## 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-weakness-signal-scanner-2697adb1 -d '<json body>'
```

Example prompt: Search the r/personalfinance subreddit for any user-reported weaknesses or complaints about EXP-18 — give me up to 5 results so I can see what pain points people are flagging.

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call scan of Reddit community posts for product weakness signals without setting up a full social listening pipeline. It is ideal for spot-checking a specific subreddit for bug reports, complaints, or vulnerability mentions about a known product identifier. Prefer alternatives if you need real-time streaming, historical data beyond the public RSS window, or coverage across multiple subreddits simultaneously.

## Known failure modes

- NO_MATCHED_SIGNALS status returned when no weakness-related posts are found in the subreddit
- Empty reports array when subreddit has low activity or no relevant content
- Invalid subreddit name pattern (must be 2-32 alphanumeric or underscore characters) causes request rejection
- Query string exceeding 200 characters will be rejected by schema validation
- Limit value outside 1-5 range causes validation error
- Payment failure via x402 protocol returns HTTP 402 before any data is returned
- Subreddit may be private or banned, resulting in no accessible RSS data
