Base URLhttps://chain.tollkit.dev/chain

POST/price$0.001Crypto token price in USD for AI agents: give a token contract address or mint (or "SOL") on Base, Ethereum or Solana, get its live USD price read on-chain from the deepest DEX pool (Uniswap v3, Orca Whirlpools), not from a price API. Returns the pool used, its depth in USD and a low-liquidity flag, so a trading agent knows how far to trust the quote.
POST/tx$0.002Transaction lookup on Base, Ethereum or Solana: give a transaction hash or signature, get its status, sender, fee and every token transfer.
POST/token$0.002Token info: give an ERC-20 or SPL token address on Base, Ethereum or Solana, get its name, symbol, decimals and total supply, plus mint and freeze authority on Solana.
POST/pretrade$0.01Check a token before trading: give a token address and trade size, get price, liquidity, rough price impact, chain warnings, your wallet's holding and recent news, in one call.
POST/portfolio$0.005Wallet portfolio value for AI agents: give a Base, Ethereum or Solana wallet address, get its native coin, USDC/USDT and any tokens you list, each with balance, USD price read on-chain from DEX pools and USD value, plus the wallet's total and warnings for thinly traded tokens. One call instead of a balance lookup and a price lookup per token.
POST/balance$0.002Wallet balance on Base, Ethereum or Solana: give an address, get its ETH or SOL, USDC, USDT and any tokens you list, read live from the chain.
POST/check$0.004Token safety check (rug check) for AI agents before buying, sending or accepting a crypto token on Base, Ethereum or Solana: give its address, get name, supply, live on-chain price and pool liquidity, plus contract controls (owner, upgradeable proxy, mint, pause, blacklist, fee setters) or Solana mint and freeze authority, with plain warnings. Facts read from the chain, not a rating.
