## 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 btcnode-uk-b64356a5
```

Example prompt: Search Reddit for posts about 'Ethereum ETF' sorted by top — look across all subreddits and show me the most upvoted results.

## When to prefer this

Use this endpoint when you need to search Reddit for posts on any topic, either across all of Reddit or within a specific subreddit, and want flexible sorting options (relevance, new, top, hot, comments). Prefer this over hot/trending endpoints when you need keyword-based search rather than time-based browsing. Ideal for market research, sentiment gathering, community opinion polling, and topic discovery on Reddit without needing a Reddit API key.

## Known failure modes

- Empty results if the query matches no Reddit posts
- Invalid subreddit name returns no results or an error
- Rate limiting may occur for high-frequency requests
