How this service works
Global structured data and machine-payable tools built for AI agents, developers and intelligent applications.
Output
Returns a JSON object containing the wallet balance in both ETH (human-readable string) and Wei (raw integer string), along with the network name, chain ID, network ID, RPC endpoint used, the asset type, the queried address, a success boolean, and an ISO 8601 timestamp of when the query was made.
Example use cases
DeFi portfolio balance check
“Check the ETH balance for wallet address 0xAbCd1234...5678 — I want to know exactly how much ETH is in there and which network it's on.”
Pre-transaction fund verification
“Before I send a transaction, can you check whether wallet 0x1a2b3c4d...9e0f has enough ETH in it? Show me the balance in ETH.”
Smart contract treasury monitoring
“Look up the current balance of our smart contract treasury at address 0xDead...Beef and tell me the Wei amount and the chain ID.”
Technical details
Endpoint
POSThttps://api.databg.tech/v1/tools/wallet/balanceWhen to prefer
Choose this endpoint when you need a fast, pay-per-call blockchain wallet balance lookup without managing your own RPC node or Web3 infrastructure. Ideal for AI agents that need on-demand balance checks as part of automated workflows, especially when using x402 micropayment rails for frictionless billing.
Side effects
- Invalid or malformed wallet address returns an error or success:false
- Network unavailable or RPC node down causes a timeout or failure response
- Non-Ethereum address formats may not be supported
- Address with no on-chain history may return zero balance with success:true
