What it can do
| Tool | What it says it does |
|---|---|
base_address | Base (chain 8453) address snapshot: EOA vs contract vs EIP-7702, ETH balance, nonce, code size and native USDC balance, at the latest block. Costs $0.002 USDC on Base via x402. |
base_catalog | Lists every BaseLens tool with price, inputs and the equivalent x402 HTTP URL. |
base_contract | Contract check on Base: is it a contract, code size, owner(), proxy implementation, and whether the source (and implementation) is verified on Sourcify, plus plain-language notes. Not an audit. Costs $0.003 USDC on Base via x402. |
base_erc20_balance | ERC-20 balance of any address for any token on Base, with symbol and decimals already applied (raw and human-readable). Costs $0.002 USDC on Base via x402. |
base_free_gas_sample | Free sample: latest Base block number and base fee (gwei). Use it to test the connection. |
base_gas | Current Base gas: base fee, gas price, suggested EIP-1559 max fee and priority fee (gwei), block fullness, and cost of a plain ETH transfer. Costs $0.001 USDC on Base via x402. |
base_name | Resolve a Basename (name.base.eth) or ENS name to its Base/Ethereum address, or reverse-resolve an address to its primary ENS/Basename. Includes avatar record. Costs $0.001 USDC on Base via x402. |
base_price | On-chain USDC price of any Base ERC-20: executable Uniswap v3 quote for 1 whole token (direct USDC pool or via WETH, best fee tier). No third-party price API. Costs $0.003 USDC on Base via x402. |
base_token | Token facts on Base: name, symbol, decimals, total supply, contract code size, owner() and EIP-1967 proxy implementation, plus plain-language notes (upgradeable? owner renounced?). Read-only facts, not advice. Costs $0.003 USDC on Base via x402. |
base_transfers | Recent ERC-20 transfers in and out of an address on Base for up to 5 tokens (default USDC), newest first, over the last ~10k blocks (max 30k). Check incoming payments or wallet activity. Costs $0.004 USDC on Base via x402. |
base_tx | Human-readable summary of a Base transaction: status, block time, from/to, value, total fee (incl. L1 fee), and decoded ERC-20 Transfer events with token symbols and amounts. Handy to verify a payment landed. Costs $0.003 USDC on Base via x402. |
In its maker's words
Base on-chain data for agents: balances, prices, transfers, Basenames, contracts. x402 pay-per-call.
