AI Router

Route your LLM calls through the AI Router with a single base URL change. Zero vendor lock-in: always run on the best model at the lowest cost for your use case.

Observability

Instrument your code with OpenTelemetry to capture traces, logs, and metrics for every LLM call, agent step, and tool use.

​
AI Router

​
Overview

CrewAI is a framework for orchestrating multi-agent teams with role-based agents, hierarchical task management, and collaborative AI workflows. By connecting CrewAI to Orq.ai’s AI Router, you get access to 300+ models for your agent crews with a single configuration change.

​
Key Benefits

Orq.ai’s AI Router enhances your CrewAI applications with:

Complete Observability

Track every agent task, tool use, and crew interaction with detailed traces

Built-in Reliability

Automatic fallbacks, retries, and load balancing for production resilience

Cost Optimization

Real-time cost tracking and spend management across all your AI operations

Multi-Provider Access

Access 300+ LLMs and 20+ providers through a single, unified integration

​
Prerequisites

Before integrating CrewAI with Orq.ai, ensure you have:
  • An Orq.ai account and API Key
  • Python 3.10 or higher
To setup your API key, see API keys & Endpoints.

​
Installation

pip install crewai

​
Configuration

Configure CrewAI to use Orq.ai’s AI Router via the LLM class with a custom base_url:
Python
from crewai import LLM
import os

llm = LLM(
    model="openai/gpt-4o",
    api_key=os.getenv("ORQ_API_KEY"),
    base_url="https://api.orq.ai/v3/router",
)
base_url: https://api.orq.ai/v3/router

​
Basic Agent Example

Python
from crewai import Agent, Task, Crew, LLM
import os

llm = LLM(
    model="openai/gpt-4o",
    api_key=os.getenv("ORQ_API_KEY"),
    base_url="https://api.orq.ai/v3/router",
)

researcher = Agent(
    role="Research Analyst",
    goal="Provide accurate and concise information on topics",
    backstory="Expert analyst with broad knowledge across many domains.",
    llm=llm,
)

task = Task(
    description="In two sentences, explain what machine learning is.",
    agent=researcher,
    expected_output="A concise two-sentence explanation of machine learning.",
)

crew = Crew(agents=[researcher], tasks=[task], tracing=False)
result = crew.kickoff()
print(result)

​
Multi-Agent Crew

Orchestrate multiple agents with specialized roles:
Python
from crewai import Agent, Task, Crew, LLM
import os

llm = LLM(
    model="openai/gpt-4o",
    api_key=os.getenv("ORQ_API_KEY"),
    base_url="https://api.orq.ai/v3/router",
)

researcher = Agent(
    role="Research Analyst",
    goal="Research topics and gather key facts",
    backstory="Expert at finding and summarizing information.",
    llm=llm,
)

writer = Agent(
    role="Content Writer",
    goal="Write clear, engaging content",
    backstory="Skilled at turning research into readable content.",
    llm=llm,
)

research_task = Task(
    description="Research the key benefits of renewable energy in 3 bullet points.",
    agent=researcher,
    expected_output="3 bullet points about renewable energy benefits.",
)

write_task = Task(
    description="Write a one-paragraph summary based on the research.",
    agent=writer,
    expected_output="A single paragraph summarizing renewable energy benefits.",
    context=[research_task],
)

crew = Crew(agents=[researcher, writer], tasks=[research_task, write_task], tracing=False)
result = crew.kickoff()
print(result)

​
Model Selection

With Orq.ai, you can use any supported model from 20+ providers:
Always prefix model IDs with openai/ when using CrewAI with the AI Router. Without it, CrewAI may route the request through a matching native provider client (notably its built-in Google client) that ignores base_url, producing misleading errors like “API key not valid”. The openai/ prefix forces the OpenAI-compatible code path, which respects base_url for every provider.
Python
from crewai import LLM
import os

# Use Claude
claude_llm = LLM(
    model="openai/anthropic/claude-sonnet-4-5-20250929",
    api_key=os.getenv("ORQ_API_KEY"),
    base_url="https://api.orq.ai/v3/router",
)

# Use Gemini
gemini_llm = LLM(
    model="openai/google/gemini-2.5-flash",
    api_key=os.getenv("ORQ_API_KEY"),
    base_url="https://api.orq.ai/v3/router",
)

# Use Groq
groq_llm = LLM(
    model="openai/groq/llama-3.3-70b-versatile",
    api_key=os.getenv("ORQ_API_KEY"),
    base_url="https://api.orq.ai/v3/router",
)

Getting Started

CrewAI enables powerful multi-agent coordination for complex AI workflows. Tracing CrewAI with Orq.ai provides comprehensive insights into agent interactions, task execution, tool usage, and crew performance to optimize your multi-agent systems.

​
Prerequisites

Before you begin, ensure you have:
  • An Orq.ai account and API Key
  • CrewAI installed in your project
  • Python 3.8+
  • OpenAI API key (or other LLM provider credentials)

​
Install Dependencies

# OpenTelemetry, crewai, openinference
pip install crewai openinference-instrumentation-crewai
pip install opentelemetry-sdk opentelemetry-exporter-otlp-proto-http

# LLM providers
pip install openai anthropic

# Optional: Advanced tools and integrations
pip install crewai-tools

​
Configure Orq.ai

Set up your environment variables to connect to Orq.ai’s OpenTelemetry collector: Unix/Linux/macOS: 
export OTEL_EXPORTER_OTLP_ENDPOINT="https://api.orq.ai/v2/otel"
export OTEL_EXPORTER_OTLP_HEADERS="Authorization=Bearer <ORQ_API_KEY>"
export OTEL_RESOURCE_ATTRIBUTES="service.name=crewai-app,service.version=1.0.0"
export OPENAI_API_KEY="<YOUR_OPENAI_API_KEY>"

Integrations Example

We’ll be using OpenInference as TracerProvider with CrewAI
from openinference.instrumentation.crewai import CrewAIInstrumentor
from openinference.instrumentation.openai import OpenAIInstrumentor
from opentelemetry import trace
from opentelemetry.exporter.otlp.proto.http.trace_exporter import OTLPSpanExporter
from opentelemetry.sdk import trace as trace_sdk
from opentelemetry.sdk.trace.export import BatchSpanProcessor
from crewai import Agent, Task, Crew

# Initialize OpenTelemetry
tracer_provider = trace_sdk.TracerProvider()
tracer_provider.add_span_processor(BatchSpanProcessor(OTLPSpanExporter(
    endpoint="https://api.orq.ai/v2/otel/v1/traces",
    headers={"Authorization": "Bearer <ORQ_API_KEY>"}
)))
trace.set_tracer_provider(tracer_provider)

# Instrument CrewAI
CrewAIInstrumentor().instrument(tracer_provider=tracer_provider)
OpenAIInstrumentor().instrument(tracer_provider=tracer_provider)

# Your CrewAI code is automatically traced
researcher = Agent(
    role='Market Research Analyst',
    goal='Gather comprehensive market data and trends',
    backstory='Expert in analyzing market dynamics and consumer behavior'
)

task = Task(
    description='Research the latest trends in AI and machine learning',
    agent=researcher,
    expected_output='Comprehensive report on AI and ML trens with key insights and recommendations'
)

crew = Crew(agents=[researcher], tasks=[task], tracing=False)
result = crew.kickoff()
