安装

pip install agentwallex
要求: Python 3.9+

客户端初始化

import os
from agentwallex import AgentWallex

aw = AgentWallex(
    api_key=os.environ["AGENTWALLEX_API_KEY"],
    environment="sandbox",  # "sandbox" or "production"
    timeout=30,             # Request timeout in seconds (default: 30)
)
参数类型默认值说明
api_keystr必填您的 API 密钥(awx_...
environmentstr"sandbox""sandbox""production"
base_urlstrNone自定义基础 URL(覆盖 environment)

Python SDK 是异步优先的。所有方法返回协程,需要使用 await。

代理

aw.agents.create()

创建一个带有 MPC 安全钱包的新代理。
agent = await aw.agents.create(
    name="my-agent",
    chain="eip155:8453",
    policies={
        "max_transaction_amount": "100",
        "daily_limit": "1000",
        "allowed_addresses": ["0x..."],
        "allowed_tokens": ["USDC"],
    },
    metadata={"team": "growth"},
)

print(f"Agent ID: {agent.id}")
print(f"Wallet: {agent.wallet.address}")

aw.agents.get(agent_id)

agent = await aw.agents.get("agent_abc123")

aw.agents.list()

result = await aw.agents.list(
    limit=20,
    offset=0,
    status="active",
)

for agent in result.agents:
    print(f"{agent.name}: {agent.wallet.address}")

aw.agents.freeze(agent_id) / aw.agents.unfreeze(agent_id)

# Freeze — immediate
await aw.agents.freeze("agent_abc123")

# Unfreeze — subject to 10-minute cool-down
await aw.agents.unfreeze("agent_abc123")

支付

aw.payments.send()

发送直接链上支付。
tx = await aw.payments.send(
    agent_id="agent_abc123",
    to="0xRecipientAddress",
    amount="50.00",
    token="USDC",
    memo="Payment for API access",
)

print(f"Hash: {tx.hash}")
print(f"Status: {tx.status}")
print(f"Fee: {tx.fee}")

aw.payments.get(transaction_id)

tx = await aw.payments.get("tx_xyz789")

aw.payments.list()

result = await aw.payments.list(
    agent_id="agent_abc123",
    limit=50,
    status="confirmed",
)

for tx in result.transactions:
    print(f"{tx.amount} {tx.token} -> {tx.status}")

x402 微支付

aw.x402.create_session()

session = await aw.x402.create_session(
    agent_id="agent_abc123",
    budget_limit="100.00",
    chain="eip155:84532",
    ttl_seconds=3600,
    allowed_urls=["https://paid-api.example.com/v1/data"],
)

aw.x402.check()

info = await aw.x402.check(url="https://paid-api.example.com/v1/data")

aw.x402.pay()

result = await aw.x402.pay(
    agent_id="agent_abc123",
    target_url="https://paid-api.example.com/v1/data",
    session_id=session.id,
    chain="eip155:84532",
)

aw.x402.session_pay(session_id, target_url)

await aw.x402.session_pay(
    session.id,
    target_url="https://paid-api.example.com/v1/data",
)

aw.x402.http_interceptor()

创建一个拦截器,自动处理 x402 v2 挑战:
fetch_with_payment = aw.x402.http_interceptor(
    agent_id="agent_abc123",
    chain="eip155:84532",
)

# Automatically handles 402 -> pay -> retry
response = await fetch_with_payment("https://paid-api.example.com/v1/data")
data = response.json()

策略

aw.policies.update()

await aw.policies.update(
    "agent_abc123",
    max_transaction_amount="200",
    daily_limit="2000",
    allowed_addresses=["0xAddr1", "0xAddr2"],
    velocity_limit={"max_count": 100, "window_seconds": 3600},
)

aw.policies.get(agent_id)

policies = await aw.policies.get("agent_abc123")

aw.policies.apply_template()

await aw.policies.apply_template("agent_abc123", "conservative")

Webhooks

aw.webhooks.create()

webhook = await aw.webhooks.create(
    url="https://your-app.com/webhooks/agentwallex",
    events=[
        "payment.completed",
        "payment.failed",
        "agent.frozen",
        "policy.violated",
    ],
    secret="whsec_your_signing_secret",
)

错误处理

from agentwallex import AgentWallexError, PolicyViolationError

try:
    tx = await aw.payments.send(
        agent_id="agent_abc123",
        to="0xRecipientAddress",
        amount="50.00",
        token="USDC",
    )
except PolicyViolationError as e:
    print(f"Policy violated: {e.rule}")
    print(f"Details: {e.message}")
except AgentWallexError as e:
    print(f"API error [{e.code}]: {e.message}")
except Exception as e:
    print(f"Unexpected error: {e}")
错误类触发条件
AgentWallexError所有 API 错误的基类
PolicyViolationError交易被策略引擎阻止
AuthenticationErrorAPI 密钥无效或缺失
NotFoundError资源不存在
RateLimitError超过速率限制

类型提示

Python SDK 包含完整的类型提示,支持 IDE 补全和静态分析:
from agentwallex.types import (
    Agent,
    Payment,
    Transaction,
    Policy,
    X402Session,
    WebhookEvent,
)

与 asyncio 配合使用

SDK 是异步优先的。在异步上下文中使用:
import asyncio
from agentwallex import AgentWallex

async def main():
    aw = AgentWallex(api_key="awx_your_api_key", environment="sandbox")

    agent = await aw.agents.create(
        name="my-agent",
        chain="eip155:84532",
    )
    print(f"Created agent: {agent.id}")

asyncio.run(main())
