How this service works
JSON-RPC proxy — sonic-mainnet
Output
A standard JSON-RPC 2.0 response object containing the result field with the requested blockchain data (e.g. block number as hex, transaction object, call return value, or account balance), or an error object if the method failed or params were invalid.
Example use cases
Monitor wallet balance changes real-time
“I need you to check my account balance on Sonic mainnet right now. Can you get the current balance for my wallet address and let me know if it's changed since last time we checked?”
Execute smart contract function calls
“Call that token contract on Sonic to get the total supply. I need to know how many tokens are actually in circulation on the mainnet right now.”
Track pending transaction status live
“I just sent a transaction to Sonic mainnet a few minutes ago. Can you look up the transaction receipt and tell me if it's confirmed yet? Here's the transaction hash.”
Technical details
Endpoint
POSThttps://x402.quicknode.com/sonic-mainnet/When to prefer
Choose this endpoint when you need reliable, low-latency access to the Sonic mainnet blockchain via standard Ethereum-compatible JSON-RPC methods, especially when you want a pay-per-call model via x402 without managing API key subscriptions. Prefer over self-hosted nodes when infrastructure management is undesirable.
Side effects
- Invalid JSON-RPC method name returns error code -32601 (Method not found)
- Malformed params array returns error code -32602 (Invalid params)
- Payment not attached or insufficient USDC returns 402 Payment Required
- Network congestion may cause timeout on slow or pending transactions
- Calling non-existent contract address returns empty result rather than an error
