How this service works
Base wallet readiness snapshot: checksum address, EOA or contract classification, ETH and native USDC balances, transaction nonce, and current block in one response.
Output
A JSON object containing the checksummed wallet address, chain ID, network name, account type (EOA or contract), ETH balance as a string, native USDC balance as a string, transaction count/nonce as a number, current block number, and a checkedAt timestamp — all reflecting the live state of the address on Base mainnet at the moment of the call.
Example use cases
Pre-transaction wallet readiness check
“Before I submit this transaction, check 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 on Base — I need its ETH and USDC balances, its nonce, and whether it's a regular wallet or a smart contract.”
DeFi agent funding verification
“I'm about to trigger a DeFi action for my user — can you snapshot wallet 0xAbC123...def456 on Base mainnet so I can confirm they have enough ETH and USDC and their nonce is current?”
Wallet classification for compliance check
“Is 0x3fC91A3afd70395Cd496C647d5a6CC9D4B2b7FAD a regular externally owned account or a contract on Base, and what are its current ETH and USDC balances?”
Technical details
Endpoint
GEThttps://enough-kate-provide-bennett.trycloudflare.com/wallet-snapshotWhen to prefer
Choose this endpoint when you need a single-call summary of a wallet's readiness on Base mainnet — especially when you need multiple data points (ETH balance, USDC balance, nonce, account type, and block number) simultaneously and want to avoid multiple round-trips. Prefer this over individual balance endpoints when you need to quickly assess whether a wallet can participate in a transaction or DeFi action. It is purpose-built for Base mainnet and is not suitable for other EVM chains.
Side effects
- Missing or malformed address parameter returns a 400 error
- Non-0x-prefixed address fails validation
- Address not found on Base mainnet may return zero balances rather than an error
- Network congestion may cause slightly stale block number data
- x402 payment failure or insufficient USDC for the $0.001 fee returns a 402 Payment Required response
- Cloudflare tunnel downtime may result in connection errors
