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
A JSON object containing the wallet address, chain name, native token balance in ETH and wei, the current account nonce, and the block number at which the balance was read.
Example use cases
Pre-transfer balance check
“Before I send ETH, check the current balance of 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 on Base so I know if there are enough funds.”
DeFi bot wallet monitoring
“What is the native ETH balance and nonce for wallet 0xAbC1234567890abcdef1234567890abcdef123456 on Ethereum right now?”
Onchain treasury audit
“Look up the on-chain balance in both ETH and wei for address 0x1234567890abcdef1234567890abcdef12345678 on Base and tell me the current block number.”
Technical details
Endpoint
GEThttps://webthree.ccwu.cc:8443/v1/chain/balance?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, keyless, pay-per-call balance or nonce lookup for an EVM address on Base or Ethereum without setting up an account or managing API keys. It is particularly well-suited for agents operating in Europe (low latency from the German hub) or pipelines that need ad-hoc blockchain data without committing to a subscription. Prefer a dedicated RPC provider (Alchemy, Infura) if you need high-volume queries, multi-chain support beyond Base/Ethereum, or archival data.
Side effects
- Invalid or malformed EVM address returns an error response
- Unsupported chain value (not 'base' or 'ethereum') returns a validation error
- Payment failure via x402 (insufficient USDC or payment not processed) blocks the request
- Node connectivity issues from the European hub may cause timeout or 5xx errors
- Address with no transactions may return nonce of 0 and zero balance, which is valid but could be confused for an error
