Composable Agentic Workflows

🎬 Demo Scenarios

1. Autonomous Payment Workflow

// Agent discovers service
var service = await agent.DiscoverServiceAsync("data-api");

// Negotiates price
var price = await agent.NegotiateAsync(service);

// Plans payment
var plan = await agent.CreatePaymentPlanAsync(price);

// Executes via MNEE
var txHash = await agent.PayWithMNEEAsync(plan);

// Verifies on blockchain
await agent.VerifyTransactionAsync(txHash);

// Learns from outcome
await agent.ReflectAndLearnAsync(result);

2. Multi-Agent Collaboration

var negotiator = AgentFactory.CreateNegotiator();
var planner = AgentFactory.CreatePlanner();
var executor = AgentFactory.CreateExecutor();

var orchestrator = new MultiAgentOrchestrator(
    negotiator, planner, executor
);

var result = await orchestrator.ExecutePaymentWorkflowAsync(goal);
