## 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 prediction-market-news-feed-139ff270
```

Example prompt: Pull all prediction-market-relevant news published between 2025-06-01T00:00:00Z and 2025-06-07T23:59:59Z so I can see what stories might be moving odds this week.

## When to prefer this

Use this endpoint when you need raw, timestamped news articles relevant to prediction markets within a specific date window — ideal for monitoring breaking events, building context for market analysis, or feeding news into a downstream model. Prefer over the LLM narrative recap sibling when you need structured article data rather than a summarized story.

## Known failure modes

- Missing publishDateFrom or publishDateTo returns a 400 validation error
- Invalid date format causes a 422 unprocessable entity error
- Date range too wide may result in truncated results or timeout
- No news found for the given window returns an empty result set
- Payment failure (x402) blocks access to the endpoint
