1inch Agent Kit

Connect any LLM to 1inch DeFi protocols

The 1inch Agent Kit allows you to interact with 1inch's DeFi protocols using natural language, powered by OpenAI's GPT models. Get quotes, execute swaps, check gas prices, perform RPC calls, and monitor protocol health through simple chat interactions.

🚀 Quick Start

Installation

npm install 1inch-agent-kit

Basic Usage

import { OneInchAgentKit } from '1inch-agent-kit';

// Create agent instance
const agent = new OneInchAgentKit({
  openaiApiKey: process.env.OPENAI_API_KEY,
  oneinchApiKey: process.env.ONEINCH_API_KEY,
});

// Get a quote
const response = await agent.chat('Get me a quote for swapping 1 ETH to USDC on Ethereum');
console.log(response.content);

📋 Prerequisites

• OpenAI API Key: Get one from OpenAI Platform
• 1inch API Key: Get one from 1inch Developer Portal

🔧 Configuration

Set your API keys as environment variables:

export OPENAI_API_KEY="your-openai-api-key"
export ONEINCH_API_KEY="your-1inch-api-key"

Or pass them directly to the agent:

const agent = new OneInchAgentKit({
  openaiApiKey: 'your-openai-api-key',
  oneinchApiKey: 'your-1inch-api-key',
  openaiModel: 'gpt-4o-mini', // Optional: default model
});

🎯 Features

Supported Operations

• Get Quotes: Get the best swap routes and estimated output amounts
• Execute Swaps: Create swap transactions for execution
• Gas Price Data: Get real-time gas prices across multiple chains
• RPC Calls: Perform JSON-RPC calls against blockchain nodes
• Health Checks: Monitor API and chain health status
• Multi-Chain Support: Ethereum, Polygon, BNB Chain, Arbitrum, and more

Supported Chains

• Ethereum Mainnet (1)
• Polygon (137)
• BNB Chain (56)
• Arbitrum One (42161)
• Optimism (10)
• Avalanche C-Chain (43114)
• Base (8453)
• Polygon zkEVM (1101)

• And more...

📖 Examples

Get a Quote

const response = await agent.chat('Get me a quote for swapping 1 ETH to USDC on Ethereum with 1% slippage');
console.log(response.content);

Execute a Swap

const response = await agent.chat('Create a swap transaction for 0.1 ETH to USDC on Ethereum. My wallet is 0x1234...');
console.log(response.content);

Get Gas Prices

const response = await agent.chat('Get me the current gas prices for Ethereum mainnet');
console.log(response.content);

Perform RPC Calls

const response = await agent.chat('Get the latest block number on Ethereum mainnet');
console.log(response.content);

Check Health

const response = await agent.chat('Check the health status of the 1inch API');
console.log(response.content);

Complex Queries

const response = await agent.chat(`
  Get me a quote for swapping 1000 USDC to ETH on Polygon with 0.5% slippage.
  Use complexity level 4 and split into 5 parts for better rates.
  Also show me the current gas prices and latest block number for both chains.
`);
console.log(response.content);

🔌 Direct Function Usage

You can also use the functions directly without the LLM agent:

import { getQuote, swap, healthCheck, gasAPI, rpcAPI } from '1inch-agent-kit';

// Get quote directly
const quote = await getQuote({
  chainId: 1,
  src: "0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeEe", // ETH
  dst: "0xA0b86a33E6441b8C4C8C8C8C8C8C8C8C8C8C8C8C8", // USDC
  amount: "1000000000000000000", // 1 ETH
  slippage: 1.0
});

// Execute swap
const swapTx = await swap({
  chainId: 1,
  src: "0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeEe",
  dst: "0xA0b86a33E6441b8C4C8C8C8C8C8C8C8C8C8C8C8C8",
  amount: "1000000000000000000",
  from: "0x1234567890123456789012345678901234567890",
  slippage: 1.0
});

// Get gas prices
const gasPrices = await gasAPI({ chain: 1 });

// Perform RPC call
const blockNumber = await rpcAPI({
  chainId: 1,
  method: 'eth_blockNumber'
});

// Check health
const health = await healthCheck({ chainId: 1 });
