Afen Python SDK

Capture runtime errors and send them to an Afen instance.

• Automatic capture of unhandled exceptions via sys.excepthook
• Manual capture with optional context
• Async support
• Django middleware integration
• Python ≥ 3.8, zero heavy dependencies

Installation

pip install afen-client

Quick Start

from afen.client import AfenClient

client = AfenClient(
    api_url="http://localhost:3000",
    api_key="your-api-token",
    service_name="my-service",
)

That's it. A global sys.excepthook is registered automatically — all unhandled exceptions are forwarded to Afen without any further setup.

Manual Capture

try:
    process_payment(payload)
except Exception as e:
    client.capture(e, context={"order_id": payload["id"]})
    raise

Async Support

async def handler(request):
    try:
        await process_payment(payload)
    except Exception as e:
        await client.capture_async(e, context={"order_id": payload["id"]})
        raise

Disable Auto-Capture

client = AfenClient(
    api_url="http://localhost:3000",
    api_key="your-api-token",
    service_name="my-service",
    auto_capture=False,
)

Django Integration

# settings.py
MIDDLEWARE = [
    "afen.integrations.django.AfenMiddleware",
    ...
]

AFEN = {
    "API_URL": "http://localhost:3000",
    "API_KEY": "your-api-token",
    "SERVICE_NAME": "my-django-app",
}

Captures all unhandled Django exceptions and attaches request.path, request.method, and response status as context.

Configuration

Requirements

• Python ≥ 3.8
