## 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 cerawal-web-summarizer-e071494d -d '<json body>'
```

Example prompt: Can you summarize the content at https://techcrunch.com/2024/05/01/openai-gpt-5-announcement/ and keep the summary under 300 words?

## When to prefer this

Choose this endpoint when you need a quick, pay-per-use text summary of a specific web page without signing up for a subscription service. Ideal for agents that occasionally need to digest external URLs on demand using USDC micropayments via x402.

## Known failure modes

- Invalid or unreachable URL returns an error or empty data
- Payment failure via x402 prevents the request from being processed
- URL behind a paywall or bot-blocker may return incomplete or no content
- maxLength too small may result in an overly truncated or useless summary
- Timeout if the target page is slow to load
