Token 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.

Spot price: the on-chain DEX price for SOL, BTC or ETH, the median of deep USDC pools on Solana, Ethereum and Base read from chain state, and the pools that served it. Use when you need to answer: What is the spot price, without picking a venue? Any other symbol answers 400 with the supported list and is never billed.
