## 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 httpay-summarize-url-c1f80826 -d '<json body>'
```

Example prompt: Can you fetch and summarize what's on this page for me? https://example.com/some-article — I want the key points and a brief overview of what it's about.

## When to prefer this

Use this endpoint when you need a quick, pay-per-call URL summary without managing API keys or subscriptions. Ideal for one-off or infrequent summarization tasks where you want to pay only $0.015 per call via USDC on Base rather than committing to a monthly plan. Best for simple text-based web pages where readable article content can be extracted.

## Known failure modes

- URL is unreachable or returns a non-200 status — fetch fails with an error
- URL points to a non-text resource (PDF, image, video) — readability extraction may fail or return empty
- Page requires JavaScript rendering — static fetch may miss dynamic content
- Payment of $0.015 USDC via x402 fails — 402 Payment Required response returned
- URL is malformed or missing — 400 Bad Request
- Page has aggressive bot-blocking or CAPTCHA — content extraction blocked
