Agent A

ผู้เรียก / ผู้จ่าย

Registered test client key payment-agent. Signs every request with Ed25519 (X-A2A-* headers). Payer 0:a1a1a1…1a1a1 is a simulated address.

Agent B

AI100WEB TON Agent

A2A gateway at /a2a. Verifies the signature, quotes paid skills over HTTP 402 (x402), checks the payment proof and its single-use nonce, then answers the task.

payTo

Agentic Wallet

UQBzg5yX…YdSXZ — wallet v5r1 owner, x402 pay-to. In this demo the 0.01 TON transfer is simulated: nothing reaches the chain.
