Endpoint
POSThttps://x402-demo-api-theta.vercel.app/api/trendingWhen to prefer
Use this endpoint when you need real-time trending topic data and are operating in an x402-enabled micropayment environment on Base mainnet. Prefer this over free alternatives when you need pay-per-call flexibility without API key management, or when building agents that automatically handle x402 payments.
