Example use cases
DeFi portfolio ETH balance snapshot

On-chain wallet monitoring alert
“Check the current ETH balance for wallet address 0x742d35Cc6634C0532925a3b844Bc454e4438f44e on Ethereum mainnet — I want to know if it's above zero.”
Smart contract audit wallet check

Technical details
Endpoint
POSThttps://agent.pocket.network/v1/wallet-portfolio?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, keyless, pay-per-request native ETH balance lookup on Ethereum mainnet (chain ID 1) without setting up an account or API key. It is ideal for agents that need occasional, ad-hoc wallet balance checks and want to pay micro-fees in USDC. Not suitable when ERC-20 token balances are needed, or when querying chains other than Ethereum mainnet.
Side effects
- Invalid or malformed Ethereum address returns an error or empty data object
- Unsupported chain_id results in no data or an error response
- Network congestion or RPC node unavailability may cause timeouts
- Payment failure (insufficient USDC) results in HTTP 402 and no data returned
- Address with no ETH returns a zero balance, not an error
