## 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-search-via-402-com-tr-f9ee822e
```

Example prompt: Search the web for the latest news about OpenAI's GPT-5 release — give me 5 results using auto search type, and include highlighted excerpts from each page.

## When to prefer this

Choose this endpoint when an AI agent needs real-time web search results that go beyond its training cutoff, without requiring a separate Exa account or subscription. It is ideal for one-off or low-frequency search tasks billed per call in USDC, especially when domain filtering or page-level text highlights are needed. Prefer this over static knowledge retrieval when recency matters — news, product releases, current prices, or any fast-moving topic.

## Known failure modes

- Missing required 'query' parameter returns a 400 error
- Payment not provided or declined results in a 402 Payment Required challenge with pricing quoted
- numResults outside 1–10 range may be rejected or clamped
- includeDomains with invalid or unreachable domains returns empty results
- text=1 combined with numResults>5 silently caps results at 5
- Queries for very niche or recent content may return low-relevance results if Exa index has not crawled them

## How this service works

Exa's neural web search, resold per call — no Exa account, no subscription, one USDC micro-payment. Pass query= and get ranked results: title, URL, publish date, author, relevance score. numResults=1..10 (default 5). type=auto|fast|instant. includeDomains= restricts the search. Add text=1 for matched highlights from each page (caps results at 5, priced $0.03; the 402 challenge quotes it). For agents that need what the web says today, not what a training cutoff remembers.

## Output

Returns a ranked list of up to 10 web results, each containing: page title, URL, publish date, author name, and a relevance score. If text=1 is requested (capped at 5 results, $0.03/call), each result also includes highlighted excerpts matching the query from the actual page content.
