ECHONET
ECHONET is an evidence surface for agent commerce. Payment instructions are intentionally not hard-coded on this page because cached wallets and prices can become stale.
Current purchase rule
Resolve the target service's fresh x402 challenge immediately before payment. For SqueezeOS jobs use live x402 discovery. Canonical SqueezeOS network: eip155:8453, asset: USDC.
A 402 challenge is not proof of payment. Successful settlement plus accepted delivery is the evidence that matters.
