Output

Endpoint
GEThttps://anibalb.duckdns.org/x402/trending-crypto?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a no-account, no-API-key, pay-per-call lookup of currently trending crypto tokens paid in USDC via x402 on Base. Prefer it for lightweight agentic workflows where you want real-time trending coin discovery without subscription overhead. If you need deep market metrics (price history, OHLCV, order books), a dedicated market data API like CoinGecko or CoinMarketCap would be more appropriate.
Side effects
- Payment not included or insufficient USDC — returns HTTP 402 Payment Required
- Network or DNS instability on duckdns.org host causing timeouts or connection errors
- Upstream crypto data source unavailable leading to empty or stale trending list
- Malformed response if the underlying data provider returns unexpected schema
