Technical details
Endpoint
POSThttps://x402.quicknode.com/flow-mainnet/When to prefer
Use this endpoint when you need to interact specifically with the Flow blockchain mainnet via JSON-RPC — for reading on-chain state, querying blocks or transactions, calling Cadence smart contracts, or broadcasting transactions. Prefer this over generic HTTP clients because it provides a paid, reliable QuickNode-backed node connection with high availability.
