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 wallet address, chain name, current block number, native ETH balance in both ETH units and wei, and the account nonce — all reflecting the live on-chain state at the time of the query.
Example use cases
Pre-transaction gas check
“Before I send that transaction, can you check if 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 has enough ETH balance on Base to cover gas?”
Portfolio balance snapshot
“What's the native ETH balance right now for wallet 0xAbCd1234567890abcdef1234567890abcdef1234 on Ethereum — give me the amount in both ETH and wei?”
Wallet nonce verification
“Can you look up the current nonce for 0x1234567890abcdef1234567890abcdef12345678 on Base so I know what sequence number to use for my next transaction?”
Technical details
Endpoint
GEThttps://crystalbell.ccwu.cc:8443/v1/chain/balance?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, no-account-required native ETH balance and nonce lookup on Base or Ethereum, paid per-call with USDC via x402. It is ideal for agents that need on-demand blockchain data without committing to a monthly API plan, especially when querying from or routing through Europe.
Side effects
- Invalid or malformed 0x address returns an error
- Unsupported chain value (not 'base' or 'ethereum') returns a validation error
- Payment failure via x402 (insufficient USDC or misconfigured wallet) blocks the request
- Node temporarily unavailable due to connectivity issues from the Germany hub
- Rate-limiting or payment verification timeout
