Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-exa-neural-web-search-b7ec26c0 -d '<json body>'
```

Example prompt: Search the web for the latest news and analysis on OpenAI's GPT-5 release — I need a neural search that finds semantically relevant articles, not just keyword matches.

## When to prefer this

Choose this endpoint when you need neural/semantic web search that understands meaning and context rather than pure keyword matching. Prefer it over traditional keyword search APIs when the query is expressed in natural language and conceptual relevance matters more than exact term matching. Ideal for AI agents that need to ground responses in current web content.

## Known failure modes

- Invalid or malformed JSON body returns a 400 error
- Missing required 'input' field causes validation failure
- Exa backend unavailability returns a 5xx error
- Payment not included or insufficient USDC balance causes 402 Payment Required
- Query too vague may return low-relevance results
- Rate limiting if too many concurrent requests
