## 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 stableenrich-find-similar-ba25b65a -d '<json body>'
```

Example prompt: Find me 10 pages similar to https://www.techcrunch.com that were published after January 1, 2024 — I want the full text content included in the results.

## When to prefer this

Use this endpoint when you have a specific URL and want to discover semantically similar pages — ideal for competitive research, content recommendation, finding related articles, or discovering alternative sources. Prefer this over keyword search when you want similarity based on the full content and meaning of a page rather than specific terms.

## Known failure modes

- Invalid or unreachable URL returns error
- URL with no indexed similar pages returns empty results array
- Domain filter excludes all matching results
- Date range too restrictive returns fewer results than requested
- livecrawl timeout causes partial content retrieval

## How this service works

Pay-per-request access to FullEnrich, CompanyEnrich, LeadMagic, Exa, Firecrawl, Google Maps, Serper, and Whitepages APIs. No auth, no subscriptions.

## Output

An array of similar web pages, each with URL, title, relevance score, optional full text, summary, highlights, published date, author, favicon, and extracted links. Also includes request ID and cost breakdown.
