POST a batch of up to 10 calls for ONE $0.002 payment (vs $0.005 per call at other x402 RPC gateways). Read + broadcast methods: eth_blockNumber, eth_chainId, eth_call, eth_estimateGas, eth_getBalance, eth_getTransactionCount, eth_getCode, eth_getStorageAt, eth_getTransactionByHash, eth_getTransactionReceipt, eth_getBlockByNumber, eth_getBlockByHash, eth_getLogs (<=2000 blocks), eth_gasPrice, eth_maxPriorityFeePerGas, eth_feeHistory, eth_sendRawTransaction, net_version, web3_clientVersion. Failover across 7 public Base RPCs (drpc, publicnode, mainnet.base.org, tenderly, meowrpc, blastapi, llamarpc); upstream outage = 502 = not charged. Response is a plain JSON-RPC 2.0 result so any viem/ethers client works. When to call: your agent needs a raw Base read or to broadcast a signed tx without running or renting a node.
