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 containing the requested on-chain data such as account balances, block details, transaction receipts, smart contract return values, or other Monad network state — depending on the method called.
Example use cases
Check Monad wallet balance
“What's the current token balance for wallet 0xDEADBEEF...1234 on Monad? Use eth_getBalance with the latest block.”
Read smart contract state
“Call the Monad smart contract at 0xCONTRACT...5678 using eth_call to read its totalSupply value — I need the current on-chain state.”
Fetch latest Monad block info
“Get me the details of the latest block on the Monad blockchain, including its hash, timestamp, and transaction count.”

POSThttps://phantom-api-omega.vercel.app/api/monad/rpc?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fast, pay-per-call access to the Monad blockchain specifically, without committing to a subscription RPC provider. Ideal for agents that need occasional or bursty Monad network queries with micropayment billing via x402.
Side effects
- Invalid RPC method name returns an error response
- Malformed params array causes a parse or invalid params error
- Payment not processed (x402) results in 402 Payment Required response
- Monad network downtime or congestion may cause timeouts
- Unsupported eth_ methods not available on Monad return method-not-found errors
