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 four fields: 'balance' (human-readable decimal, e.g. '12.5'), 'raw' (the on-chain integer before decimal adjustment, e.g. '12500000'), 'symbol' (the token ticker, e.g. 'USDC'), and 'decimals' (the token's decimal places, e.g. 6).
Example use cases
DeFi portfolio balance check
“Can you check how much USDC wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 holds on Base? The USDC contract is 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913.”
Airdrop eligibility verification
“I need to verify whether address 0xAbc123…def456 holds any of our token (contract 0x111…222) on Ethereum before we include them in the airdrop — can you fetch the balance?”
Automated wallet monitoring alert
“Check the current WETH balance for address 0xDEAD…BEEF on Base using the WETH contract address 0x4200000000000000000000000000000000000006, so I can see if it's dropped below a threshold.”

Endpoint
GEThttps://owlorangejuice.bar:8443/v1/chain/erc20-balance?utm_source=zero.xyzWhen to prefer
Prefer this endpoint when you need a no-account, pay-per-call ERC-20 balance lookup on Base or Ethereum, especially when you want to avoid signing up for a full blockchain data provider. Ideal for lightweight agents making occasional balance checks without managing API keys. The x402 micropayment model makes it cost-effective at $0.002 per call.
Side effects
- Invalid or malformed EVM address returns an error
- Unsupported chain value (only 'base' and 'ethereum' accepted)
- Invalid ERC-20 contract address returns an error or zero balance
- Network/RPC timeout from the German hub node
- Payment failure via x402 if USDC balance is insufficient
