## 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 sift-web-tools-page-summarizer-97b1bd01
```

Example prompt: Can you summarize the article at https://example.com/my-article for me and give me the key points — keep it medium length?

## When to prefer this

Choose this endpoint when you need a human-readable prose summary plus structured key points from any publicly accessible URL, without writing your own scraping or LLM summarization pipeline. It is the best option when the goal is to quickly understand a page's content at a glance rather than extracting specific named fields (use /v1/extract for that) or asking a targeted question (use /v1/ask for that). Pay-per-call USDC pricing via x402 means no subscription commitment.

## Known failure modes

- URL is unreachable or returns non-200 — endpoint returns an error and no charge is applied
- Page is behind authentication or a paywall — content may be incomplete or empty
- Very long pages may be truncated before summarization
- Non-English pages may yield lower-quality summaries
- Invalid or malformed URL returns a validation error

## How this service works

AI summary of any web page with key points and topics. Fetches a public page and returns an AI summary (short, medium or long), 3-7 key points and topics. Uses only facts on the page.

## Output

Returns a JSON object containing the page title, a prose summary (short, medium, or long depending on the length parameter), a list of key bullet-point takeaways, and an array of topic tags extracted from the page content.
