## 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 sitecheck-summarize-eee733cd -d '<json body>'
```

Example prompt: Can you give me a short bullet-point summary of this article in German? https://www.example.com/article-about-climate-policy

## When to prefer this

Choose this endpoint when you need a quick LLM-powered summary of a web page or a block of text, especially when you want structured output (summary + key points), multilingual support, or adjustable length (short/medium/bullets). Prefer this over generic LLM calls when you want a single pay-per-call API that fetches and summarizes a URL in one step without managing your own scraping and prompting pipeline.

## Known failure modes

- URL is unreachable or returns a non-200 status — endpoint may return an error or empty summary
- Text exceeds 12,000 character limit — input may be truncated or rejected
- Unsupported or misspelled language code — summary may default to English or return an error
- Empty input (no URL and no text provided) — returns validation error
- URL points to a PDF or non-HTML resource not supported by the reader — may fail to extract content

## How this service works

A summary of a web page (url) or your own text (up to 12,000 characters) as short, medium or bullets, in the language you name, with key points. Llama 3.3 70B. A page is read as in /api/read, robots.txt respected.

## Output
