How this service works
JSON-RPC proxy — matic-mainnet
Output
Returns a standard JSON-RPC 2.0 response object with the result field containing the requested blockchain data (e.g. hex-encoded balance, block object, transaction receipt, or contract return value), plus the matching id and jsonrpc fields. On error, returns a JSON-RPC error object with code and message.
Example use cases
Example prompt
“Using QuickNode's Polygon mainnet RPC, call eth_getBalance for address 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 and tell me the current MATIC balance.”
Technical details
Endpoint
POSThttps://x402.quicknode.com/matic-mainnet/When to prefer
Choose this endpoint when you need reliable, low-latency RPC access to Polygon (MATIC) mainnet specifically — for reading chain state, submitting transactions, or calling smart contracts. Prefer over self-hosted nodes when you need managed infrastructure with high uptime. Use this over Ethereum or other chain endpoints when the target contract or wallet is on Polygon mainnet.
Side effects
- Invalid JSON-RPC method name returns error code -32601 method not found
- Malformed params array returns error code -32602 invalid params
- Network congestion or node unavailability returns 503 or timeout
- Payment failure (insufficient USDC or x402 auth error) returns 402 Payment Required
- Calling eth_sendRawTransaction with a bad nonce returns execution reverted error
