Endpoint
GEThttps://anibalb.duckdns.org/x402/crypto-news?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, no-account-required, pay-per-call fetch of the latest cryptocurrency news headlines from CoinDesk. Ideal for agents that need real-time crypto market context without setting up API keys or subscriptions. Best for lightweight news monitoring rather than deep historical search or multi-source aggregation.

- Payment not processed correctly via x402 — returns 402 Payment Required
- Rate limiting or network issues on the duckdns host — returns timeout or 503
- Feed may return stale articles if upstream RSS/API is not updated frequently
