    )
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}")
```

| Classe d'erreur        | Declenchee quand                                |
| ---------------------- | ----------------------------------------------- |
| `AgentWallexError`     | Classe de base pour toutes les erreurs API      |
| `PolicyViolationError` | Transaction bloquee par le moteur de politiques |
| `AuthenticationError`  | Cle API invalide ou manquante                   |
| `NotFoundError`        | La ressource n'existe pas                       |
| `RateLimitError`       | Limite de debit depassee                        |

## Type hints

Le SDK Python inclut des type hints complets pour le support IDE et l'analyse statique :

```python theme={null}
from agentwallex.types import (
    Agent,
    Payment,
    Transaction,
    Policy,
    X402Session,
    WebhookEvent,
)
```

## Utilisation avec asyncio

Le SDK est async-first. Utilisez-le dans un contexte async :

```python theme={null}
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())
```
