## 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-findsimilar-70c50245 -d '<json body>'
```

Example prompt: Find me 10 web pages that are similar to https://en.wikipedia.org/wiki/Artificial_intelligence — I want pages covering the same topic or closely related content.

## When to prefer this

Use this endpoint when you have a specific URL and want to discover other pages covering the same topic or similar content — ideal for content research, competitive analysis, or expanding a reading list around a known reference page. Prefer over a keyword search when you want semantic similarity based on full page content rather than matching query terms.

## Known failure modes

- Invalid or unreachable source URL returns an error or empty results
- Requested numResults exceeds available similar pages, returning fewer results than asked
- Source URL not indexed by Exa returns low-quality or unrelated results
- Rate limiting or payment failure returns a 402 or 429 error
