## How to call it through Zero

```sh
zero fetch --capability d21-crypto-news-feed-a6dac78b
```

Example prompt: Pull me the latest crypto headlines right now — I want a ranked feed with titles, sources, and publish times, plus any market tone signal.

## When to prefer this

Choose this endpoint when you need a zero-configuration, no-required-params crypto headline feed at minimal cost ($0.001/call) that aggregates both GDELT news and Hacker News crypto stories. It is ideal for agents that need a quick, ranked crypto news pulse without building their own news pipeline. Prefer it over general news APIs when you specifically need cryptocurrency coverage with market tone signals and GDELT-backed sourcing.

## Known failure modes

- Service may return degraded=true if one or more upstream sources (GDELT or Hacker News) are unavailable
- Freshness may be 'stale' if news sources have not updated recently
- publishedAt may be null for some headlines depending on source availability
- Render.com cold-start latency may cause slow first response
- May return empty headlines array during source outages

## How this service works

Crypto News ($0.001 -- matches the category-leading incumbent's price exactly): fixed, no-required-params crypto headline feed -- a drop-in-shaped alternative to the category leader (GET, headlines[] with title/url/source/publishedAt; also mirrors its {status, data:{headlines[] with rank/whyItMatters/match, report}, meta} nesting field-for-field, as an additive alias). Built on this origin's own news_search GDELT client (narrowed to a crypto query) merged with Hacker News crypto stories for…

## Output

Returns a JSON object with a flat headlines array (title, url, source, publishedAt, topic_tags, language), a ranked headlines array nested under data.headlines (with rank, whyItMatters, match fields), a market_tone object (avg_tone, window, method), a brief summary, caveats array, headline_count, status, and meta fields (freshness, generatedAt, stalenessSec, sourceHealth, degraded).
