How this service works
Machine-payable URL observations and Base wallet reads, with x402 settlement receipts.
Output
Returns a JSON object with: a success flag (ok), the asset name (USDC), chain name (Base), chain ID (8453), the queried wallet address, USDC balance as a human-readable decimal string (balanceUsdc), the raw atomic balance (balanceAtomic, in 6-decimal USDC units), the block number at which the balance was read, the timestamp of the check (checkedAt), and the data source description (Base mainnet JSON-RPC eth_call).
Example use cases
Pre-payment USDC sufficiency check
“Before I send that payment, check if wallet 0x2dc4309f29a1ad89bea07059c4633a33f8238e5b has enough USDC on Base to cover it — what's the current balance?”
Portfolio USDC balance tracking
“Pull the current USDC balance on Base for my wallet 0xAbCd1234567890AbCd1234567890AbCd12345678 so I can update my portfolio spreadsheet.”
Recipient wallet verification
“Can you check the USDC balance on Base for address 0x9F3a2B1c4D5E6F7A8B9C0D1E2F3A4B5C6D7E8F9A before I send funds there — I want to confirm it's an active wallet.”
Technical details
Endpoint
GEThttps://vytrel-control.vercel.app/api/base-usdc-balance?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need the USDC token balance on Base mainnet for an EVM wallet address. Prefer it for lightweight, real-time balance checks without needing full blockchain node access. It is ideal for pre-transaction validation, portfolio monitoring, or any agent workflow that needs a quick stablecoin balance lookup on the Base L2 chain.
Side effects
- Invalid or malformed EVM wallet address returns an error or empty balance
- Network or RPC node unavailability may result in a timeout or failed response
- Non-existent wallet address returns ok:true with zero balance rather than an error
- Rate limiting may occur if the endpoint is called too frequently
