## 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 agentfeed-url-summarizer-f9046a0b
```

Example prompt: Can you give me a short summary of this article — https://www.bbc.com/news/science-environment-12345678 — just the highlights in about 60 words?

## When to prefer this

Choose this endpoint when you need a quick AI-generated summary of any publicly accessible web page or PDF without setting up an API key or account — just pay $0.01 USDC per call via x402 or a prepaid key. Ideal for agents that need to distill web content on demand as part of a larger workflow, especially when the URL could be HTML or PDF and you want both a prose summary and structured key points in one call.

## Known failure modes

- URL is unreachable or returns a non-200 status — fetch fails with an error
- URL points to a paywalled or login-required page — content unavailable or minimal
- PDF is scanned/image-only with no extractable text — poor or empty summary
- Very large document exceeds character read limit — truncated flag set to true
- Invalid or non-HTTP URL provided — validation error on queryParams.url
- Payment not completed via x402 or invalid prepaid key — 402 Payment Required response

## How this service works

Page or PDF summary: a short or medium summary with key points, and says whether the document was cut at 20,000 tokens and how much was read. Use when you need to answer: What does this page or PDF say, in short? Uses only what the document says.

## Output

A JSON object containing the AI-generated summary (short ~60 words or medium ~150 words), an array of key bullet-point takeaways, the page title, source and final URL, character counts, estimated token count, fetch timestamp, model used, and whether the result was cached or the content was truncated.
