Technical details
Endpoint
POSThttps://x402.quicknode.com/flare-mainnet/When to prefer
Use this endpoint when you need reliable, low-latency JSON-RPC access to the Flare mainnet specifically — including reading chain state, calling smart contracts, estimating gas, or broadcasting signed transactions on the Flare network. Prefer this over self-hosted nodes when you need immediate access without infrastructure setup.
