Endpoint
POSThttps://x402.quicknode.com/%7Bnetwork%7D/v1/%7BrestPath%7DWhen to prefer
Use this endpoint when you need pay-per-call access to QuickNode's blockchain REST/JSON-RPC infrastructure across multiple networks without managing API keys or subscriptions — especially suited for agent workflows that make sporadic, multi-chain RPC calls and want to pay with USDC via the x402 protocol.

- Malformed params: incorrect params array returns JSON-RPC error -32602
