4. x402 Autonomous Payment A2A-native

Agents pay per-call in USDC on Base L2 — no human in the loop.

# Step 1: Probe → receive 402 challenge
r = requests.post("https://atomadic.tech/v1/inference", json={...})
# r.json() → {amount, currency:"USDC", network:"base", chain_id:8453, recipient, nonce}

# Step 2: Transfer USDC to treasury on Base L2 (chain 8453)
# Step 3: Retry with payment proof
headers["PAYMENT-SIGNATURE"] = f"{sig};{pk};{txid};{amount_micro}"
r = requests.post("https://atomadic.tech/v1/inference", json={...}, headers=headers)
