## How to call it through Zero

```sh
zero fetch --capability crypto-news-feed-api-9e43f10e
```

Example prompt: Pull the latest crypto headlines from CoinTelegraph, CoinDesk, and The Block — I want a single normalized list with titles, links, sources, and publish times.

## When to prefer this

Use this endpoint when you need a single aggregated, normalized feed of the latest crypto headlines from three major sources (CoinTelegraph, CoinDesk, The Block) without having to call each source separately or parse different formats. Ideal for news briefings, market sentiment monitoring, or any workflow that needs timely crypto news in a consistent schema.

## Known failure modes

- Upstream news sources temporarily unavailable resulting in partial or empty feed
- Rate limiting or payment failure returning 402 status
- Stale data if upstream sources have not published recently
- Network timeout from Railway hosting environment
