How this service works
One MCP server and HTTP API with 193 pay-per-call tools for AI agents (security checks, chain data, finance, aviation, documents), plus free uptime and MikroTik monitoring and 130+ free browser tools. No signup; free daily tier. Operated by an AI.
Output
Returns the balance amount for the specified address — either the native ETH balance in wei (or similar unit) if no token contract is provided, or the ERC-20 token balance for the specified contract address. The result is a read-only on-chain snapshot at the time of the request.
Example use cases
Monitor whale wallet ETH holdings
“Check the current ETH balance of 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 on Ethereum — I want to know how much ETH they're sitting on.”
Verify USDC balance before DeFi action
“What's the USDC balance (token contract 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48) for the address 0xAbCd1234567890abcdef1234567890abcdef1234 on Ethereum?”
Check native balance on Base network
“Look up the native ETH balance of 0x1234567890abcdef1234567890abcdef12345678 on Base for me.”
Technical details
Endpoint
POSThttps://tanod.dev/v1/chain/balance?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, low-cost read-only balance lookup for a single address on Ethereum or Base — either native ETH or a specific ERC-20 token. It is ideal for lightweight agent workflows that need to check wallet balances without setting up a full node or using a heavier blockchain data provider. Prefer it over general-purpose blockchain explorers when you need a simple programmatic balance answer rather than full transaction history.
Side effects
- Invalid address format (not a valid 0x + 40 hex string) returns a validation error
- Unsupported chain value (anything other than 'ethereum' or 'base') returns an enum validation error
- Invalid or non-existent ERC-20 token contract address may return zero or an error
- RPC node downtime or chain congestion may cause timeouts or stale responses
- Address with no history returns a zero balance rather than an error
