How this service works
Returns the balance of an Ethereum address in wei via eth_getBalance. Takes one query parameter: address (0x + 40 hex). Query: address (0x + 40 hex).
Output
Returns a JSON object with: ok (boolean success flag), result (integer balance in wei), hex (balance as hex string), chain (e.g. 'ethereum'), method (e.g. 'eth_getBalance'), and service name. On error, ok is false and an error string is present.
Example use cases
Portfolio balance snapshot
“Can you check how much ETH is sitting in the wallet 0xAbCd1234AbCd1234AbCd1234AbCd1234AbCd1234? I want the balance in wei so I can track my portfolio.”
Verify wallet is funded before transfer
“Before I send a transaction, can you confirm that 0x71C7656EC7ab88b098defB751B7401B5f6d8976F actually has ETH in it — give me the raw wei balance.”
Monitor treasury wallet balance
“Check the current ETH balance in wei for our treasury address 0xBE0eB53F46cd790Cd13851d5EFf43D12404d33E8 — I need to see if it's dropped below threshold.”
Technical details
Endpoint
GEThttps://ari001.tailb4ac3a.ts.net/v1/ventures/ethereum_contract_abi_service/eth_getbalance?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need the raw wei ETH balance of a specific Ethereum mainnet address with minimal latency. Prefer it over token-balance endpoints when querying native ETH (not ERC-20). It is ideal for pre-flight funding checks, portfolio tracking, or treasury monitoring where you need the precise on-chain native balance.
Side effects
- Invalid address format (not 0x + 40 hex) — request rejected or error response
- Address is valid but has zero balance — returns result: 0, ok: true
- Network or RPC node unavailable — ok: false with error message
- Malformed query parameter — HTTP 400 or error in response body
