How this service works
Portfolio of any wallet in one call with total USD: for an EVM address the native coin and major tokens on Base, Ethereum, BSC, Arbitrum, Polygon, Avalanche and Optimism at once; for a Solana address SOL and every SPL token with a market price; Bitcoin and Tron addresses too. Per asset amount and USD, totals per chain. For agents that check a counterparty, a treasury or their own funds before acting.
Output
A structured breakdown of all assets held by the wallet: per-asset token symbol, amount, and USD value; totals per chain; and an overall total USD portfolio value. For EVM addresses covers native coins and major tokens across Base, Ethereum, BSC, Arbitrum, Polygon, Avalanche, and Optimism. For Solana covers SOL and all priced SPL tokens. Also supports Bitcoin and Tron addresses.
Example use cases
Treasury check before DeFi action
“Before we proceed with the on-chain transaction, check the treasury wallet 0xAbC123...def456 and tell me the total USD value and what tokens it holds across Ethereum, Base, and Arbitrum.”
Counterparty due diligence
“I'm about to do a deal with this Solana address 7xKp...3mNq — can you pull up their full portfolio, all SPL tokens and SOL balance with USD values, so I can see what they're working with?”
Personal crypto net worth check
“What's my total crypto net worth right now? My wallet is 0x9fE46736679d2D9a65F0992F2272dE9f3c7fa6e0 — give me everything across all chains, skip anything worth less than $5.”

Endpoint
POSThttps://agentsvc.io/api/v1/proxy/wallet-portfolio?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a complete, cross-chain snapshot of any wallet's holdings in a single call. It's ideal for agents that need to check counterparty funds, audit treasury wallets, or verify available balances before taking on-chain action. Prefer it over chain-specific RPC calls when you need multi-chain aggregation with live USD pricing in one round trip.
Side effects
- Invalid or malformed wallet address returns an error — ensure address format matches the chain (0x... for EVM, base58 for Solana/Bitcoin/Tron)
- Wallet with no assets or all assets below min_usd threshold returns empty portfolio
- Price data unavailable for obscure tokens — those assets may be omitted or shown without USD value
- Network timeout or upstream price feed outage may result in partial data or service error
- Tron or Bitcoin address with no transaction history may return zero balances
