Quick Start

OpenAI

import os
from openai import OpenAI
from telnyx_agent_toolkit import TelnyxAgentToolkit

toolkit = TelnyxAgentToolkit(
    api_key=os.environ["TELNYX_API_KEY"],
    configuration={
        "actions": {
            "messaging": {"send_sms": True},
            "numbers": {"list": True, "search": True},
            "account": {"get_balance": True},
        }
    },
)

client = OpenAI()
tools = toolkit.get_openai_tools()
executor = toolkit.get_openai_tool_executor()

response = client.chat.completions.create(
    model="gpt-4o",
    messages=[{"role": "user", "content": "What's my Telnyx balance?"}],
    tools=tools,
)

# Execute tool calls
for tool_call in response.choices[0].message.tool_calls:
    result = executor.execute(tool_call)
    print(result)

LangChain

from telnyx_agent_toolkit import TelnyxAgentToolkit

toolkit = TelnyxAgentToolkit(api_key="KEY...")
tools = toolkit.get_langchain_tools()

# Use with any LangChain agent
from langchain_openai import ChatOpenAI
llm = ChatOpenAI(model="gpt-4o")
llm_with_tools = llm.bind_tools(tools)

CrewAI

from crewai import Agent
from telnyx_agent_toolkit import TelnyxAgentToolkit

toolkit = TelnyxAgentToolkit(api_key="KEY...")
tools = toolkit.get_crewai_tools()

agent = Agent(
    role="Telecom Specialist",
    goal="Help manage phone numbers and messaging",
    tools=tools,
)

Configuration

Control which tools are available to the agent:

toolkit = TelnyxAgentToolkit(
    api_key="KEY...",
    configuration={
        "actions": {
            # Messaging
            "messaging": {
                "send_sms": True,            # Send SMS/MMS
                "list_messaging_profiles": True,
                "create_messaging_profile": True,
            },
            # Phone Numbers
            "numbers": {
                "list": True,    # List account numbers
                "search": True,  # Search available numbers
                "buy": True,     # Purchase numbers (charges account)
            },
            # Account
            "account": {
                "get_balance": True,
            },
            # Voice
            "voice": {
                "make_call": True,
                "list_connections": True,
            },
            # AI
            "ai": {
                "chat": True,              # Chat completions
                "embed": True,             # Embeddings
                "list_ai_assistants": True,
                "create_ai_assistant": True,
            },
            # Fax
            "fax": {
                "send_fax": True,
            },
            # Lookup
            "lookup": {
                "lookup_number": True,     # Carrier/CNAM lookup
            },
            # IoT
            "iot": {
                "list_sim_cards": True,
            },
            # Verification
            "verify": {
                "verify_phone": True,      # Send verification code
                "verify_code": True,       # Check verification code
            },
        }
    },
)

No configuration = all tools enabled. Use configuration to restrict which tools the agent can access.

Async Support

All tools support async execution natively:

# Async execution
result = await executor.execute_async(tool_call)

# Direct tool execution
result = await toolkit.core.run_tool_async("get_balance", {})

API Client

Access the underlying HTTP client directly:

# Async
data = await toolkit.api_client.get_async("/phone_numbers")

# Sync
data = toolkit.api_client.get("/phone_numbers")

Requirements

• Python 3.11+
• Telnyx API key
