## 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 quickbuild-web-summarizer-a4c3ab50
```

Example prompt: Can you give me a medium-length summary of https://openai.com/research/gpt-4 with up to 5 key points, focusing on 'capabilities'?

## When to prefer this

Choose this endpoint when you need a fast, structured AI summary of any public webpage or raw text, especially when you also need extracted entities, sentiment, topics, and key facts in a single call. It is ideal for content pipelines, research assistants, competitive intelligence, and digest generation. Prefer it over generic LLM calls when you want standardized output fields (keyPoints, entities, sentiment) without prompt engineering.

## Known failure modes

- Private or IP-based URLs are refused with an error
- Text exceeding 200,000 characters will be rejected
- URLs that are inaccessible or return non-200 status codes may fail
- Focus parameter exceeding 200 characters will be rejected
- Unsupported ISO 639-1 language codes may produce unexpected output
- Rate limiting or payment failures result in 402 responses

## How this service works

Landing pages ($15), Google Sheets/Apps Script automation ($10), scrapers, scripts & Telegram bots (from $15), broken-link + sitemap audit reports ($10). See a working demo first, pay after.

## Output

Returns a JSON object containing: a plain-text summary (1-8 sentences depending on length setting), an array of key points, detected topics, named entities with types, sentiment label, page title, intended audience, structured facts, ISO 639-1 language code, content type, whether the content was truncated, the number of characters analyzed, and the AI model used.
