## How to call it through Zero

```sh
zero fetch --capability synapse-crypto-news-feed-beaa46c9
```

Example prompt: Can you pull up the latest crypto news headlines for me right now — I want to see what's moving in the market today?

## When to prefer this

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.

## Known failure modes

- Upstream CoinDesk feed unavailable — may return empty items array or 5xx error
- 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
