OmniDimension Python SDK

Build and ship AI voice agents from a single prompt.

OmniDimension lets you build, test, and deploy reliable voice AI assistants by simply describing them in plain text. The platform offers rigorous simulation testing and real-time observability, making it easy to debug and monitor agents in production.

👉 Try the Web UI — You can also build and test voice agents visually using our no-code interface.

🚀 Features

• Prompt-based creation: Define voice agents with natural language.
• Drag-and-drop editor: Chat or visually edit flows, voices, models, and more.
• Prebuilt templates: Use plug-and-play agent templates for common use cases.
• Testing & monitoring: Simulate edge cases and debug live calls.
• Knowledge Base support: Upload and attach documents (PDFs) for factual grounding.
• Integrations: Connect to external APIs, CRMs, or tools like Cal.com.
• Phone agents: Assign numbers and initiate real voice calls via the SDK.
• Bulk Call: Send multiple voice calls AI to multiple numbers simultaneously.

📦 Installation

Basic SDK

pip install omnidimension

Requires Python 3.9+

🔐 Authentication

First, obtain your API key from the OmniDimension dashboard. Store it in your environment variables:

Linux/macOS

export OMNIDIM_API_KEY="your_api_key_here"

Windows (CMD)

set OMNIDIM_API_KEY=your_api_key_here

In Python

import os
from omnidimension import Client

api_key = os.environ.get("OMNIDIM_API_KEY")
client = Client(api_key)

✨ SDK Usage

from omnidimension import Client

# Initialize the client with your API key
client = Client(api_key="your_api_key")

# List agents
agents = client.agent.list()
print(agents)

🛰️ MCP server

The OmniDimension MCP server lives in its own repositories, not in this SDK. Pick whichever fits your client.

Hosted (no install)

Point any MCP client at the hosted server. It speaks the standard OAuth flow, so clients discover the rest automatically:

https://mcp.omnidim.io/mcp

For Claude Code:

claude mcp add --transport http omnidim https://mcp.omnidim.io/mcp --scope user

Source: Omnidim/omnidim-mcp-cloud

Local (stdio)

For clients that launch a local server (Claude Desktop, Cursor, Windsurf), use the npm package @omnidim-ai/mcp-server. Save this as your MCP client config:

{
  "mcpServers": {
    "omnidim": {
      "command": "npx",
      "args": ["-y", "@omnidim-ai/mcp-server"],
      "env": {
        "OMNIDIM_API_KEY": "<your_omnidim_api_key>"
      }
    }
  }
}

Source: Omnidim/omnidim-mcp-server

📡 Providers API

The Providers API allows you to discover and explore all available AI providers for LLMs, voices, STT, and TTS services.

Quick Examples

# Get all LLM providers
llms = client.providers.list_llms()
print(f"[SUCCESS] Found {llms['total']} LLM providers")

# List voices with pagination
voices = client.providers.list_voices(page=1, page_size=50)
print(f"[SUCCESS] Found {voices['total']} voices")

![INFO] Complete Providers Documentation

📚 Knowledge Base

files = client.knowledge_base.list()
print(files)

file_ids = [123]
agent_id = 456
response = client.knowledge_base.attach(file_ids, agent_id)
print(response)

🔌 Integrations

response = client.integrations.create_custom_api_integration(
    name="WeatherAPI",
    url="https://api.example.com/weather",
    method="GET"
)
print(response)

client.integrations.add_integration_to_agent(agent_id=123, integration_id=789)

☎️ Phone Number Management

numbers = client.phone_number.list(page=1, page_size=10)
print(numbers)

client.phone_number.attach(phone_number_id=321, agent_id=123)

# Search for numbers available to purchase in a region
# carrier is region-specific; every region currently requires one. Omitting it
# (or passing an unknown value) gets a 409/404 back listing the valid carriers.
available = client.phone_number.search(region="US", pattern="415", page=1, limit=20, carrier="carrier-us")
print(available)

# Purchase one of the numbers found above
purchase = client.phone_number.purchase(
    region="US",
    phone_number="+14155550123",
    carrier="carrier-us",
    idempotency_key="order-2024-12-01-001"  # safe to retry with the same key
)
print(purchase)

# Release a number you no longer need
client.phone_number.release(phone_number="+14155550123")

Reseller accounts can pass user_id to list, search, purchase, and release to act on a specific child client's account instead of their own.

🤝 Reseller Management

Reseller-only methods for managing child organizations, users, credits, and KYC.

# List child organizations
orgs = client.reseller.list_organizations()

# Create a new child user
new_user = client.reseller.add_user(
    name="Jane Doe",
    email="jane@example.com",
    phone="+14155550123",
    password="a-strong-password",
    welcome_minutes_to_credit=100,
    cost_per_min=0.05
)

# Control which dashboard menus a child user can see
client.reseller.set_access_control(
    user_id=456,
    dashboard_menu_access={"billing": True, "agents": True, "integrations": False}
)

# Set or clear a child account's expiry date
client.reseller.set_expiry(user_id=456, expiry_date="2025-12-31")
client.reseller.set_expiry(user_id=456)  # clears the expiry

# Set a child organization's concurrent call limit (absolute value, not a delta)
client.reseller.set_concurrency(child_organization_id=789, new_limit=10)

# Calculate and transfer credits
cost = client.reseller.calculate_credits(minutes=500, cost_per_min=0.05)
client.reseller.transfer_credits(to_organization_id=789, minutes=500, cost_per_min=0.05)

# Revert a previous transfer (uses the original rate, no cost_per_min to pass)
client.reseller.revert_credits(from_organization_id=789, minutes=500)

# Credit transfer/revert history
logs = client.reseller.credit_logs(page=1, page_size=30)

# KYC: check status, then walk next_step until it reports "completed"
# carrier decides both the requirements and the step flow; every region
# currently requires one, and step names are only knowable from this call.
status = client.reseller.kyc_status(user_id=456)
requirements = client.reseller.kyc_requirements(region="IN", carrier="carrier-1")
client.reseller.submit_kyc_step(
    step="register", user_id=456, region="IN", carrier="carrier-1", full_name="Jane Doe")
