## How to call it through Zero

```sh
zero fetch --capability scout-dx-hugen-tokyo-0ae34785
```

Example prompt: Search Stack Overflow for answers about how to handle asyncio event loop errors in Python — I need the most relevant posts and accepted answers.

## When to prefer this

Choose this endpoint when you need to programmatically search Stack Overflow for developer Q&A content, especially in an agent workflow that requires on-demand technical answers. Prefer this over a general web search when the user specifically wants Stack Overflow community answers, accepted solutions, or code-level troubleshooting from that platform. The x402 micropayment model makes it suitable for pay-per-query agent pipelines.

## Known failure modes

- No matching Stack Overflow posts found for the query — returns empty result set
- Query too vague or broad — returns low-relevance results
- Payment not processed (x402 protocol failure) — request rejected before execution
- Rate limiting or server error from the scout service — 5xx response
- Invalid or missing query parameter — 4xx bad request error
