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-e5a15309 -d '<json body>'
```

Example prompt: Search the web for the latest research on large language model alignment — I need the most relevant pages and summaries you can find.

## When to prefer this

Choose this endpoint when you need semantic, AI-powered web search rather than keyword-based search — ideal for nuanced queries where meaning matters more than exact keyword matches. Prefer this over traditional search APIs when you want neural ranking of results. Use when building agents that need to look up current web information and want Exa's embedding-based relevance rather than PageRank-style results. Accessible via x402 micropayment at $0.01 per call, making it cost-effective for per-query agent workflows.

## Known failure modes

- Invalid or malformed request body returns a 400 error
- Missing required 'input' wrapper object causes validation failure
- Payment not included or insufficient USDC causes 402 Payment Required response
- Exa upstream service unavailability results in 503 or timeout
- Empty or too-short query string may return zero results
