chain.tollkit.dev/chain/price

Crypto 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.
