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 with the wallet's token balance as a human-readable decimal string (e.g. '12.5'), the raw integer balance, the token symbol, and the number of decimals used by the contract.
Example use cases
Verify wallet has enough USDC
“Before I send that payment, check if 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 has at least 100 USDC on Base — the USDC contract is 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913.”
Monitor DeFi treasury token balance
“What's the current DAI balance of our treasury wallet 0xAb5801a7D398351b8bE11C439e05C5B3259aeC9B on Ethereum? DAI contract is 0x6B175474E89094C44Da98b954EedeAC495271d0F.”
Audit airdrop recipient holdings
“Check how many tokens from contract 0x1f9840a85d5aF5bf1D1762F925BDADdC4201F984 the address 0x742d35Cc6634C0532925a3b844Bc454e4438f44e currently holds on Ethereum.”

Endpoint
GEThttps://cyberhill.ccwu.cc:8443/v1/chain/erc20-balance?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, no-account-required on-chain ERC-20 balance lookup for Base or Ethereum without setting up an RPC node or API key. Ideal for lightweight agent workflows that need to verify token holdings before a transaction or decision.
Side effects
- Invalid or non-checksummed wallet address returns an error
- Unsupported chain value (anything other than 'base' or 'ethereum') causes a bad request
- Non-ERC-20 contract address may return zero or an error
- Network congestion or RPC issues may cause timeout or stale data
- Payment failure via x402 if USDC funds are insufficient
