Function Calling Agent

Agent with function calling capabilities

Create an agent that can call custom functions, process their results, and use them to generate comprehensive responses.

Agentsfunction_calling_agent

Usage

01Add the block to your workflow and connect it to the upstream step.
02Configure any required credentials or tokens in the inputs.
03Fill in required inputs and optional parameters for the run.
04Run a test execution, inspect outputs, and iterate before deploying.
05Deploy the function_calling_agent block with monitoring enabled in production.

Function Implementations

code

Placeholder: // Define your function implementations here // These will be executed when the agent calls the functions async function get_weather(args) { const { location, unit = "celsius" } = args; // In a real implementation, you would call a weather API return { location, temperature: 22.5, unit, condition: "Sunny", humidity: 65 }; } async function calculate_mortgage(args) { const { principal, interest_rate, term_years } = args; const monthlyRate = interest_rate / 100 / 12; const payments = term_years * 12; const x = Math.pow(1 + monthlyRate, payments); const monthly = (principal * x * monthlyRate) / (x - 1); return { monthly_payment: monthly.toFixed(2), total_payment: (monthly * payments).toFixed(2), total_interest: ((monthly * payments) - principal).toFixed(2) }; }
