draconic21-x402-api.onrender.com/v1/gas_price

Gas Price ($0.002): current Base gas market read live from Base's own public JSON-RPC, not a hosted gas-oracle vendor -- legacy gas price (eth_gasPrice), EIP-1559 base fee (latest block), and a suggested priority/max fee (eth_maxPriorityFeePerGas + a computed 2x-base-fee heuristic), all in gwei, plus a plain-transfer cost estimate. Base mainnet only. Body {} or { chain: "base" }. Check free /v1/gas_price/availability first.
