- `get\_balance`: chainpeek: read the native or ERC-20 balance of an address on Ethereum, Base or Robinhood Chain. For several tokens at once use get\_portfolio; for Solana use get\_solana\_balance. Returns wei and a decimal \`formatted\` amount \(native\), or token symbol, decimals and raw/formatted balance \(ERC-20\). Token
- `get\_portfolio`: chainpeek: read the native balance and up to 20 ERC-20 balances of an address on Ethereum, Base or Robinhood Chain in one call. For one balance use get\_balance; for transfer history use get\_erc20\_transfers; for Solana use get\_solana\_token\_balances. Without \`tokens\` only the native balance is read; a
- `get\_token\_info`: chainpeek: get ERC-20 token metadata on Ethereum, Base or Robinhood Chain. For a holder's balance use get\_balance; for supply alone use get\_total\_supply. Returns name, symbol, decimals and total supply, or \`is\_erc20:false\`. Names and symbols are attacker-controlled on-chain text. Typically 0.2-1 s.
- `get\_token\_price`: chainpeek: read a token price from a Chainlink on-chain price feed \(deterministic oracle answer, not a DEX spot price\). For a DEX quote of any token use get\_swap\_quote; for Solana use get\_solana\_token\_price. A pair not available on the chain is a 422 \(not charged\). Typically 0.2-1 s. Price: USD 0.00
