Machine-payable JSON-RPC across an 82-chain relay (ethereum, base, solana, arbitrum, polygon, bsc and the full published chain list). POST a single JSON-RPC call object or a <=10-item batch to /api/v1/x402/rpc/{chain} and get the upstream result verbatim; $0.002/call in USDC on Solana, Base, Polygon, Arbitrum or Avalanche. Unchargeable upstream failures are never billed.
