启用该服务。

README

x402 GPT API | GPT-5.6 Luna Base USDC Gateway

GPT55 x402 Gateway is the canonical buyer-owned Base USDC entry for this repository.

GPT55 is an x402 GPT API gateway: it provides an OpenAI-compatible GPT-5.6 Luna Standard result for $0.00293 USDC on Base. This is a compatible gateway, not an OpenAI-operated product. Buyers can pay one request from a browser wallet without handing over a private key, or use the quote-first agent fallback client when a wallet UI is unavailable.

The focused search topic is x402 GPT API / GPT API with USDC on Base: one POST request, one live quote, and one response. The canonical buyer path and complete integration guide are below.

The EVM Wallet Balance Snapshot remains available as a separate utility alternative; it is not the model product.

Canonical service entry:

Lowest-Friction First Payment

When validating a buyer-owned wallet or x402 client, start with the deterministic translate settlement canary before buying a model call or a larger pack:

Buyer guide: https://gpt55.558686.xyz/x402/translate-first-purchase
Paid route: POST https://gpt55.558686.xyz/v1/tools/translate
Quote-only command: ROUTE_ID=translate-canary MAX_USDC=0.00293 node first-payment-client.mjs

The client is quote-only by default. It verifies the live amount, Base network, USDC asset, merchant address, and same-request retry contract before an operator explicitly opts into payment. A successful canary is the smallest real payment test; Standard chat is the next step for a useful GPT-5.6 Luna response.

Agent Fallback

The buyer client is quote-only by default. Its local policies pin the exact URL, HTTP method, amount, Base network, canonical Base USDC contract, and merchant address for both Wallet and Standard. Remote catalogs are discovery metadata only. The client does not sign or pay unless the operator explicitly sets PAY_REAL_X402=1 and provides a wallet key in the operator-controlled process.

Never paste a private key, seed phrase, payment header, API key, or exchange credential into a website, chat, issue, log, or remote service.

Quote-Only Check

bash

git clone https://github.com/wangletiand/gpt55-x402-gateway.gitcd gpt55-x402-gatewaynpm installROUTE_ID=standard MAX_USDC=0.00293 npm run first-payment:quote

git clone https://github.com/wangletiand/gpt55-x402-gateway.gitcd gpt55-x402-gatewaynpm installROUTE_ID=standard MAX_USDC=0.00293 npm run first-payment:quote

The command remains quote-only unless real payment is explicitly enabled. Generated evidence files and .env files are ignored by Git.

The live quote is authoritative immediately before any payment. For an OpenAI-compatible request, send the same JSON body to /v1/chat/completions/standard after the x402 client returns a valid paid retry. The public service hub includes the browser-wallet flow and a link to the agent fallback client.

Local MCP Wrapper

The wrapper exposes one local read-only directory tool. It does not proxy MCP tool calls, custody funds, store wallet keys, or execute payments.

Repository Scope

This public repository intentionally contains only the maintained runtime wrapper, buyer safety client, tests, and concise documentation. Operational logs, payment evidence, wallet files, credentials, internal channel ledgers, and bulk submission automation are excluded.

Support and Security

For security reports, follow SECURITY.md. Do not include secrets or wallet material in a report.
