+# Opik Tracing for Pipecat
+
+This demo showcases OpenTelemetry tracing integration for Pipecat services using Opik, allowing you to visualize and analyze LLM traces, service calls, performance metrics, and dependencies.
+
+> **Note**: Opik supports HTTP/JSON OpenTelemetry traces only (no logs or metrics).
+
+## Setup Instructions
+
+### 1. Get Your Opik API Key
+
+Sign up or log in at [https://www.comet.com/opik](https://www.comet.com/opik) to get your API key and workspace name.
+
+### 2. Environment Configuration
+
+Create a `.env` file with your API keys and Opik configuration:
+
+```
+# Enable tracing
+ENABLE_TRACING=true
+
+# OTLP endpoint (defaults to Opik Cloud if not set)
+OTEL_EXPORTER_OTLP_ENDPOINT=https://www.comet.com/opik/api/v1/private/otel/v1/traces
+
+# Opik headers - Configure your API key, workspace, and project name
+OTEL_EXPORTER_OTLP_HEADERS=Authorization=your_opik_api_key,Comet-Workspace=your_workspace_name,projectName=your_project_name
+
+# Optional: Enable console output for debugging
+# OTEL_CONSOLE_EXPORT=true
+
+# Service API keys
+DEEPGRAM_API_KEY=your_key_here
+CARTESIA_API_KEY=your_key_here
+OPENAI_API_KEY=your_key_here
+```
+
+For self-hosted Opik installations, update the endpoint:
+```
+OTEL_EXPORTER_OTLP_ENDPOINT=http://<YOUR-OPIK-INSTANCE>/api/v1/private/otel/v1/traces
+```
+
+### 3. Install Dependencies
+
+```bash
+pip install -r requirements.txt
+```
+
+> **Important**: Use the HTTP exporter (`opentelemetry-exporter-otlp-proto-http`), not the GRPC exporter. Opik only supports HTTP transport.
+
+### 4. Run the Demo
+
+```bash
+python bot.py
+```
+
+### 5. View Traces in Opik
+
+Open your browser to [https://www.comet.com/opik](https://www.comet.com/opik) and navigate to your project to view traces and analyze your LLM interactions.
+
+## Opik-Specific Configuration
+
+In the `bot.py` file, note the HTTP exporter configuration:
+
+```python
+from opentelemetry.exporter.otlp.proto.http.trace_exporter import OTLPSpanExporter
+
+# Create the exporter for Opik (HTTP/JSON only)
+# Headers are configured via OTEL_EXPORTER_OTLP_HEADERS environment variable
+otlp_exporter = OTLPSpanExporter(
+    endpoint=os.getenv(
+        "OTEL_EXPORTER_OTLP_ENDPOINT",
+        "https://www.comet.com/opik/api/v1/private/otel/v1/traces"
+    ),
+)
+
+# Set up tracing with the exporter
+setup_tracing(
+    service_name="pipecat-demo",
+    exporter=otlp_exporter,
+    console_export=bool(os.getenv("OTEL_CONSOLE_EXPORT")),
+)
+```
+
+The OpenTelemetry SDK automatically reads headers from the `OTEL_EXPORTER_OTLP_HEADERS` environment variable.
+
+## Key Features
+
+- **HTTP/JSON Transport**: Opik uses HTTP transport for OpenTelemetry traces
+- **LLM-Focused**: Optimized for tracking and analyzing LLM interactions
+- **Required Headers**: 
+  - `Authorization`: Your Opik API key
+  - `projectName`: Your project name in Opik
+  - `Comet-Workspace`: Your workspace name (required for Comet-hosted installations)
+
+## Troubleshooting
+
+- **No Traces in Opik**: Verify your API key, workspace name, and project name are correct
+- **Authorization Errors**: Ensure your `OPIK_API_KEY` and `OPIK_WORKSPACE` are set correctly
+- **Connection Errors**: Check your network connectivity and endpoint URL
+- **Exporter Issues**: Try the Console exporter (`OTEL_CONSOLE_EXPORT=true`) to verify tracing works locally
