What we built

Every arrow is a real
USDC transaction

Not a simulation. Real USDC flowing between autonomous agents on Stellar testnet — fully verifiable on-chain.

🤖

Agent-to-agent payments

Orchestrator hires Research Agent, Research Agent hires Writing Agent. A full payment chain with zero human involvement.

Core feature

⚡

x402 on Stellar

HTTP 402 → pay USDC → retry with cryptographic proof. Every API call is a real micropayment. The full x402 protocol, live.

How it works

The x402 payment flow

User submits a query

Type any research question into the dashboard. The orchestrator agent receives it and decides which specialist agents to hire.

Server returns HTTP 402

When an agent requests a service, the server responds with 402 Payment Required + Stellar payment instructions.

price: 0.005 USDC

Agent pays on Stellar

The calling agent automatically submits a USDC payment on Stellar. No human approval. Settles in under 5 seconds.

Retry with proof

Agent retries with the tx hash as X-Payment header. Server verifies on-chain, then serves the response.

Report delivered

The Writing Agent polishes gathered data into a final report, which appears in the dashboard for the user to read.

x402.js — payment flow

// Agent requests a paid service
let res = await fetch(url, { headers });

// Server: 402 + payment instructions
if (res.status === 402) {
  const { payment } = await res.json();

  // Pay USDC on Stellar — no human
  const { proof } = await stellarPay(
    keypair,
    payment.destination,
    parseFloat(payment.price)
  );

  // Retry with cryptographic proof
  res = await fetch(url, {
    headers: {
      'x-payment': proof
    }
  });
}
// ✓ Service responds with data
return res.json();
        

Why Stellar

Built for micropayments

x402 is synchronous HTTP — the agent waits for payment confirmation before retrying. Stellar is the only network fast and cheap enough to make this viable.
