How this service works
Multi-chain blockchain data API. 7 chains. x402 pay-per-call with USDC on Base.
Output
A standard JSON-RPC response object containing the result field with Ethereum data (balances in wei, block objects, transaction receipts, contract return values, gas estimates, etc.) or an error object with code and message if the call fails.
Example use cases
DeFi portfolio balance checker
“Can you fetch the ETH balance and latest transaction count for wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 on Ethereum?”
Smart contract state reader
“Call the Ethereum smart contract at 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 using the eth_call method with the balanceOf function for address 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 at the latest block.”
Gas fee estimation for transaction
“Estimate the gas needed for a transfer transaction on Ethereum from 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 to 0xAbCd1234 with a value of 1 ETH so I can figure out the current cost.”
Technical details
Endpoint
POSThttps://chain.gpuops.io/v1/rpc/ethereumWhen to prefer
Choose this endpoint when you need direct Ethereum JSON-RPC access with pay-per-call micropayment billing (no subscription required) and want to avoid managing your own node. Ideal for agents making sporadic or low-volume Ethereum queries where a $0.001/call model is more cost-effective than a subscription RPC provider.
Side effects
- Invalid JSON-RPC method name returns error code -32601
- Malformed params array causes -32602 invalid params error
- Payment failure or insufficient USDC balance returns HTTP 402
- Rate limiting or node unavailability returns HTTP 503 or timeout
- Requesting data for a non-existent block or tx hash returns null result
