# 通过网关进行 Coinbase 集市 AgentCore
<a name="payments-connect-bazaar"></a>

AgentCore 网关允许您连接到付费 MCP 服务器和 API 终端节点。你可以将Coinbase x402 Bazaar MCP服务器作为目标添加到网关中，以发现支持x402微交易的10,000多种现有付费MCP工具。
+ 服务器 URL — `https://api.cdp.coinbase.com/platform/v2/x402/discovery/mcp` 
+ 接受出站身份验证类型-无授权（默认）

## 将 Coinbase x402 Bazaar MCP 服务器添加到网关
<a name="_add_coinbase_x402_bazaar_mcp_server_to_a_gateway"></a>

**Example**  

1. 导航到 “**目标**” 部分。

1. （可选）更改生成的**目标名称**。

1. （可选）提供**目标描述**。

1. 对于**目标类型**，选择**集成。**

1. 选择 ** Coinbase x402 Bazaar。**

1. 跳过**出站身份验证配置**。“无授权” 是唯一支持的选项，默认情况下处于选中状态。

```
agentcore add gateway-target \
  --name CoinbaseTarget \
  --type mcp-server \
  --endpoint https://api.cdp.coinbase.com/platform/v2/x402/discovery/mcp \
  --gateway MyGateway

agentcore deploy
```

```
import boto3

agentcore_client = boto3.client('bedrock-agentcore-control')

target = agentcore_client.create_gateway_target(
    gatewayIdentifier="your-gateway-id",
    name="Coinbasex402BazaarTarget",
    description="Coinbase x402 Bazaar MCP server for paid API discovery",

配置 Bazaar 目标后，您的代理可以通过网关发现并呼叫付费的 x402 终端节点。当终端节点返回 HTTP 402 时， AgentCore 如果您在代理中配置了支付插件 (Strands) 或中间件 ()，则付款会自动处理付款流程。LangGraph要了解更多信息，请参阅[框架集成。](payments-framework-integrations.md)

要设置处理付款所需的付款管理器和连接器，请参阅[创建付款管理器和连接器](payments-create-manager.md)。
