Endpoint
POSThttps://pennyrail.vercel.app/api/p/intel/market.x402-trending--x402-market-radar?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time or near-real-time trending intelligence specifically for the x402 protocol ecosystem, and you are operating in a micropayment-capable agent context (x402 protocol with USDC). Prefer this over generic crypto trend APIs when your use case is scoped to x402 markets and you want machine-readable settlement-ready output at very low per-call cost ($0.005 USDC).
Side effects
- Payment not included or insufficient USDC — 402 Payment Required response
- Malformed input object — 400 Bad Request
- Service unavailable on Vercel cold start — 503 or timeout
- Empty or minimal trending data if x402 market activity is low
- Opaque response schema makes downstream parsing brittle
