12 tools

• token

  Live on-chain facts for any ERC-20 token on Base: name, symbol, decimals, total supply, owner address and whether ownership is renounced, paused state, proxy detection (EIP-1967 and minimal proxy) with implementation and admin addresses, and bytecode heuristics for mint, pause…

• token_report

  Base token heuristic screening plus DexScreener market data, source and retrieval time. Returns owner, paused and proxy facts with limited selector checks. A mint selector does not prove callable minting; missing or unavailable evidence remains unknown. Illustrative examples are…

• wallet_audit

  Returns a heuristic high/medium/low address risk tier, named flags, ETH balance, holdings of 4 major tokens (USDC, WETH, cbBTC, DAI), and the Base EVM account nonce. Per-token risk is unknown because token contracts are not audited here. For EOAs the nonce counts outgoing…

• contract_risk

  Limited Base contract bytecode, EIP-1967 slot and zero-supply heuristics. Missing or unsupported property reads are null; RPC transport failures return 502. Ownership renunciation requires a confirmed zero owner. Empty slots do not identify uninitialized proxies. EOAs return…

• trade_insight

  Combines the Base token-report risk tier and flags, available DEX market data, and wallet-audit risk tier, flags, account nonce, and native balance. Returns the underlying indicators separately; it does not generate buy/sell recommendations or calibrated confidence, and does not…

• liquidity_pool_audit

  Base DEX pair lookup through DexScreener: verified pair identity, tokens, reported liquidity, volume, trades and pair age where available. Returns source and retrieval time; missing fields are null. No pool-security or investment-risk assessment. Missing pairs return 404…

• mev_simulator

  Estimates Base gas costs from current fees and priority-fee presets. Fixed gas units (100k simple, 250k complex, 180k liquidity) are typical assumptions, not transaction-specific estimates or quotes. Valid values: standard, high-mev (3x priority fee), low-gas (half); invalid…

• fx

  Foreign exchange rates from the European Central Bank for about 30 major currencies (USD, EUR, GBP, JPY, CHF, SEK, CAD, AUD, CNY, INR, BRL and more). Give a base currency, optionally the target currencies and an amount, and get the rates, the converted amounts and the date the…

• btc_price

  Current Bitcoin (BTC) spot price in USD, EUR, GBP, CAD, CHF, AUD and JPY, averaged across major exchanges, with the number of satoshis per US dollar and the time of the price. Use to convert between sats and fiat, to value a Bitcoin or Lightning payment, or to check the BTC…

• price_token

  USD price of any ERC-20 token on Base, Ethereum, Arbitrum or Optimism, computed from the deepest Uniswap v3 pool against USDC or WETH, read live from the chain. Returns the pool, its fee tier, the quote-token reserve and a thin-liquidity flag. Spot price, not a time average. No…

• price_tokens

  USD prices for up to 20 ERC-20 tokens on Base, Ethereum, Arbitrum or Optimism in one call, each from its deepest Uniswap v3 pool against USDC or WETH, read live from the chain, with pool, reserve and a thin-liquidity flag. Tokens without a pool are listed under unpriced instead…

• wallet_portfolio

  USD value of a wallet on Base, Ethereum, Arbitrum or Optimism: native ETH plus major tokens (USDC and WETH everywhere, the common Base tokens on Base) and up to 20 tokens you add, each priced from its deepest Uniswap v3 pool, read live from the chain. Returns holdings, total and…
