agentmeter-sdk 0.1.0

Track LLM costs per user. Open source SDK for AgentMeter.

AgentMeter SDK

Track LLM costs per user. The official Python SDK for AgentMeter.

AgentMeter automatically tracks token usage across OpenAI and Anthropic API calls, attributes costs to individual users, and reports them to your AgentMeter dashboard.

Installation

pip install agentmeter-sdk

With provider-specific extras:

pip install agentmeter-sdk[openai]
pip install agentmeter-sdk[anthropic]
pip install agentmeter-sdk[all]

Quick Start

import agentmeter

# Initialize before creating any LLM clients
agentmeter.init(api_key="am_live_xxx")

from openai import OpenAI
client = OpenAI()

# Wrap LLM calls with identify() to attribute usage to a user
with agentmeter.identify(user_id="user_123"):
    response = client.chat.completions.create(
        model="gpt-4o",
        messages=[{"role": "user", "content": "Hello!"}],
    )

That's it. Token usage is automatically captured and sent to your AgentMeter dashboard.

Usage

Initialization

Call agentmeter.init() before creating any LLM client instances. This patches the OpenAI and Anthropic libraries to capture usage data.

agentmeter.init(
    api_key="am_live_xxx",   # Required. Get this from your dashboard.
    enabled=True,            # Disable to turn off tracking (e.g. in tests).
    debug=False,             # Print events to console instead of sending them.
)

Identifying Users

Use identify() as a context manager or decorator to associate LLM calls with a user:

# Context manager
with agentmeter.identify(user_id="user_123"):
    response = client.chat.completions.create(...)

# Decorator
@agentmeter.identify(user_id="user_123")
def handle_request():
    return client.chat.completions.create(...)

You can optionally pass a session_id to group multiple LLM calls into a single session:

with agentmeter.identify(user_id="user_123", session_id="sess_abc"):
    response = client.chat.completions.create(...)
