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 token's human-readable decimal balance (e.g. '12.5'), the raw integer balance in smallest units (e.g. '12500000'), the token symbol (e.g. 'USDC'), and the number of decimals used.
Example use cases
DeFi portfolio balance check
“Can you look up how much USDC is in wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 on Base? The USDC contract address is 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913.”
Verify token receipt on-chain
“I just sent some tokens to 0xAbC1234...5678 on Ethereum — can you check the ERC-20 balance for contract 0xTokenContract... to confirm they arrived?”
Automated wallet monitoring trigger
“Check the USDC balance on Base for address 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 every hour and alert me if it drops below 5 USDC.”

Endpoint
GEThttps://rabbitholeshot.ccwu.cc:8443/v1/chain/erc20-balance?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, no-account-required ERC-20 balance lookup on Base or Ethereum mainnet, especially when operating in a pay-per-call model without wanting to manage API keys or subscriptions. It is ideal for agents that need occasional on-chain balance checks without committing to a full Web3 data provider.
Side effects
- Invalid or malformed wallet address returns an error
- Unsupported chain value (not 'base' or 'ethereum') returns a validation error
- Invalid ERC-20 contract address (non-existent contract) may return zero balance or error
- Payment failure via x402 results in 402 response and no data returned
- Network timeout from the European hub node causes request failure
