## 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 toll402-summarize-00cd6be6
```

Example prompt: Can you summarize https://techcrunch.com/2024/05/01/openai-gpt5/ in bullet points, in English, keeping it under 150 words and focusing on the key product announcements?

## When to prefer this

Choose this endpoint when you need a faithful, configurable summary of either a live URL or raw text — especially when style (bullets, paragraph, TL;DR, detailed), language, and word count need to be controlled precisely. Prefer it over general-purpose LLM calls when you want a consistent, pay-per-use summarization API with predictable output format and cost ($0.05/call).

## Known failure modes

- Invalid or inaccessible URL returns an error with ok: false
- Text exceeding 400,000 character limit is rejected
- Unsupported style enum value causes a validation error
- Network timeout fetching the target URL
- Payment not received or insufficient funds returns 402 status
- Empty input with neither url nor text provided fails validation

## How this service works

Faithful summary of a URL or text in the style, length and language you choose.

## Output

Returns a JSON object with ok (boolean), ms (response time in milliseconds), tool name, and a result object containing title (string) and summary (string) formatted according to the requested style, language, and word limit.
