## How to call it through Zero

```sh
zero fetch --capability questflow-e719b4a1 -d '<json body>'
```

Example prompt: Search the web for the latest research on transformer attention mechanisms and give me the top results with summaries.

## When to prefer this

Use this endpoint when you need neural/semantic web search powered by Exa, which excels at finding high-quality, relevant results for research-oriented or nuanced queries — particularly when keyword-based search would miss the intent. Prefer over generic search APIs when semantic relevance and document quality matter.

## Known failure modes

- Empty or vague query returns low-quality or no results
- Rate limiting or quota exceeded if too many calls are made
- Query too broad may return irrelevant results
- Network timeout if Exa's backend is slow
- Payment failure (x402) if USDC balance is insufficient
