Chain Portfolio

by Wallet Portfolio Value in Onchain & crypto

x402 APIPassing, checked 3 h ago

Wallet portfolio value for AI agents: give a Base, Ethereum or Solana wallet address, get its native coin, USDC/USDT and any tokens you list, each with balance, USD price read on-chain from DEX pools and USD value, plus the wallet's total and warnings for thinly traded tokens. One call instead of a balance lookup and a price lookup per token.
