Base gas price and fee estimate. Live gas prices on Base (chain 8453) read from the latest block: base fee and priority fee in gwei, suggested maxFeePerGas and maxPriorityFeePerGas in wei for an EIP-1559 transaction, how full the latest block is, and the estimated execution fee in ETH for an ETH transfer and an ERC-20 transfer. Use before sending a transaction on Base or to decide whether to wait for lower fees.

Base transaction status. Look up any transaction on Base by hash: whether it succeeded, reverted or is still pending, sender and receiver, ETH value, called method id, block number and time, number of confirmations, gas used, gas price and the execution fee paid, and whether it created a contract. Use to confirm that a payment or contract call went through before acting on it.

Base balance, native coin. Native ETH balance (eth_getBalance) of any 0x wallet address on Base at the latest block, in wei and in ETH. Use to check whether a wallet can pay gas or a transfer; for ERC-20 tokens use base_token_balance, for all holdings at once use wallet_portfolio. A malformed address is rejected with 400, uncharged.

Use for timestamps and confirmation counts; for current fees use base_gas. A block that does not exist yet returns 404, uncharged.

Eth call, Base contract call. Read-only contract call on Base (eth_call) at the latest block, without a transaction or gas: send ABI-encoded calldata, or a function signature such as balanceOf(address) with args and the call is encoded and its result decoded for you. Use to read any view function that has no dedicated tool (the example reads USDC totalSupply). Calldata up to 8 KB; a call that reverts is 422 with the reason, uncharged.

Estimate gas, Base. Estimate the gas a transaction would use on Base (eth_estimateGas) and what it would cost at the current gas price, in gas units, gwei and ETH. Give to, plus value in ETH and calldata for a contract call, and the sender when the call depends on it. Use before sending a transaction or to price a batch; for the gas price alone use base_gas. A transaction that would revert is 422 with the reason, uncharged.

Use to judge whether fees are rising, pick a priority fee or time a transaction; for the current price alone use base_gas.

Base is-contract check. Check whether a 0x address on Base is a smart contract or a plain wallet: bytecode size, and whether it is an EIP-1167 minimal proxy and which implementation it points to. Use before sending funds or approving a spender; for a fuller risk verdict use check_counterparty. A malformed address is rejected with 400, uncharged.

Use to check a holder before a token-gated action or to see whether a wallet still holds a collection; for who holds one token id use base_nft_owner. Both inputs are 0x addresses; a missing contract is 404, a contract that is not ERC-721 422, both uncharged.

Counts describe directory coverage, including testnets. Each resource groups the same URL, HTTP method or MCP tool across sources. A catalog sighting records published terms. A live 402 records the endpoint’s reply to an unpaid request.
