## 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 amanchain-text-url-summarizer-8221f7c0 -d '<json body>'
```

Example prompt: Can you summarize this article for me and give me the key takeaways? Here's the URL: https://example.com/long-article-about-climate-change

## When to prefer this

Choose this endpoint when you need a pay-per-call, account-free text or URL summarization with no API key setup — ideal for agents that need occasional on-demand summarization billed in USDC via x402 micropayments. Prefer alternatives if you need bulk summarization, streaming output, or fine-grained control over summary length and format.

## Known failure modes

- URL is inaccessible or returns a non-200 status — service may return an error or empty result
- Input text is empty or malformed JSON body — returns a 400-level error
- Payment not settled or x402 handshake fails — request is rejected before processing
- URL behind a paywall or login wall — content cannot be fetched and summary will be incomplete or fail
- Very short input with nothing to summarize — output may be trivially short or echo the input
