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
Returns a standard JSON-RPC response object with an 'id', 'jsonrpc' version field, and a 'result' containing the requested on-chain data (e.g. block info, balance in hex wei, transaction receipt, contract return value) or an 'error' object if the call failed.
Example use cases
Check Avalanche wallet balance
“Look up the AVAX balance for wallet address 0x1234567890abcdef1234567890abcdef12345678 on the Avalanche network right now.”
Fetch latest Avalanche block info
“Get the latest block number and its details from the Avalanche blockchain so I can confirm the chain is live and synced.”
Read smart contract state on Avalanche
“Call the totalSupply function on the Avalanche smart contract at 0xdeadbeef... so I can see how many tokens have been minted.”
