base_demo

Free. Returns a complete, live contract audit of Base USDC — the same output shape as the paid audit tool, with the address fixed. Call this first to see what the paid tools return before spending any…

base_address_check

Pre-flight check on a Base mainnet address before you pay it: contract vs EOA, ETH and USDC balances, outbound tx count, and warnings about whether funds sent there can actually be moved. Costs $0.002…

base_tx_check

Confirm a Base mainnet transaction: success or reverted, block, confirmations and finality, gas used, and every ERC-20 transfer it moved with USDC amounts decoded. Costs $0.002 per call, paid in USDC …

base_token

ERC-20 token metadata on Base mainnet: name, symbol, decimals and total supply, read straight from the contract. Costs $0.001 per call, paid in USDC over x402 on Base. Calling this tool returns the pa…

base_gas

Live Base mainnet gas oracle: current gas price, base fee, recent base fee trend, priority fee percentiles, and the estimated cost of a plain ERC-20 transfer in ETH. Costs $0.001 per call, paid in USD…

base_price

ETH/USD and BTC/USD read live from Chainlink's on-chain price feeds on Base, with the feed's own description, decimals, update timestamp, age in seconds and a staleness flag. Costs $0.001 per call, pa…

base_contract_type

Identify what a Base contract actually is: ERC-20, ERC-721 or ERC-1155 via ERC-165, plus proxy detection across EIP-1967, EIP-1822 and the legacy ZeppelinOS slot with the current implementation addres…

base_allowance

ERC-20 allowance on Base: how much a spender may pull from an owner, whether it is an unlimited approval, the owner balance, and how much is actually spendable right now. Defaults to USDC. Costs $0.00…

base_token_price

USD price for ANY token on Base, not just the two assets Chainlink covers. Discovers every Uniswap V3 pool against WETH and USDC across all four fee tiers, reads sqrtPriceX96 and does the Q96 fixed-po…

base_simulate_transfer

Will this token payment actually go through, and if not exactly why. Simulates the transfer without spending gas, decodes the real revert reason (Error(string), Panic codes translated to English, or a…

base_contract_audit

What an UNVERIFIED Base contract can actually do — the case where block explorers show you nothing. Disassembles the deployed bytecode with a PUSH-aware opcode walk (a naive byte scan reports SELFDEST…

base_portfolio

ETH and USDC balances for up to 20 Base addresses in a single call, with per-address funded flags and totals. One request instead of forty RPC round trips. Costs $0.003 per call, paid in USDC over x40…
