revenium-middleware-anthropic 0.2.9

A Python library that meters Anthropic usage to Revenium.

🤖 Revenium Middleware for Anthropic

A middleware library for metering and monitoring Anthropic API usage in Python applications. 🐍✨

✨ Features

• 📊 Precise Usage Tracking: Monitor tokens, costs, and request counts across all Anthropic API endpoints
• 🔌 Seamless Integration: Drop-in middleware that works with minimal code changes
• ⚙️ Flexible Configuration: Customize metering behavior to suit your application needs

📥 Installation

pip install revenium-middleware-anthropic

🔧 Usage

🔄 Zero-Config Integration

Simply export your REVENIUM_METERING_API_KEY and import the middleware. Your Anthropic calls will be metered automatically:

import anthropic
import revenium_middleware_anthropic

client = anthropic.Anthropic()

message = client.messages.create(
    model="claude-3-7-sonnet-20250219",
    max_tokens=20000,
    temperature=1,
    messages=[
        {
            "role": "user",
            "content": [
                {
                    "type": "text",
                     "text": "What is the meaning of life, the universe and everything?",
                }
            ]
        }
    ]
)
print(message.content)

The middleware automatically intercepts Anthropic API calls and sends metering data to Revenium without requiring any changes to your existing code. Make sure to set the REVENIUM_METERING_API_KEY environment variable for authentication with the Revenium service.

📈 Enhanced Tracking with Metadata

For more granular usage tracking and detailed reporting, add the usage_metadata parameter:

import anthropic
import revenium_middleware_anthropic

client = anthropic.Anthropic()

message = client.messages.create(
    model="claude-3-7-sonnet-20250219",
    max_tokens=20000,
    temperature=1,
    messages=[
        {
            "role": "user",
            "content": [
                {
                    "type": "text",
                    "text": "What is the meaning of life, the universe and everything?",
                }
            ]
        }
    ],
    usage_metadata={
        "trace_id": "conv-28a7e9d4-1c3b-4e5f-8a9b-7d1e3f2c1b4a",
        "task_id": "chat-summary-af23c910",
        "task_type": "text-classification",
        "subscriber_email": "[e-mail]",
        "organization_id": "acme-corporation-12345",
        "subscription_id": "startup-plan-quarterly-2025-Q1",
        "product_id": "intelligent-document-processor-v3",
        "agent": "customer-support-assistant-v2",
    }
)
print(message.content)

🔄 Streaming Support

The middleware also supports Anthropic's streaming API. For streaming responses, use the usage_context to set metadata before making the streaming call. The middleware will automatically track token usage and send metering data when the stream completes.

import anthropic
from revenium_middleware_anthropic import usage_context

usage_context.set({
    "task_id": "task-41921",
    "agent": "network-traffic-analyzer",
    "subscriber_email": "[e-mail]",
    "organization_id": "devops-team-emea",
    "response_quality_score": 0.5,
})

with client.messages.stream(
    max_tokens=1024,
    messages=[{"role": "user", "content": "Hello, Claude"}],
    model="claude-3-5-sonnet-latest",
) as stream:
    for text in stream.text_stream:
        print("\n>>>" + text, end="", flush=True)

🏷️ Metadata Fields

The usage_metadata parameter supports the following fields:

Field	Description	Use Case
trace_id	Unique identifier for a conversation or session	Track multi-turn conversations
task_id	Identifier for a specific AI task	Group related API calls for a single task
task_type	Classification of the AI operation	Categorize usage by purpose (e.g., classification, summarization)
subscriber_email	The email address of the subscriber	Track usage by individual users
subscriber_credential_name	The name of the credential associated with the subscriber	Track usage by individual users
subscriber_credential	The credential associated with the subscriber	Track usage by individual users
organization_id	Customer or department identifier	Allocate costs to business units
subscription_id	Reference to a billing plan	Associate usage with specific subscriptions
product_id	The product or feature using AI	Track usage across different products
agent	Identifier for the specific AI agent	Compare performance across different AI agents
response_quality_score	The quality of the AI response (0..1)	Track AI response quality

All metadata fields are optional. Adding them enables more detailed reporting and analytics in Revenium.

🔄 Compatibility
