2026-11-02token_checkchangeddescription
before
Check a token before buying, sending or accepting it, on Base, Ethereum or Solana: what it is, its USD price and liquidity, and plain warnings read from the chain (no pool, thin liquidity; on Base and Ethereum the contract's owner and whether it is upgradeable or can mint, pause, blacklist or set fees; on Solana an active mint or freeze authority). $0.004 USDC per call over x402. Failed calls cost nothing. Call without `payment` to get a quote. The first 3 calls a day through this tool server are free (no wallet needed). When to use: Before buying, accepting or sending an unfamiliar token. Use instead: pretrade_check when you're about to trade a specific amount (adds price impact, your holding and news); token_info for the basics only. Parameters: token: ERC-20 contract or SPL mint. chain: base (default), ethereum or solana. Returns: what the token is, price and liquidity, and plain-language warnings (owner, upgradeable, can mint, pause, blacklist or set fees; Solana mint or freeze authority).
