## How to call it through Zero

```sh
zero fetch --capability polynews-news-b0e9fb35 -d '<json body>'
```

Example prompt: Can you pull the news and X posts that were circulating around the time of this Polymarket price spike — the market ID is 'will-trump-win-2024' and it moved sharply on November 6th, 2024 at 2:15 AM UTC?

## When to prefer this

Use this endpoint when you need to understand the specific news or social media catalyst behind a discrete price movement at a known timestamp on a prediction market. Prefer this over the general market-context endpoint when you already know the exact timestamp of the move and want targeted, time-anchored content rather than a broader market briefing.

## Known failure modes

- Invalid or missing timestamp returns 400 error
- Unknown market ID returns empty results or 404
- No news or X posts found near the timestamp returns empty result set
- Grok API downstream failure causes 503 or timeout
- Rate limiting or payment failure returns 402 or 429

## How this service works

## Output

Returns a curated set of news articles and X (Twitter) posts published near the specified price movement timestamp, providing context for what likely caused or accompanied the market movement. Results include source citations and publication times relevant to the price event.
