Paid per call: $0.01 USDC on Base, Monad, Arbitrum, Optimism, Polygon, Avalanche or Solana (eip155:8453) via x402 v2 (exact scheme, EIP-3009). Unpaid requests return HTTP 402 with machine-readable payment instructions; the buyer signs the EIP-3009 authorization off-chain and retries with the PAYMENT-SIGNATURE header. The facilitator pays the gas, so the buyer needs no ETH.
