## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability ghost77-crypto-news-digest-96840be4 -d '<json body>'
```

Example prompt: Give me a crypto news digest for the last 24 hours focused on AI agents and the Base ecosystem — I want headline bullets with sentiment and source links.

## When to prefer this

Choose this endpoint when you need a concise, pre-formatted markdown news digest with sentiment context rather than raw article data or a full news feed. Ideal for agents that need to brief a user or make a decision based on recent crypto narratives without parsing multiple sources themselves. Particularly useful when filtering by specific tokens or topics like 'Base ecosystem' or 'AI agents'.

## Known failure modes

- No news found for narrow topic/token combination in selected timeframe — returns empty bullets
- Upstream data source unavailable — may return partial digest or error
- Invalid timeframe enum value — returns 400 validation error
- Payment failure via x402 — returns 402 Payment Required before processing
