## 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 stableenrich-search-1c99f818 -d '<json body>'
```

Example prompt: Do a neural web search for 'Series A funding rounds in climate tech 2024' and give me the top 5 results with full text and a 2-sentence highlight per page — filter to news and financial report categories only.

## When to prefer this

Choose this endpoint when you need semantically relevant web results rather than keyword-matched results, especially for research, company/people discovery, LinkedIn profiles, GitHub repos, or academic papers. Prefer over keyword search APIs when meaning matters more than exact terms. Use the 'deep' type for comprehensive research tasks and 'fast' for latency-sensitive lookups.

## Known failure modes

- Empty results array if query matches no indexed pages
- Invalid enum value for 'type' or 'category' returns 400 validation error
- Query string missing or empty triggers required-field validation error
- Rate limit or quota exceeded returns 429
- Invalid domain filter syntax may return unexpected empty results
- livecrawl timeout if live page fetch exceeds livecrawlTimeout ms
