# CurveCall

> Pay-per-call market math and token intel for AI agents via x402 (USDC on Base or Solana, or shielded ZEC, $0.001-$0.02/call, no keys or signup). Built by arbonomous.

CoinGecko tells you the price. CurveCall tells you what your buy will do: quote, slippage and rug-risk in one paid call.
