## 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 agent-souk-text-url-summarizer-8be8bfa7 -d '<json body>'
```

Example prompt: Can you give me a bullet-point summary of https://example.com/article in under 100 words, focusing on the key takeaways about pricing?

## When to prefer this

Choose this endpoint when you need a quick, AI-generated summary of either a live web page or a large block of text, with control over output style (paragraph vs bullets), word count, language, and optional focus topic. It is especially useful for agents operating in content-intelligence or research workflows that need to distill information before acting on it. The x402 micropayment model ($0.04 USDC per call) makes it suitable for per-request autonomous agent use without subscription overhead.

## Known failure modes

- URL is inaccessible, paywalled, or returns a non-200 status — endpoint may return an error or empty source
- Both url and text supplied simultaneously — schema expects one or the other, not both
- Text exceeds 100,000 character limit — request rejected
- max_words outside the 20–600 range — validation error
- Unsupported or unrecognized language code — may default or error
- Payment not provided or insufficient USDC — x402 payment-required response
