## 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 crypto-news-signal-da9fe07a
```

Example prompt: Pull the latest crypto news headlines for bitcoin — I want the sentiment breakdown, positive and negative keyword hits, and an overall market tone summary, give me the top 12 results.

## When to prefer this

Choose this endpoint when you need low-cost, no-API-key crypto news sentiment with keyword-level heuristic scoring and aggregate market tone — ideal for trading agents, research bots, or market monitors that need quick sentiment signals without configuring external news API credentials. Prefer alternatives if you need real-time streaming data, deep NLP-based sentiment models, or news from non-crypto domains.

## Known failure modes

- Public feed unavailable or rate-limited, returning empty results or error
- Query keyword returns no matching articles
- Payment of $0.001 USDC not processed, resulting in 402 response
- Invalid query parameter type causing schema validation error
- Limit parameter out of expected range returning default or error
