• GET/x402_chain_reads_v1/eth_get_transaction_receipt$0.005Returns the transaction receipt for a given transaction hash on Base. Takes one query parameter: hash, the 0x-prefixed transaction hash. Base RPC read of an address, block or transaction.
• GET/x402_chain_reads_v1/ens_resolve$0.005ENS resolution on Ethereum mainnet. Pass name (an ASCII .eth name) to get its resolved address, or address (0x + 40 hex) to get its primary ENS name, reverse-resolved and verified forward.
• GET/x402_chain_reads_v1/base_eth_gettransactionreceipt$0.003Returns the Base transaction receipt for a transaction hash: status, logs bloom, gas used, effective gas price, and contract address when one was created. Takes hash (0x + 64 hex). Base RPC read of an address, block or transaction.
