How this service works
Lightning-fast access to blockchain data, smart contract insights, and Web3 infrastructure across 57+ networks. Pay-per-call via x402.

Returns a standard JSON-RPC response object containing the result field with on-chain data such as block details, account balances, transaction receipts, contract call return values, or event logs depending on the method called.
Example use cases
Check on-chain account balance
“Look up the ETH balance for wallet address 0xAbc123... on the Katana network using the eth_getBalance RPC method.”
Fetch latest block data
“Get the latest block details on the Katana blockchain — block number, timestamp, and transaction count — using eth_getBlockByNumber.”

Choose this endpoint when you need fast, pay-per-call JSON-RPC access to the Katana blockchain network specifically, without committing to a subscription. Ideal for agents that need sporadic on-chain lookups on Katana without managing their own node infrastructure.
Side effects
- Invalid RPC method name returns JSON-RPC error with code -32601 (method not found)

- Payment not included or insufficient USDC results in 402 Payment Required response
- Network congestion or node unavailability may return timeout or 503 errors
- Calling write methods without a signed transaction returns execution error
