## 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-contents-48dff9b5 -d '<json body>'
```

Example prompt: Fetch the full text content and a short summary of these three URLs for me — https://example.com/article1, https://example.com/article2, https://example.com/article3 — and highlight the most relevant sentences about climate policy, doing a live crawl if the cached version isn't available.

## When to prefer this

Use this endpoint when you already have specific URLs and need their full text, structured highlights, or AI summaries — especially after running a search that returned URLs. Prefer this over generic scrapers when you need Exa's live crawl capability, highlight extraction tied to a query, or structured summaries. Best suited for research pipelines where content quality and metadata (author, date) matter.

## Known failure modes

- CRAWL_NOT_FOUND: URL could not be found or does not exist
- CRAWL_TIMEOUT: page took too long to load during crawl
- CRAWL_LIVECRAWL_TIMEOUT: live crawl exceeded the specified timeout
- SOURCE_NOT_AVAILABLE: the source URL is blocked or inaccessible
- CRAWL_UNKNOWN_ERROR: unexpected error during crawling
- Empty results array if all URLs fail
- Partial results when only some URLs succeed

## How this service works

Exa Contents - Retrieve content from URLs

## Output

Returns an array of results per URL, each containing the page's full text, title, author, published date, favicon, image, AI-generated summary, relevant highlight sentences with scores, extracted links, and optional subpage content. Also includes per-URL status (success or error with error tag) and cost breakdown.
