## 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 api-anchor-x402-com-cc2534b3 -d '<json body>'
```

Example prompt: Give me a 3-5 bullet TL;DR of this article: https://en.wikipedia.org/wiki/Artificial_intelligence — just the key points, nothing else.

## When to prefer this

Use this endpoint when you need a fast, cheap ($0.01 USDC) bullet-point summary of any web URL or block of text, especially when you want structured key-point extraction rather than a flowing prose summary. Ideal for agents that need to quickly digest long articles, Wikipedia pages, or pasted documents without reading the full content.

## Known failure modes

- URL is unreachable or returns non-200 — likely 422 or 500 error
- Text input is too short or empty — may return error or trivial bullets
- URL points to non-text content (PDF, image, video) — may fail to parse
- Payment not included or invalid x402 header — 402 Payment Required
- Source page behind authentication or paywall — content not accessible
