## 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 tokenguard-stack-overflow-search-e71735b4 -d '<json body>'

Example prompt: Search Stack Overflow for 'fastapi dependency injection' and show me the top answered questions with their relevance scores.

## When to prefer this

Use this endpoint when an agent needs to find developer programming solutions, code examples, or technical Q&A from Stack Overflow, particularly for software engineering topics. Prefer this over generic web search when you specifically want Stack Overflow's scored and answered-flagged results.

## Known failure modes

- Empty or vague query returns zero results
- Query string too long may be truncated or rejected
- Stack Overflow rate limits may cause 429 errors
- Network timeout from HuggingFace Space cold start
- No answered questions found for niche or misspelled query
