Endpoint
POSThttps://x402.quicknode.com/xai-testnet/When to prefer
Choose this endpoint when you need to interact specifically with the XAI testnet blockchain — for testing smart contracts, querying testnet state, or broadcasting test transactions — and want QuickNode's reliable RPC infrastructure with x402 micropayment access rather than managing your own node or API key subscription.
