​
1. Installation

Install the traceAI and Haystack packages. 
pip install traceAI-haystack haystack-ai trafilatura

​
2. Set Environment Variables

Set up your environment variables to authenticate with FutureAGI. 
import os

os.environ["OPENAI_API_KEY"] = "your-openai-api-key"
os.environ["FI_API_KEY"] = "your-futureagi-api-key"
os.environ["FI_SECRET_KEY"] = "your-futureagi-secret-key"

​
3. Initialize Trace Provider

Set up the trace provider to create a new project in FutureAGI, establish telemetry data pipelines . 
from fi_instrumentation import register
from fi_instrumentation.fi_types import ProjectType

trace_provider = register(
    project_type=ProjectType.OBSERVE,
    project_name="haystack_project",
)

​
4. Instrument your Project

Initialize the Haystack instrumentor to enable automatic tracing. 
from traceai_haystack import HaystackInstrumentor

HaystackInstrumentor().instrument(tracer_provider=trace_provider)

​
5. Create Haystack Components

Set up your Haystack components as you normally would. Our Instrumentor will automatically trace and send the telemetry data to our platform.
