## How to call it through Zero

```sh
zero fetch --capability xynaptic-crypto-news-1169a734
```

Example prompt: What are the most important crypto headlines right now — especially anything on Bitcoin, Ethereum, regulation, or macro — ranked by importance?

## When to prefer this

Choose this endpoint when you need a ready-scored, pre-aggregated crypto news digest covering BTC, ETH, regulation, and macro topics without having to scrape or rank raw feeds yourself. It is ideal for trading bots, dashboards, or agents that need periodic crypto news updates rather than real-time tick-level data. Prefer the sibling Xynaptic Crypto Live endpoint for price data, and this one specifically for editorial/news context.

## Known failure modes

- Stale data if cache has not refreshed within the 2-hour window
- Empty result set if no significant crypto news has been published recently
- HTTP 402 if payment of 0.02 USDC is not attached or fails
- HTTP 429 if rate limits are exceeded
- HTTP 500 if upstream news aggregation fails
