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.chico10117%2Fx402-preflight/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

x402 Preflight — public documentation

Documentation only. This repository holds the public, citable material for x402 Preflight, a read-only launch-diagnostics service for x402 endpoints (https://x402.chikocorp.com).

The service code is private; nothing in this repository is required to run it, and no payment logic, credentials or infrastructure configuration belongs here.

What the service does

It reads the live 402 challenge your endpoint serves and compares it with what the endpoint advertises — price, network, asset, receiver, scheme — plus discovery metadata, input schemas, CORS, redirects and cache behaviour, and returns findings with evidence. It never connects a wallet, signs nothing, and makes no purchase on the target.

Free check (no account, no wallet)

bash
curl -s -X POST https://x402.chikocorp.com/api/preflight/inspect \  -H 'content-type: application/json' \  -d '{"resource_url":"https://your-api.example.com/resource","method":"GET"}'

Machine-readable manifests

Everything a registry, directory or agent needs to index this server without filling a form:

filefor
server.jsonofficial MCP registry manifest (streamable HTTP remote)
glama.jsonGlama maintainer claim
SKILL.mdagent skill: tools, inputs, prices and boundaries
gemini-extension.jsonGemini CLI extension pointing at https://x402.chikocorp.com/mcp

Live equivalents served by the service: /llms.txt, /mcp and /.well-known/x402.json.

Contents

  • docs/ — short answers: what x402 is, how to add it, and how to tell whether an endpoint really charges.
  • guides/x402scan-discovery.md — discovery requirements for catalogue listings (OpenAPI as the canonical contract).
  • guides/bazaar-listing-verification.md — how a Bazaar listing is verified and what the catalogue evidence says.
  • reference/ — mirrors of the live public artifacts (llms.txt, openapi.json).

Canonical source

The rendered pages live at https://x402.chikocorp.com/docs/. If this repository and the site disagree, the live service wins — the runtime 402 is the authoritative contract.

Contributing

Corrections and additions are welcome: see CONTRIBUTING.md. Keep claims verifiable — a finding without a reproducible command is not documentation.

inspect_x402_endpoint

Free x402 Endpoint Check

Free endpoint check for API developers launching or debugging x402. Inspect your live payment challenge and caller-selected comparison policy without sending payment credentials. ALLOW and BLOCK are policy decisions, not launch certification; a price-limit BLOCK does not establish a broken integration. Buyer-side inspection remains available.

audit_x402_endpoint

x402 Technical Audit

Technical audit for API developers launching or debugging x402. Returns deeper read-only evidence of payment configuration, schemas, redirects, CORS, cache behavior, OpenAPI, llms.txt, agent metadata, and x402 discovery consistency. Requires an explicitly authorized x402 purchase; does not test settlement, paid delivery, or actual marketplace indexing.

order_x402_remediation

Order x402 Diagnostic Report

Diagnostic report for API developers launching or debugging x402. An explicitly authorized x402 purchase creates a durable order for asynchronous findings, evidence, and prioritized fix recommendations in JSON/Markdown. The receipt is not the completed report. No implementation, human consultation, target payment, deployment, or guaranteed marketplace indexing.
