Langtrace

Integrating Agno with Langtrace

Langtrace traces and monitors the model calls made by an Agno agent.

Prerequisites

1. Install Dependencies

   Ensure you have the necessary package installed:

   uv pip install agno openai yfinance langtrace-python-sdk

2. Create a Langtrace Account

   • Sign up for an account at Langtrace.
   • Obtain your API key from the Langtrace dashboard.

3. Set Environment Variables

   Configure your environment with the Langtrace and OpenAI API keys:

   export LANGTRACE_API_KEY="your-key"
   export OPENAI_API_KEY="your-key"

Sending Traces to Langtrace

Instrument your Agno agent with Langtrace.

from langtrace_python_sdk import langtrace

langtrace.init()

from agno.agent import Agent
from agno.models.openai import OpenAIResponses
from agno.tools.yfinance import YFinanceTools

agent = Agent(
    name="Stock Price Agent",
    model=OpenAIResponses(id="gpt-5.2"),
    tools=[YFinanceTools()],
    instructions="You are a stock price agent. Answer questions in the style of a stock analyst.",
    debug_mode=True,
)

agent.print_response("What is the current price of Tesla?")

Initialize Langtrace before importing Agno or OpenAI modules. This lets Langtrace instrument the model client when it loads.
