Prerequisites

前置条件

A crypto wallet funded with USDC is required to use paid endpoints. Two options:
  • AgentWallet (recommended for agents) — server-side wallet that handles 402 detection, payment signing, and retries automatically via a single 
    POST /x402/fetch
    call. No private key management needed on your side.
  • Self-managed wallet — any EVM wallet (Base) or Solana wallet with USDC. You sign x402 payment headers directly.
使用付费端点需要一个充值了USDC的加密货币钱包，有两种选择：
  • AgentWallet（推荐Agent使用） —— 服务器端钱包，通过单次
    POST /x402/fetch
    调用自动处理402检测、支付签名和重试。无需您这边管理私钥。
  • 自管钱包 —— 任何支持USDC的EVM钱包（Base链）或Solana钱包。您需要直接签署x402支付头。

Quick Start

快速开始

  1. Set up a wallet — create an AgentWallet or fund your own wallet with USDC
  2. Discover services: 
    GET https://registry.mcpay.tech/api/services
  3. Read service docs: 
    GET https://registry.mcpay.tech/api/service/{slug}/skill.md
  4. Check pricing: 
    GET https://registry.mcpay.tech/api/pricing
  5. Make a paid request — via AgentWallet's 
    /x402/fetch
    or directly with x402 headers (see Payment Protocol below)
  1. 设置钱包 —— 创建AgentWallet，或为您自己的钱包充值USDC
  2. 发现服务：
    GET https://registry.mcpay.tech/api/services
  3. 查看服务文档：
    GET https://registry.mcpay.tech/api/service/{slug}/skill.md
  4. 查看定价：
    GET https://registry.mcpay.tech/api/pricing
  5. 发起付费请求 —— 通过AgentWallet的
    /x402/fetch
    接口，或直接携带x402头发起请求（详见下方支付协议）

Payment Protocol (x402)

支付协议（x402）

All paid endpoints use the x402 payment protocol. No API keys needed.
Flow:
  1. Call any paid endpoint without a payment header
  2. Receive 
    402 Payment Required
    with a 
    PAYMENT-REQUIRED
    header (Base64 JSON with price, network, payTo address)
  3. Sign a payment for the requested amount on your chosen network
  4. Retry the same request with the 
    PAYMENT-SIGNATURE
    header
  5. Receive the response plus a 
    PAYMENT-RESPONSE
    confirmation header
Failed requests are automatically refunded.

    响应，其中包含
    PAYMENT-REQUIRED
    头（Base64编码的JSON，包含价格、网络、收款地址）
  3. 在您选择的网络上签署对应金额的支付授权
  4. 携带
    PAYMENT-SIGNATURE
    头重试同一请求
  5. 收到响应以及

Agent Integration

Agent集成

With AgentWallet (recommended)

使用AgentWallet（推荐）

AgentWallet is a server-side wallet for AI agents. It manages keys, balances, and x402 payment signing so agents don't need to handle crypto directly.
  1. Authenticate with AgentWallet (email OTP → API token)
  2. Fund your wallet with USDC on Base or Solana
  3. Call any Frames Registry endpoint through AgentWallet's proxy:
POST https://agentwallet.mcpay.tech/x402/fetch
{
  "url": "https://registry.mcpay.tech/api/service/twitter/api/search-tweets",
  "method": "POST",
  "body": { "query": "AI agents" }
}
AgentWallet detects the 402 response, signs payment, and retries automatically.
AgentWallet是面向AI Agent的服务器端钱包。它管理密钥、余额和x402支付签名，让Agent无需直接处理加密货币。
  1. 通过AgentWallet认证（邮箱OTP → API令牌）
  2. 在Base或Solana网络为您的钱包充值USDC
  3. 通过AgentWallet的代理调用任意Frames Registry端点：
POST https://agentwallet.mcpay.tech/x402/fetch
{
  "url": "https://registry.mcpay.tech/api/service/twitter/api/search-tweets",
  "method": "POST",
  "body": { "query": "AI agents" }
}
AgentWallet会自动检测402响应、签署支付并重试请求。

Direct x402 (self-managed wallet)

直接使用x402（自管钱包）

Requires an EVM or Solana wallet with USDC and the ability to sign EIP-3009 or SPL transfers.
  1. Make the request to the paid endpoint
  2. Parse the 
    PAYMENT-REQUIRED
    header from the 402 response (Base64 JSON with price, network, payTo)
  3. Sign a payment authorization for the exact amount
  4. Retry with the 
    PAYMENT-SIGNATURE
    header
需要一个充值了USDC的EVM或Solana钱包，并且具备签署EIP-3009或SPL转账的能力。
  1. 向付费端点发起请求
  2. 从402响应中解析
    PAYMENT-REQUIRED
    头（Base64编码的JSON，包含价格、网络、收款地址）
  3. 签署对应金额的支付授权
  4. 携带
    PAYMENT-SIGNATURE
    头重试请求
