How this service works
Payment for credits to access Quicknode Core API
Output
A JSON-RPC 2.0 response object containing an id, jsonrpc version string, and result field with the blockchain data (e.g. block hash, transaction hash, or state value) returned by the QuickNode node for the requested network.
Example use cases
Monitor real-time transaction on Polygon
“Check if my transaction went through on Polygon by querying the latest block and looking for my transaction hash. Pay the per-call fee and let me know the status.”
Verify smart contract state across networks
“I need to check the current balance of my token contract on both Ethereum and Arbitrum. Query the state on both networks using x402 payments and give me the results.”
Batch blockchain data for portfolio tracking
“Pull the latest transaction history and balance information for my wallet across Ethereum, Solana, and Base networks. Pay per request and compile everything into a summary for me.”
Technical details
Endpoint
POSThttps://x402.quicknode.com/networksWhen to prefer
Choose this endpoint when you need one-off or infrequent access to QuickNode's Core API across multiple blockchain networks without committing to a subscription, and when you can pay $10 USDC per call via the x402 protocol. Prefer this over the per-request ($0.001) or nanopayment ($0.0001) options when making high-value or infrequent calls where latency and reliability of QuickNode's infrastructure matter more than cost optimization.
Side effects
- Insufficient USDC balance for the $10 per-call fee — payment rejected
- Invalid or unsupported network identifier — endpoint not found
- Malformed JSON-RPC request body — RPC parse error returned
- x402 payment authorization failure — 402 Payment Required with no result
- Network congestion or node unavailability — timeout or 503 error
- Invalid JSON-RPC method for the selected network — method not found error
