How this service works
Pay-per-call website uptime/latency/TLS checks and fetch-to-Markdown, measured from Hub Europe (Germany). USDC on Base via x402. No account or API key.
Output
Returns a JSON object containing the human-readable token balance (e.g. '12.5'), the raw integer balance (e.g. '12500000'), the token symbol (e.g. 'USDC'), and the number of decimals (e.g. 6). All fields are derived directly from on-chain data for the specified contract and wallet address.
Example use cases
DeFi portfolio balance check
“Can you look up how much USDC wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 holds on Base using token contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913?”
Verify wallet has enough tokens
“Check if 0xAb5801a7D398351b8bE11C439e05C5B3259aeC9B has at least 100 USDC on Ethereum — the USDC contract is 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48.”
On-chain airdrop eligibility check
“I need to check the token balance of 0x1234567890abcdef1234567890abcdef12345678 for our governance token at contract 0xdeadbeefdeadbeefdeadbeefdeadbeefdeadbeef on Base — can you pull that for me?”
Technical details
Endpoint
GEThttps://kollmz.site:8443/v1/chain/erc20-balance?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a no-account, no-API-key way to fetch an ERC-20 token balance on Base or Ethereum and are comfortable paying $0.002 USDC per call via x402. It is ideal for agents that need lightweight, pay-as-you-go on-chain balance lookups without managing API subscriptions or node infrastructure. Prefer it for one-off or low-frequency queries; for high-volume batch lookups, a dedicated RPC provider may be more cost-effective.
Side effects
- Invalid or malformed EVM wallet address returns an error response
- Unknown or non-ERC-20 contract address may return zero balance or an error
- Unsupported chain value (not 'base' or 'ethereum') results in a validation error
- Payment failure or insufficient USDC for x402 fee results in 402 Payment Required
- Network or RPC downtime may cause timeout or server error
- Address with no token holdings returns a balance of '0' with raw '0'
