## 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 web-page-summarizer-ai-a0009c7e -d '<json body>'
```

Example prompt: Can you give me a medium-length summary of https://en.wikipedia.org/wiki/Transformer_(machine_learning_model), focusing on the attention mechanism?

## When to prefer this

Use this endpoint when you need a fast, cost-effective AI-written summary of any public web page without setting up an account or API key. It is ideal when you want to condense long articles, Wikipedia pages, blog posts, or product pages into digestible text, optionally filtered to a specific topic. Prefer it over raw scraping endpoints when you want a human-readable synthesis rather than raw Markdown, and over general-purpose LLMs when you don't want to pay for both fetching and summarizing separately.

## Known failure modes

- URL is unreachable or returns a non-200 status — service may return an error or empty content
- Page is behind a login wall or CAPTCHA — content cannot be fetched
- focus string exceeds 200 characters — request rejected
- Very short pages may produce minimal summaries
- Pages with mostly non-text content (images, JavaScript-rendered) may yield poor summaries
- Invalid language code may fall back to page language or cause an error

## How this service works

86 APIs for AI agents: web scraping and crawling to Markdown, AI summaries, data extraction and cited answers, screenshots and PDF, PDF, OCR and document conversion, news, paper and developer search and more, paid per call with USDC on Base, Solana, Polygon or Arbitrum via x402. No account, no API key, free sample on every service.

## Output

Returns a JSON object containing the AI-generated summary text, the page title, the model used (e.g. claude-haiku), the requested length, detected or specified language, generation timestamp, source word count, and a flag indicating whether the input was truncated due to length.
