How this service works
Coinlight charges USDC per API call with the x402 protocol on Solana and Base.
Output
A JSON response containing the live ETH balance and USDC balance for the queried Base mainnet address, read directly from the chain at the time of the request.
Example use cases
Pre-payment wallet verification
“Before I send USDC on Base, can you check whether 0xa30f3C68f2F6067EE5b9d5f651426E44Ea8AdAE9 actually has enough USDC to cover the payment?”
Portfolio balance snapshot
“Pull the current ETH and USDC balance for my Base wallet 0xa30f3C68f2F6067EE5b9d5f651426E44Ea8AdAE9 so I can see where I stand right now.”
Counterparty due diligence
“I'm about to do a deal with someone on Base — can you check how much ETH and USDC their address 0xa30f3C68f2F6067EE5b9d5f651426E44Ea8AdAE9 is holding on-chain?”
Technical details
Endpoint
GEThttps://coinlight-app.vercel.app/p/base-balance?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time, live on-chain ETH and USDC balances for a specific address on Base mainnet. Prefer it over Ethereum mainnet or Solana balance checkers when the target is specifically on Base (Coinbase's L2). It is a lightweight, keyless lookup — no wallet connection or authentication required beyond the x402 micropayment.
Side effects
- Invalid or malformed 0x address returns an error
- Address with no on-chain activity may return zero balances rather than an error
- Network or RPC issues on Base mainnet could cause timeouts or stale data
- Missing required 'address' query parameter returns a validation error
