How this service works
Three pay-per-call tools for agents: Base balance snapshots, public page extraction, and USDC receipt verification. No account or API key.
Output
A JSON object containing the wallet address, chain name ('Base mainnet'), ETH balance, USDC balance and contract address, the Blockscout data source, and an ISO 8601 timestamp of when the data was retrieved.
Example use cases
Pre-payment funding check
“Before I send a USDC payment on Base, can you check whether wallet 0xAbCd1234...5678 has enough USDC — at least 50 — to cover it?”
Portfolio snapshot for DeFi dashboard
“Pull the current ETH and USDC balances on Base for my wallet 0x1234...abcd so I can update my dashboard.”
Onboarding wallet verification
“A new user just registered with wallet address 0xDead...Beef — can you confirm whether it's been funded on Base yet by checking its ETH and USDC balances?”
Technical details
Endpoint
POSThttps://base-wallet-lens.bakongi.chatgpt.site/v1/snapshot?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, no-account, pay-per-call ETH and USDC balance check for a specific Base mainnet address. Prefer it over full blockchain explorers or node RPC calls when you want a simple JSON snapshot without setting up API keys or subscriptions. Ideal for agents that need ad-hoc balance lookups as part of payment workflows, onboarding checks, or portfolio monitoring on Base.
Side effects
- Invalid address format (not a valid 0x hex address) returns a validation error
- Unrecognized or zero-activity address returns balances of '0' rather than an error
- Payment not received or x402 flow failure results in 402 response and no data
- Blockscout API unavailability may cause delayed or failed lookups
- Network timeouts if Base RPC is congested
