CrewAI Integration

CrewAI is a framework for building multi-agent AI systems. It allows you to define specialized AI agents with specific roles, tools, and goals that collaborate to accomplish complex tasks.

CrewAI supports custom LLM providers through its configuration, including OpenAI-compatible endpoints.

Prerequisites

An LLM API account with an API key
CrewAI installed or accessible

Setup

Get Your LLM API Key

Log in to your LLM API dashboard
Click Create Key to Start
Copy your new API key immediately — it will only be shown once
Store the key securely (e.g., in a password manager or .env file)

LLM API is an OpenAI-compatible gateway that gives you access to dozens of AI models through a single API key and endpoint.

Configure LLM API in CrewAI

Set environment variables:

export OPENAI_API_KEY="your-llm-api-key-here"
export OPENAI_API_BASE="https://api.llmapi.ai/v1"

Or configure inline in your crew definition:

from crewai import Agent, LLM
llm = LLM(
model="openai/gpt-4o",
api_key="your-llm-api-key-here",
base_url="https://api.llmapi.ai/v1"
)
agent = Agent(
role="Researcher",
goal="Find information",
llm=llm
)

All agents in the crew will use LLM API.

Test the Integration

Verify that CrewAI can successfully communicate with LLM API by sending a test request. All requests will now be routed through LLM API.

Each agent in CrewAI can use a different model. LLM API lets you mix models with a single key.

Benefits of Using LLM API with CrewAI

Multi-Provider Access: Use models from OpenAI, Anthropic, Google, and more through a single API
Cost Control: Track and limit your AI spending with detailed usage analytics
Unified Billing: One account for all providers instead of managing multiple API keys
Caching: Reduce costs with response caching for repeated requests
