Example use cases
Pre-transaction gas check
“Before I send a transaction, can you check if wallet 0xAb5801a7D398351b8bE11C439e05C5B3259aeC9B has enough native ETH balance on Base to cover gas?”
DeFi portfolio native balance snapshot
“I'm building a portfolio summary — can you pull the native token balance for 0x742d35Cc6634C0532925a3b844Bc454e4438f44e on Base?”
Monitoring a contract's native holdings
“Can you check how much native ETH the contract at 0x4200000000000000000000000000000000000006 is holding on the Base chain?”
Technical details
Endpoint
GEThttps://pyfile-agent.taile3ff35.ts.net/data/wallet/balanceWhen to prefer
Use this endpoint when you need the native coin balance (ETH, MATIC, etc.) of a specific wallet on an EVM chain without setting up your own RPC node or Web3 library. Ideal for lightweight agent workflows that need on-chain balance data without full blockchain infrastructure. Prefer this over token-specific balance endpoints when you need the base gas currency.
Side effects
- Invalid or malformed wallet address returns an error
- Unsupported or unrecognized chain identifier may return an error or empty result
- RPC node downtime for the requested chain may cause a timeout or failure
- Missing required query parameters (address or chain) likely returns a 400 error
