Xpander SDK

Xpander Open Source SDK empowers developers to build intelligent and reliable AI Agents capable of managing complex, multi-step tasks across diverse systems and platforms. The SDK simplifies challenges like function calling, schema definition, graph enforcement, and prompt group management.

With support for leading LLM providers such as OpenAI, Amazon Bedrock, and NVIDIA NIM, the Xpander SDK seamlessly integrates into your existing systems.

📦 Installation

Choose your preferred package manager:

npm

npm install xpander-sdk

pip

pip install xpander-sdk

🚀 Getting Started

Prerequisites

1. Visit app.xpander.ai
2. Retrieve your Agent Key from the Agent Settings page
3. Install the SDK and make sure you have Node.js installed (required as the SDK runs as a Node.js app under the hood)

Quick Start Examples

TypeScript

import { XpanderClient } from 'xpander-sdk';
import * as dotenv from 'dotenv';

dotenv.config();

const xpanderAPIKey = process.env.XPANDER_API_KEY || '';
const xpanderAgentID = process.env.XPANDER_AGENT_ID || '';

const xpanderClient = new XpanderClient({ apiKey: xpanderAPIKey });
const agent = await xpanderClient.agents.get(xpanderAgentID);

// Get available tools for the agent
const tools = await agent.getTools();

// This is a placeholder for AI to analyze the tools and decide which to invoke
// You would typically send these tools to your AI provider (e.g., OpenAI, Anthropic)
// The AI will return a structured response indicating which tools to call
const llmResponse = await yourAIProvider.chat.completions.create({
  messages: [userMessage],
  tools: tools // The tools are formatted for the AI to understand
  // ... other AI configuration
});

// Parse LLM response automatically into tool calls
const toolsToRun = XpanderClient.extractToolCalls(llmResponse);

// Execute multiple tool calls at once
const results = await agent.runTools(toolsToRun);

JavaScript

const { XpanderClient } = require('xpander-sdk');
require('dotenv').config();

const xpanderAPIKey = process.env.XPANDER_API_KEY || '';
const xpanderAgentID = process.env.XPANDER_AGENT_ID || '';

const xpanderClient = new XpanderClient({ apiKey: xpanderAPIKey });
const agent = await xpanderClient.agents.get(xpanderAgentID);

// Get available tools for the agent
const tools = await agent.getTools();

// This is a placeholder for AI to analyze the tools and decide which to invoke
// You would typically send these tools to your AI provider (e.g., OpenAI, Anthropic)
// The AI will return a structured response indicating which tools to call
const llmResponse = await yourAIProvider.chat.completions.create({
  messages: [userMessage],
  tools: tools // The tools are formatted for the AI to understand
  // ... other AI configuration
});

// Parse LLM response automatically into tool calls
const toolsToRun = XpanderClient.extractToolCalls(llmResponse);

// Execute multiple tool calls at once
const results = await agent.runTools(toolsToRun);

Python

from xpander_sdk import XpanderClient
from dotenv import load_dotenv
import os

load_dotenv()

xpanderAPIKey = os.environ.get("XPANDER_API_KEY", "")
xpanderAgentID = os.environ.get("XPANDER_AGENT_ID", "")

xpander_client = XpanderClient(api_key=xpanderAPIKey)
agent = xpander_client.agents.get(agent_id=xpanderAgentID)

# Get available tools for the agent
tools = agent.get_tools()

# This is a placeholder for AI to analyze the tools and decide which to invoke
# You would typically send these tools to your AI provider (e.g., OpenAI, Anthropic)
# The AI will return a structured response indicating which tools to call
llm_response = your_ai_provider.chat.completions.create(
    messages=[user_message],
    tools=tools  # The tools are formatted for the AI to understand
    # ... other AI configuration
)

# Parse LLM response automatically into tool calls
tools_to_run = XpanderClient.extract_tool_calls(llm_response=llm_response.model_dump())

# Execute multiple tool calls at once
results = agent.run_tools(tools_to_run)

C#

using Xpander.Sdk;
using DotEnv.Net;

new DotEnvLoader().Load();

var xpanderAPIKey = Environment.GetEnvironmentVariable("XPANDER_API_KEY") ?? "";
var xpanderAgentID = Environment.GetEnvironmentVariable("XPANDER_AGENT_ID") ?? "";

var xpanderClient = new XpanderClient(xpanderAPIKey);
var agent = await xpanderClient.Agents.GetAsync(xpanderAgentID);

// Get available tools for the agent
var tools = await agent.GetToolsAsync();

// This is a placeholder for AI to analyze the tools and decide which to invoke
// You would typically send these tools to your AI provider (e.g., OpenAI, Anthropic)
// The AI will return a structured response indicating which tools to call
var llmResponse = await yourAIProvider.chat.completions.create({
  messages: [userMessage],
  tools: tools // The tools are formatted for the AI to understand
  // ... other AI configuration
});

// Parse LLM response automatically into tool calls
var toolsToRun = XpanderClient.ExtractToolCalls(llmResponse);

// Execute multiple tool calls at once
var results = await agent.RunToolsAsync(toolsToRun);
