How this service works
558 pay-per-call data APIs for AI agents: Solana and EVM on-chain data, tokenized stocks, DeFi, Hyperliquid, economy and official statistics, FX, validation, web and developer tools. Pay in USDC via x402.
Output
Returns a list of token balances where each entry includes the asset symbol, the token amount held, and an approximate USD value. Also returns the total portfolio value in USD across all detected tokens.
Example use cases
DeFi portfolio snapshot
“Can you pull up all the token balances and their USD values for my wallet 0xAbC123...456 on the Ethereum network? I want to see my full holdings.”
Base network balance check
“Check the wallet balance for address 0x5aAeb6053F3E94C9b9A09f33669435E7Ef1BeAf on the Base network and tell me what tokens it holds and what they're worth in USD.”
ERC-20 token holding lookup
“Look up how much USDC the wallet 0xdAC17F958D2ee523a2206206994597C13D831ec7 holds on Ethereum and what that's worth right now.”
Technical details
Endpoint
POSThttps://api.vextorium.com/v1/wallet-balances?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to quickly look up all token balances and their approximate USD values for a single EVM wallet address on Base or Ethereum. Prefer this over block explorer APIs when you want a structured, aggregated portfolio view with USD conversion in a single call. Best suited for DeFi agents, portfolio trackers, and any workflow that needs a fast on-chain balance snapshot.
Side effects
- Invalid or malformed wallet address returns an error or empty balances
- Network not specified defaults may vary; unsupported networks return an error
- Unrecognized or low-liquidity ERC-20 token contract may return null USD value
- Address with zero activity returns empty balances array
- Rate limiting or payment failure returns HTTP 402 or 429
