## 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 webbersites-web-page-summarizer-9394a436
```

Example prompt: Can you give me a 5-sentence summary of what this article is actually about? Here's the URL: https://www.bbc.com/news/technology-68123456

## When to prefer this

Choose this endpoint when you need a fast, cheap, deterministic extractive summary of a web page and don't need AI-generated paraphrasing or full-page content. Ideal when you want the literal key sentences from the source text (TextRank), not a rewritten digest. Prefer this over full-scrape endpoints when bandwidth and latency matter and you only need the gist. At $0.015/call it's cost-effective for high-volume summarization pipelines.

## Known failure modes

- URL is not publicly accessible or returns a non-200 status — fetch fails with an error
- Page has no extractable article content (e.g. pure JavaScript SPA, login-walled) — returns empty or low-quality summary
- sentences parameter out of range (not 1-10) — may return default of 3 or a validation error
- Invalid or malformed URL supplied — returns an error response
- Page is too large or times out — fetch may fail with a timeout error

## How this service works

Quick extractive summary of any web page: fetch the URL, extract the main article, and return the key sentences (TextRank) instead of the full text. For agents that want the gist of a page, not a full scrape. No AI — fast and deterministic. Want an abstractive AI rewrite, or to summarize a PDF/DOCX or your own text? POST /api/summarize-text ($0.01).

## Output

Returns a JSON object containing the page title, a concatenated summary string, an array of the top key sentences (up to 10), the word count of the summary, and the word count of the original article text.
