Technical details
Endpoint
POSThttps://x402.quicknode.com/strk-mainnet/When to prefer
Choose this endpoint when you need live, production-grade access to Starknet mainnet — for reading chain state, querying contracts, or submitting transactions on the STRK network. Prefer this over self-hosted nodes for reliability, or over testnet endpoints when you need real mainnet data.
