Axcent

The easiest way to build AI agents in Python.

Axcent is a lightweight framework designed to let you build powerful AI agents with tool calling, context caching, and multi-backend support in just a few lines of code.

Installation

pip install axcent

To use Gemini models:

pip install axcent[gemini]

Quick Start (OpenAI)

import os
from axcent import Agent

# Set your API Key
os.environ["OPENAI_API_KEY"] = "sk-..."

# Initialize Agent
agent = Agent(system_prompt="You are a helpful assistant.")

# Register a Tool
@agent.tool
def get_weather(city: str) -> str:
    """Returns weather info for a city."""
    return f"The weather in {city} is sunny!"

# Ask away!
response = agent.ask("What is the weather in Tokyo?")
print(response)

Features

• Simple Tool Registration: Just use @agent.tool.
• Automatic Context Caching: Optimizes token usage by enforcing stable prompt structures.
• Token Monitoring: Track prompt, completion, and cached tokens via agent.get_total_usage().
• Backend Agnostic:
  • OpenAI: First-class support.
  • Google Gemini: Support for all of the latest models.
  • OpenRouter: Use any model via OpenRouter API compatibility.

Multi-Backend Usage

Google Gemini

from axcent import Agent, GeminiBackend
import os

# Set API Key (or GOOGLE_API_KEY)
os.environ["GEMINI_API_KEY"] = "AIza..."

# Use Gemini Backend (uses google-genai V2 SDK)
backend = GeminiBackend(model="gemini-3-flash")
agent = Agent(system_prompt="You are a helper.", backend=backend)

OpenRouter

import os
from axcent import Agent

os.environ["OPENAI_API_KEY"] = "sk-or-..."
os.environ["OPENAI_BASE_URL"] = "https://openrouter.ai/api/v1"

agent = Agent(system_prompt="You are a helper.")
