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 queried address, chain name, current block number, account nonce, ETH balance as a decimal string (balance_eth), and raw balance in wei (balance_wei).
Example use cases
DeFi bot wallet balance check
“Check how much ETH is in the wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 on Base right now — I need the balance in ETH and the current nonce before I send a transaction.”
Portfolio tracker balance refresh
“Look up the on-chain ETH balance for address 0xAbCd1234567890abcdef1234567890abcdef1234 on Ethereum and tell me the balance in both ETH and wei.”
Wallet activity monitoring
“I want to know the nonce and ETH balance for 0x1234567890abcdef1234567890abcdef12345678 on Base — I'm trying to figure out if this wallet has sent any transactions recently.”
Technical details
Endpoint
GEThttps://tpgoose.ccwu.cc:8443/v1/chain/balance?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, no-account-required lookup of an EVM wallet's native ETH balance and nonce on Base or Ethereum, paid per-call with USDC. Prefer this over hosted RPC services when you want zero setup, or when you need a lightweight balance check without maintaining RPC subscriptions or API keys.
Side effects
- Invalid or malformed 0x address returns an error
- Unsupported chain name (not 'base' or 'ethereum') returns an error
- Missing required query parameters (chain or address) returns a 400-level error
- Temporary RPC node unavailability may cause timeouts or 5xx errors
- Payment failure via x402 results in 402 Payment Required response
