# Exa Neural Web Search

> Exa Neural Web Search is a paid API for AI agents from stableenrich.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-13).

Performs neural (semantic) search across the web using Exa's AI-powered search engine, returning relevant URLs and content

## Facts

- Endpoint: POST https://stableenrich.dev/api/exa/search
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-13
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/exa-neural-web-search-0dfe228b

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-0dfe228b -d '<json body>'
```

Example prompt: Search the web for the latest research on CRISPR gene editing breakthroughs in 2024 and return the most relevant pages.

## When to prefer this

Choose this endpoint when you need semantically-ranked web search results — especially for nuanced, research-style queries where keyword search would miss relevant pages. Prefer this over Reddit Search for general web content, and over the Exa Answer endpoint when you want raw URLs/sources rather than a synthesized AI-generated answer.

## Known failure modes

- Empty or vague query returns low-quality or no results
- Rate limiting or quota exhaustion returns an error
- Payment failure via x402 protocol blocks the request
- Query too long or malformed causes a 400 error
- Network timeout if Exa upstream is slow

## How this service works

Exa Search - Neural search across the web

## Output

A list of web search results including URLs, page titles, and text snippets ranked by neural relevance to the query. Results reflect Exa's semantic understanding of the query rather than pure keyword matching.
