Zero-dependency health ping for agents: returns ok, service name, ISO timestamp and epoch milliseconds. Use it to verify an x402 client end to end in under a millisecond. No upstream, no storage.

Resolve a token symbol, name or address to DEX pools on Solana, Base or Ethereum: pool, token, dex, price, liquidity, market cap and 24h volume, best liquidity first. Use it to turn a ticker into a tradeable pool address before calling pool, ohlcv, trades or holders.
