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 JSON object containing the network name, native token symbol, optional ERC-20 token metadata (name, symbol, decimals), an array of per-wallet records each with native and token balances, plus aggregate totals for native and token balances across all submitted addresses.
Example use cases
Treasury multi-wallet balance snapshot
“I manage a DAO treasury spread across 12 wallets on Arbitrum — can you pull the ETH and USDC balances for all of them and tell me the totals so I know our current holdings?”
Airdrop distribution verification
“We just airdropped our token to 40 addresses on Polygon. Can you check all their token balances and give me a breakdown so I can confirm everyone got the right amount?”
Whale wallet monitoring on Ethereum
“I'm tracking 20 large Ethereum wallets. Pull their ETH and USDT balances right now and show me the combined total along with each wallet's individual amount.”
Technical details
Endpoint
POSThttps://api.vextorium.com/v1/evm-balances-batch?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to check balances for multiple EVM wallets (up to 50) in a single API call across any of 12 supported chains. It is ideal for treasury management, airdrop verification, whale tracking, or any scenario where calling a single-address balance endpoint repeatedly would be inefficient. It uniquely combines native and ERC-20 balance lookup with pre-computed totals, saving downstream aggregation work.
Side effects
- Invalid or malformed wallet address causes an error or null balance for that entry
- Unsupported chain specified returns a validation error
- More than 50 addresses submitted may be rejected or truncated
- Invalid ERC-20 token contract address results in null token data
- Network congestion or RPC errors may cause partial or failed responses
- Missing required 'addresses' field returns a schema validation error
