connexity 1.0.1

A Python client for Connexity API.

Connexity SDK for Pipecat

A Python SDK for tracking and analyzing voice AI call sessions with Pipecat. Provides frame observers for Twilio and Daily.co integrations to capture conversation data, latency metrics, and call analytics.

Installation

pip install connexity

Version

from connexity import __version__
print(__version__)

Usage

Twilio Observer

Use ConnexityTwilioObserver for Twilio-based telephony calls:

from pipecat.audio.vad.vad_analyzer import VADParams
from connexity.pipecat.twilio import ConnexityTwilioObserver
from connexity.utils.logging_config import LogLevel
from twilio.rest import Client

# Configure VAD parameters
vad_params = VADParams(
    confidence=0.5,
    min_volume=0.6,
    start_secs=0.2,
    stop_secs=0.8,
)

# Initialize Twilio client and start recording
twilio_client = Client(account_sid, auth_token)
twilio_client.calls(call_sid).recordings.create()

# Create and initialize the observer
observer = ConnexityTwilioObserver()
await observer.initialize(
    sid=call_sid,                         # Twilio Call SID
    agent_id="YOUR_AGENT_ID",             # Your Connexity agent ID
    api_key="YOUR_CONNEXITY_API_KEY",     # Your Connexity API key
    vad_params=vad_params,                # VAD configuration
    run_mode="production",                # "development" or "production"
    vad_analyzer="silero",                # VAD engine name
    twilio_client=twilio_client,          # Twilio REST client instance
    log_level=LogLevel.INFO,              # Optional: DEBUG, INFO, WARNING, ERROR, CRITICAL
    latency_threshold_ms=4000.0,          # Optional: latency alert threshold
)

# Register with your Pipecat pipeline
pipeline.register_observer(observer)

Daily.co Observer

Use ConnexityDailyObserver for Daily.co-based WebRTC calls:

from pipecat.audio.vad.vad_analyzer import VADParams
from connexity.pipecat.daily import ConnexityDailyObserver
from connexity.utils.logging_config import LogLevel

# Configure VAD parameters
vad_params = VADParams(
    confidence=0.5,
    min_volume=0.6,
    start_secs=0.2,
    stop_secs=0.8,
)

# Create and initialize the observer
observer = ConnexityDailyObserver()
await observer.initialize(
    sid=room_name,                        # Daily.co room name/ID
    agent_id="YOUR_AGENT_ID",             # Your Connexity agent ID
    api_key="YOUR_CONNEXITY_API_KEY",     # Your Connexity API key
    vad_params=vad_params,                # VAD configuration
    run_mode="production",                # "development" or "production"
    vad_analyzer="silero",                # VAD engine name
    daily_api_key="YOUR_DAILY_API_KEY",   # Daily.co API key (required)
    log_level=LogLevel.INFO,              # Optional: DEBUG, INFO, WARNING, ERROR, CRITICAL
    latency_threshold_ms=4000.0,          # Optional: latency alert threshold
)
# Note: Daily.co calls are always treated as "web" type with no phone numbers

# Register with your Pipecat pipeline
pipeline.register_observer(observer)

Tool Observer

Use @observe_tool decorator to monitor and track tool function executions:

from connexity.pipecat import observe_tool
from pipecat.services.llm_service import FunctionCallParams
from typing import Dict

@observe_tool(
    tool_name="end_call",              # Optional: explicit tool name
    include_result=True,                # Optional: capture return value (default: True)
    include_traceback=True,            # Optional: capture tracebacks on errors (default: True)
    enable_timeout=True,               # Optional: enforce execution timeout (default: True)
    timeout_seconds=10.0,              # Optional: timeout duration in seconds (default: 10.0)
)
async def end_call(params: FunctionCallParams) -> Dict[str, str]:
    # Your tool implementation
    return {"status": "ended", "sid": call_sid}

The decorator automatically tracks:

• Execution timing and duration
• Tool call IDs and arguments
• Success/failure status
• Error detection in results
• Timeout enforcement
• Callback invocation tracking

Logging Configuration

The SDK uses a centralized logging system that can be configured globally:

from connexity.utils.logging_config import set_sdk_log_level, LogLevel

# Set log level for all SDK components
set_sdk_log_level(LogLevel.DEBUG)

Available log levels: DEBUG, INFO, WARNING, ERROR, CRITICAL

Features

• Conversation Capture: Records user/assistant messages with timing
• Latency Tracking: Measures STT, LLM, TTS, and end-to-end latency
• Interruption Detection: Identifies unsuccessful user interruptions and interruption loops
• Tool Call Monitoring: Tracks function call lifecycle and issues
• Issue Reporting: Automatically reports latency peaks and errors
• System Prompt Extraction: Captures and analyzes system prompts
• Recording Integration: Retrieves call recordings from Twilio/Daily.co

CHANGELOG

v1.0.0 — 2025-12-22

New Features

• SDK Version Management Added __version__ in connexity init for library version tracking. SDK version is now sent to gateway with all API calls.

• Centralized Logging Configuration Added configurable logging system with LogLevel enum and set_sdk_log_level() function. Replaced verbose parameter with log_level for granular control (DEBUG, INFO, WARNING, ERROR, CRITICAL).

• Enhanced DocStrings Updated all files with comprehensive DocStrings describing purposes of files, classes, functions, and methods. Added default types to all variables in function signatures.

• Improved Issue Tracking Renamed internal "errors and incidents" to "issues" for consistency (exception: Pipecat ErrorFrames retained for navigation). All gateway interactions now use unified "Issues" terminology.

• STT/TTS/LLM Detailed Tracking Added detailed data capture for STT, TTS, and LLM services in CallSessionData class, including provider and model information.

Breaking Changes

• Unified run_mode Parameter Replaced env parameter with run_mode everywhere. Update all env="development" to run_mode="development".

• Observer Initialization Signatures Updated

  • ConnexityDailyObserver.initialize() now only accepts daily_api_key (not twilio_client)
  • Removed voice_engine from init signatures (auto-detected per observer type)
  • Removed phone_call_provider from init signatures (auto-set based on observer)

• Removed Deprecated Attributes

  • Removed transcriber attribute, replaced with stt_* attributes
  • Removed voice_provider attribute, replaced with tts_* attributes
  • Removed unused stream variable from client.register_call() init
