How this service works
Free Base wallet-state sample for the service receiver. The paid $0.0035 API returns native ETH balance, next nonce, and contract/account classification in one bounded read-only batch.
Output
A structured batch response containing: (1) the native ETH balance of the queried Base address, (2) the next pending nonce for that address, and (3) a classification indicating whether the address is a smart contract or an externally owned account (EOA).
Example use cases
Pre-flight check before sending ETH
“Before I send ETH from this wallet on Base, can you pull up the current balance and next nonce for 0xAbCd...1234 so I can make sure the transaction will go through?”
Verify if address is a smart contract
“I need to know whether 0xDeFg...5678 on Base is a smart contract or a regular externally owned account — can you classify it for me?”
DeFi bot wallet monitoring
“Check the wallet state for my bot address 0x9876...FEDC on Base and tell me the ETH balance and current nonce so I can decide if it needs topping up.”
Technical details
Endpoint
GEThttps://appearing-clinics-show-wrote.trycloudflare.com/base-wallet-state-sampleWhen to prefer
Choose this endpoint when you need ETH balance, nonce, and contract/EOA classification for a Base L2 address in a single efficient call, rather than making three separate RPC requests. Prefer it over raw RPC calls when you want a normalized, bounded response format. Best suited for pre-transaction checks, wallet monitoring, and on-chain identity classification on Base network specifically.
Side effects
- Invalid or malformed address returns an error response
- Address with no on-chain activity may return zero balance and nonce 0
- Network congestion or RPC issues may cause timeouts
- The free sample endpoint returns fixed example data rather than live wallet data for an arbitrary address
