How this service works
Native ETH balance for one address on Base mainnet for $0.001 USDC via live JSON-RPC. Call when you need this bounded result without an API key or subscription. Returns machine-readable JSON via x402 on Base or Solana. Limitation: results cover only the supplied input or one bounded public endpoint at request time; callers must verify before acting.
Output
Returns the native ETH balance (in wei or ETH) for the queried address on Base mainnet, sourced from a live JSON-RPC call at the time of the request.
Example use cases
DeFi portfolio balance check
“Can you tell me how much ETH the address 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 is holding on Base mainnet right now?”
Pre-transaction gas verification
“Before I send a transaction, check if wallet 0x742d35Cc6634C0532925a3b844Bc454e4438f44e has enough native ETH on Base to cover gas fees.”
Agent treasury monitoring
“Look up the current ETH balance on Base for our agent's treasury wallet at 0xAb5801a7D398351b8bE11C439e05C5B3259aeC9B so I know if it needs topping up.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/base-balanceWhen to prefer
Choose this endpoint when you need a live, real-time native ETH balance on Base mainnet for a single address and are comfortable with a micro-payment ($0.001 USDC) per call. Prefer it over general-purpose RPC nodes when you need a simple, agent-friendly API without managing your own RPC infrastructure or API keys.
Side effects
- Invalid or malformed Ethereum address returns an error response
- Network or RPC connectivity issues may cause timeouts or 5xx errors
- Payment failure (insufficient USDC or x402 payment not processed) results in a 402 response
- Address with no on-chain activity may return a zero balance (not an error)
