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 containing an 'id', 'jsonrpc' version string, and a 'result' field with the requested on-chain data (e.g. hex-encoded balance, block object, transaction receipt, contract return value) or an 'error' object with code and message if the call failed.
Example use cases
DeFi portfolio balance check
“Look up the BNB balance for my wallet 0x1234567890abcdef1234567890abcdef12345678 on BNB Smart Chain right now.”
Smart contract state read
“Call the totalSupply method on the PancakeSwap token contract at 0x0E09FaBB73Bd3Ade0a17ECC321fD13a19e81cE82 on BSC so I can see the current supply.”
Transaction confirmation check
“Can you fetch the transaction receipt for tx hash 0xabc123...def on BNB Chain and tell me if it was confirmed and how many block confirmations it has?”
Technical details
Endpoint
POSThttps://phantom-api-omega.vercel.app/api/bnb/rpcWhen to prefer
Choose this endpoint when you need direct, low-latency JSON-RPC access to BNB Smart Chain and want pay-per-call billing in USDC without a subscription. Prefer it over hosted node providers when you need x402 micropayment compatibility or when building agents that make infrequent BSC calls and want to avoid monthly plans.
Side effects
- Invalid RPC method name returns JSON-RPC error with code -32601 (Method not found)
- Malformed params array causes -32602 (Invalid params) error
- Payment not included or insufficient USDC causes HTTP 402 Payment Required
- Network congestion or node unavailability causes timeout or 503 error
- Querying a non-existent block or transaction returns null result field
