## 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 reddit-subreddit-search-api-fetcher-sh-d03218de
```

Example prompt: Search Reddit for subreddits related to 'mechanical keyboards' and show me the top communities that come up.

## When to prefer this

Choose this endpoint when you need to discover Reddit communities by topic or keyword without managing OAuth credentials or a Reddit developer account. It is ideal for agents that need one-off or low-volume subreddit searches billed per call in USDC, with no subscription overhead. Prefer it over direct Reddit API access when avoiding credential management is a priority.

## Known failure modes

- Empty results if no subreddits match the query
- Payment failure if USDC balance is insufficient or x402 payment is rejected
- Rate limiting or throttling if too many requests are made in a short window
- Invalid or malformed query parameter returning a 400 error
- Reddit-side unavailability causing upstream errors
