## 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 dotrockets-x402-summarize-url-or-text-summarization-4f7aa5ce
```

Example prompt: Can you give me a short summary in English of the article at https://example.com/some-long-article — use the dotrockets summarize tool and pay with USDC?

## When to prefer this

Choose this endpoint when an agent needs to condense a webpage or raw text into a digestible summary, especially when multilingual output is required and no API key or signup is feasible — ideal for autonomous agents using x402 micropayments on Base.

## Known failure modes

- URL unreachable or blocked — endpoint may return an error or empty summary
- Invalid or unsupported language code — may return summary in default language or error
- Both 'url' and 'text' omitted — no content to summarize, likely returns error
- Payment failure via x402 — call not processed if USDC payment rejected
- Very long text input may exceed processing limits

## How this service works

Machine-payable APIs for AI agents over x402: cosmic live data, AI-visibility scoring, website screenshots, and scrape-to-markdown. Pay per call in USDC on Base. No API keys, no signup.

## Output

Returns a JSON object with a 'summary' string containing the condensed content, a 'length' field indicating the requested summary length (short/medium/long), and a 'source_url' echoing the input URL if one was provided.
