Functions

Function calling for blockchain interactions

Learn how we use function calling to interact with protocols & user data. Understand available functions & how natural language queries are translated into actions.

How Function Calling Works

Natural Language Input

User provides natural language query like "Trade 100 USDC for ETH"

Function Selection

AI analyzes the query & selects appropriate functions to execute the request.

Execution & Confirmation

Functions execute & return results. User confirms before any on-chain transactions.

Available Functions

Portfolio Functions

get_portfolio_summary(address: string)
// Returns: total value, token balances, allocation

getUserProfile(userId: string)
// Returns: user preferences, settings, saved addresses

getTokenPrice(tokenAddress: string, chainId: number)
// Returns: current price, 24h change, market data

Trade Functions

getEnsoRoute(params: SwapParams)
// Returns: optimal trade route, expected output, price impact

executeEnsoRoute(route: Route, wallet: Wallet)
// Executes: trade transaction, returns receipt

getLifiRoute(params: BridgeParams)
// Returns: bridge route, estimated time, fees

DeFi Functions

getAavePosition(address: string, chainId: number)
// Returns: supplied assets, borrowed assets, health factor

supplyToAave(params: SupplyParams)
// Executes: supply assets to Aave

borrowFromAave(params: BorrowParams)
// Executes: borrow assets against collateral

Example Flow

example-flow.ts
// User query: "Trade 100 USDC for ETH on Base"

// 1. AI calls getEnsoRoute
const route = await getEnsoRoute({
  fromToken: 'USDC',
  toToken: 'ETH',
  amount: '100',
  chainId: 8453, // Base
})

// 2. AI presents results to user
console.log(`Expected output: ${route.amountOut} ETH`)
console.log(`Price impact: ${route.priceImpact}%`)

// 3. User confirms
if (userConfirms) {
  // 4. AI calls executeEnsoRoute
  const receipt = await executeEnsoRoute({
    route,
    wallet: userWallet,
  })
  
  console.log('Transaction confirmed:', receipt.hash)
}
