Installation

Requirements

• Python 3.11+
• An API key for your chosen LLM provider

Core install

pip install agentix-agent-sdk

The core package bundles all supported LLM provider SDKs along with pydantic, httpx, tiktoken, and MCP support. No extra install step is needed to use any provider.

Optional extras

Extra	Installs	Use case
gateway	aiohttp + adapter deps	Messaging gateway — HTTP webhooks, Slack, WhatsApp, Email
gateway-slack	slack-sdk	Slack adapter only (lighter than full gateway)
gateway-whatsapp	gateway-core	WhatsApp Business API adapter
gateway-email	aiosmtplib	Email adapter (SMTP/IMAP)
dev	pytest, mypy, ruff, fakeredis	Development and testing tools
all	redis + all gateway adapters + dev	Everything

pip install agentix-agent-sdk[gateway]         # All messaging gateway adapters
pip install agentix-agent-sdk[all]             # Everything

API key

Pass your LLM provider API key via the AGENTIX_API_KEY environment variable:

export AGENTIX_API_KEY=your-api-key-here

Or supply it inline via llm_options:

options = AgentixAgentOptions(
    provider="anthropic",
    llm_options={"api_key": "your-api-key-here"},
)

Agentix automatically redacts api_key from logs and __repr__ to prevent accidental leakage.

OpenAI-compatible endpoints

For any OpenAI-compatible endpoint (Cerebras, Ollama, vLLM, LiteLLM, etc.) use provider="openai_compatible" and set base_url:

options = AgentixAgentOptions(
    provider="openai_compatible",
    model="your-model-name",
    llm_options={
        "base_url": "http://localhost:11434/v1",  # e.g. Ollama
        "api_key": "ollama",
    },
)

Or via environment variables:

export AGENTIX_PROVIDER=openai_compatible
export AGENTIX_BASE_URL=http://localhost:11434/v1
export AGENTIX_MODEL=llama3.2

Web search keys (optional)

WebSearch auto-detects which backend to use based on available keys:

export TAVILY_API_KEY=tvly-...     # recommended
export BRAVE_API_KEY=BSA...
export SERPAPI_API_KEY=...
# (no key) → falls back to DuckDuckGo

Verify installation

import agentix
print(agentix.__version__)
