如果您的代理部署时配置了支付功能，请在付款上下文中调用该代理，x402 拦截器会自动处理付款处理：
agentcore invoke \
--prompt "Access the premium endpoint at https://example-x402-merchant.com/paid-api" \
--payment-instrument-id <INSTRUMENT_ID> \
--auto-session \
--payment-user-id user@example.com
要使用显式会话而不是自动创建会话，请执行以下操作：
agentcore invoke \
--prompt "Access the premium endpoint at https://example-x402-merchant.com/paid-api" \
--payment-instrument-id <INSTRUMENT_ID> \
--payment-session-id <SESSION_ID> \
--payment-user-id user@example.com
部署的代理的 x402 插件拦截 HTTP 402 响应、呼叫ProcessPayment，并使用证据重试请求。需要 AgentCore CLI 版本 0.19.0 或更高版本。
- AgentCore SDK

使用该PaymentManager类在任何代理框架内手动生成付款标题：
import uuid
from bedrock_agentcore.payments import PaymentManager
manager = PaymentManager(
payment_manager_arn=mgr["paymentManagerArn"],
region_name="us-west-2"
)
# When you receive a 402 response, generate payment proof
payment_required_request = {
"statusCode": 402,
"headers": payment_required["headers"],
"body": payment_required["body"],
}
payment_proof_headers = manager.generate_payment_header(
user_id="test-user-123",
payment_instrument_id=instrument["paymentInstrumentId"],
payment_session_id=session["paymentSessionId"],
payment_required_request=payment_required_request,
client_token=str(uuid.uuid4()),
)
payment_proof_headers包含付款证明标题。在向付费端点重试请求时，请包含此标头。您也可以调用process_payment方法PaymentManager来更好地控制输入。
