# Exa Neural Web Search

> Exa Neural Web Search is a paid API for AI agents from stable-enrich-anncfzk3u-merit-systems.vercel.app, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-12).

Performs neural (semantic/AI-powered) search across the web, returning relevant results based on meaning rather than keyword matching

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 exa-neural-web-search-aa992072 -d '<json body>'
```

Example prompt: Use Exa's neural search to find the most relevant web pages about advances in quantum computing error correction from the past year.

## When to prefer this

Choose this endpoint when you need semantic or conceptual web search rather than exact keyword matching — ideal for finding conceptually related content, recent articles on a topic, or when traditional search would miss relevant results due to vocabulary mismatch. Prefer over standard search APIs when meaning-based retrieval matters more than keyword precision.

## Known failure modes

- Empty or vague query returns low-quality or irrelevant results
- Rate limiting or quota exceeded returns an error
- Network timeout if the search index is slow to respond
- Malformed request body returns a 400/422 validation error
- Payment not completed (x402) results in 402 Payment Required response

## How this service works

Exa Search - Neural search across the web

## Output

Returns a ranked list of semantically relevant web pages including their titles, URLs, publication dates, and text snippets/highlights that match the meaning of the query — powered by neural embeddings rather than traditional keyword indexing.
