## 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 oassis-exa-web-search-1485fddf
```

Example prompt: Search the web for the latest information about the Model Context Protocol specification and give me the top relevant URLs and page titles.

## When to prefer this

Choose this endpoint when you need to discover relevant URLs and page titles for a topic without scraping a specific known URL. It is ideal for open-ended research, finding documentation, or gathering a list of sources before deeper scraping. Prefer it over a direct scrape endpoint when you don't already know the target URLs. The pay-per-call model with no signup makes it suitable for ad-hoc agent workflows.

## Known failure modes

- Empty results if the query is too narrow or obscure
- Payment failure if wallet has insufficient USDC balance
- Rate limiting or timeout if the Exa search engine is overloaded
- Malformed request if required body fields are missing
- Stale or irrelevant results for highly niche or very recent queries

## How this service works

Scrape any page or document to markdown, map and crawl whole sites, and drive a real browser. Pay per call with a wallet — no API key, no signup, no monthly plan.

## Output

Returns a JSON object containing the search engine name ('exa') and an array of result objects, each with a URL and title for a relevant web page matching the query.
