How this service works
Lightning-fast access to blockchain data, smart contract insights, and Web3 infrastructure across 57+ networks. Pay-per-call via x402.
Output
A JSON-RPC response object containing the 'result' field with the requested blockchain data (balance in wei, block object, contract return value, transaction receipt, logs, etc.) or an 'error' object if the call failed.
Example use cases
Wallet balance check on EVM chain
“What's the current ETH balance of wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 on Ethereum mainnet right now?”
Smart contract state read
“Read the totalSupply of the USDC contract at 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum — call the totalSupply() function via RPC.”
Latest block number lookup
“What's the latest block number on Polygon right now? Use eth_blockNumber to check.”

Choose this endpoint when you need low-latency, pay-per-call JSON-RPC access to on-chain data across many EVM-compatible networks without provisioning your own node or committing to a subscription. Ideal for agents making sporadic blockchain queries across multiple chains at $0.01 per call, especially when you want the x402 micropayment flow for trustless, programmatic access.
Side effects
- Invalid or unsupported RPC method name returns a JSON-RPC error object
- Malformed params array causes a parse or invalid params error
- Unsupported network/chain not among the 57+ covered returns an error
- Payment not attached or insufficient USDC causes HTTP 402 Payment Required
- Rate limiting or node downtime returns 503 or timeout
- Contract call reverts on-chain returns execution revert error in result
